No, definitely not. Start discharge directly after the charge has finished, without a break at 0.25C for 2 hours and 20 minutes. Check the PDF product sheets for the fast charge currents on theeneloop lineup pageper battery model. So if the charger senses a change in voltage so that the Voltage drops (which means negative) withinX amount of time it will notice the battery is fully charged. It may be of some use to old batteries that are dying a slow death, but new batteries (especially LSD cells like Eneloop) should have no problem with just using the regular charge method regardless of how long it has been since they were last used. http://budgetlightforum.com/comment/1477075#comment-1477075. List of all Eneloops produced between 2005 and today. datasheet powerex pieza c9000 powerex mh When both of these cycles have a smaller discharge duration of 3 hours the test is considered complete. Another way to remember it is to say, 0.5C is 0.5 times the capacity. So what's the deal -- is it necessary or important to run discharge mode between break-in cycles and / or refresh & analyze cycles? Do I need a special charger? Let`s take a standard Eneloop with a capacity of 1900mAh. Refresh & Analyze will detect a full charge and terminate.

What is the recommended charge current for Eneloops? See the below picture from the Panasonic website. It will charge relatively fast and uses colored LED lights to show whether a battery is empty, still charging, fully charged, or damaged. No, that is unnecessary. You must log in or register to reply here. If you see a .5C it means half of the capacity so in this case the half of 2000 = 1000. This is also allowed at the 100th, 150th, 200th, 250th, etc.

It`s the opposite:To simplify it, you takea battery with 1900mAh and a device (let`s take a flashlight for example)that uses a low current of 100mA. This would imply that you do 25*100mA which would result in 2500mAh. Why can`tyou use that with charging instead of discharging? Eneloop batteries can generally be charged with any kind of NiMH battery charger. But don't go over 2000mAh for AA Eneloops. If you don't need to do it, then how does that work, pumping all of that current into already fully charged batteries? But not everything works well, as you can see above. mAhstands for milli Ampere hour. I just got my first charger -- a used MH-C9000 with 26 Powerex 2700s and some cases for $25 locally off craigslist, which I think is a lucky deal. These chargers can refresh your batteries, and check the capacity! They put their Eneloop Pros in a time based charger and think they are treating their batteries nicely. Aside effect of charging at a high current isheat. And not enough for filling up an Eneloop Pro. Given break-in is used to rescue batteries, especially the weaker ones will suffer excessive wear if they are not fully discharged first; I learned the hard way. Get one, and be happy for many, many years! I believe they can, but under certainconditions. Why is the number from BC1000 about 5% higher? The BQ-CC17 on the other hand does not use this topping off. power pack 24TU edilebilir g paketi SCE4420/10 Power Pack Operation & users manual, 61. I had such instances of batteries falling due to break-in (which were good enough just prior the break-in) because they were not being fully discharged in my attempt to improve a bit their capacity. I believe that is quite a long time. Eneloop batteries are one of the best rechargeable batteries in the world. But at a certain Voltage, the battery stops increasing its Voltage, and therefore the charger could determine to stop charging. It largely depends on the battery; the wrapper design on some brands wrap around the negative end more than others and are therefore more susceptible to tearing. \\. So charging up to1.5 Volts is not bad by itself. The recommended charge ratedepends on the model and size. For a simple charger, I would currently recommend thePanasonic BQ CC55 for Eneloop standard and PRO. This will normally boost the capacity back to its max capacity. A battery charger uses a charge current of 100mA. After analyzing the capacity of your batteries, you should group them by capacity when using them in sets, e.g., if you need 4 batteries for a device and you have a choice of 2440 mAh, 2445 mAh, 2525 mAh, 2570 mAh and 2680 mAh, use the first 4 together (2570 - 2440 = 130; 130 is less than 5% of 2700); do not use the last 4 together (2680 - 2445 = 235; 235 is greater than 5% of 2700). It is according IEC and JIS testing specifications. Just think the case to have a fully charged cell and apply a break-in on it - it will be exactly (and worse) like a dumb slow charger overcharging the battery for 16 hours!!! mAis the unit (milli Ampere) used for thecharging current, which you can compareto"the speed of charging". These 2 checks can be missed when the batteries are charged at low current! powerex datasheet Charging at a slow current can actually be more problematic when the charger can not detect whether a battery is full. Check out the explanation in the advanced section.It is recommended to set a refresh at between 1000-2000mA for charging and 500-1000 discharge rate for regular (white) AA Eneloops. It can be very useful to match batteries for multi-cell applications. Sure. A regular white Eneloop AA has a capacity of 1900mAh. This is also the recommended charge rate by Maha / Powerex. c9000 analyzer nimh nicd powerex Do whatever works for you. There is a test on this website that shows a 10-year-old Sanyo Eneloop still having charge left after 10 years. Often they will only charge batteries in pairs. Instead of measuring whether a Voltage drops, like the aforementioned -dV/dt termination, this one does it in a different way.When a battery is depleted the Voltage is lower than when fully charged. With aRefresh modethe charger will charge, discharge and then do a final charge to complete the cycle. As the battery tester HKJ has pointed out, this type of termination is sometimes difficult to distinguish from a -dV/dt termination.A charger like the Lacrosse BC700 probably uses this termination, especially at a lower current. At least for the break-in, it is highly advised to do a complete discharge first. Some Sanyo and Panasonic chargers in Japan (used to) have a Battery Refresh mode. After the batteries are taken from the charger, the batteries will slowly drop in voltage. They can be charged in your average Eneloop charger unless the charge current is too high. Also notice that the black line, temperature rises at the same time, they go hand in hand. On every Eneloop there is a mAh number written. In real life the mAh depends on a few more factors, like thedischarge currentthat is being used, theageof the battery (how muchused) and the (ambient)temperature. This is meant to keep the battery as full as possible over an extended period of time.

Joking aside, you can do a refresh with the built-in Refresh function on some Panasonic and Sanyo Eneloop chargers. This charger is not recommended to use with the Lite model or older batteries.There is a video onYoutube in Japaneseas well as inEnglishthat will demonstrate the ways this charger works. Just think the case to have a fully charged cell and apply a break-in on it - it will be exactly (and worse) like a dumb slow charger overcharging the battery for 16 hours!!! Flashlight Electronics - Batteries Included. Fill the jug with 1 gallon of water and it`s full. The very popular Panasonic BQ-CC17 charges 1 Eneloop AA battery in about 7 hours. The package claims: Ready to use, and that is correct. Ps. Delta can be translated as a Change. AA std= between 700 and2000mAAA PRO= between 700 and 2500mAAA lite= between 300 and 1000mA, AAA std= between 250 and 750mAAAA PRO= between 300 and 1000mAAAA lite= between 200 and 500mA. When you empty the jug, only 1 gallon of water would come out. cycle.

c9000 powerex analyzer Say for example a flashlight that uses 4 AA batteries in series. If we discharge a battery at 20% speed of the full capacity it should take 5 hours to empty. The battery will take 19 hours to discharge the battery from 1900 till empty. Now you extend the charge time to a total of 25 hours. mh powerex c9000 maha analyzer shashinki Hmm, most likely you won`t be able to do this. Why does my Eneloop charger stop charging at 1.6 Volts and sometimes at 1.45 V? If you are more of a geek take a look at the intelligent analyzer chargers like the Powerex Maha MH C9000, Opus BT-3100/3400, SkyRC MC3000, and the like. You could even extend battery life by not discharging or fully charging the batteries each time. Can I refresh Eneloops if I don't have a charger with a refresh option? Give them a cup of water or even a lollypop will do. New Eneloop batteries need a few cycles to get to max capacity (This is also written in each battery product specifications. You can also mix AA and AAA batteries in the same charger as it will look at the individual bays. powerex c9000 mh charger nimh analyzing test maha mah bettery problem dsc This is a chargetermination method that detects a full battery when the Voltage of the battery drops within a certain time during the charge.- means negatived means delta/changeV means Voltaget means time. If you take care of them, they'll take care of you, Charging your Eneloop batteries AA, AAA, C, and D. Is slow charging better than fast charging for Eneloops? When you charge a battery, the Voltage will rise over time. My quote for max cycle life: "It`s better to stop the charge prematurely with a high charge current than to overcharge with a low charge current.". How are the IEC 61951/ JIS 8708 tests performed so Eneloop batteries can claim a 2100 cycle life? (the cycle tests are done in sets of 50 charges and discharges as can be read here above). When you have a charger that uses acharge current of 100mA, the battery will be fully charged in 19 hours. Take a look at the following graph by HKJ. You can use this method with all NiMH batteries, not just Eneloops. Some advanced chargers will continue this cycle until the max capacity is reached. Noneed tofeel upset.

Just charge them up with the charger you have, and put them in an old-fashioned flashlight with an incandescent bulb, run it until they're completely dead, then charge them up again. c9000 powerex powerex c9000 If you are looking for a new charger, look for one that is made by Panasonic, or any advanced charger I listed on the website.

When using rechargeable NiMH batteries people advise doing a Break-In right out of the package. I get this question asked a lot. They are charged about 70% when leaving the factory.So only if you want to use their full capacity you should charge them before using them. So the continuation of the process may depend on the charger. When you want to know the capacity, or when you want to give them a little boost. Please take a look at this graph below that is taken from a 4th generation Eneloop standard product sheet. Eneloop AA batteries are mostly charged till about 1.5 or even 1.6V. They will charge the batteries for x amount of hours. Smart chargers can detect when a battery is fully charged and usually have a back-up cut-off usinga timer. This means the charge will take 1 hour to charge the battery. NiMH chargers don`t usually include this feature.

If you charge them in a very cold room, your end Voltage will be a bit higher than in a warm room. So that means that my Eneloop batteries can`t be charged 2100 times? If you do an Analyze or Discharge, you should be able to know the capacity, do NOT look at the "charge capacity" during the Break-In! This list is work in progress. Imagine you would charge them twice every week for "just" 1000 times. (This should only be used with an empty battery) The charger willcharge for 16 hours 0.1C charge rate, then rest for an hour, do a 0.2C discharge, rest again, and at the end again charge for 16 hours at 0.1C accordingto their manual. The problem with low C charge rates is that the Voltage drop is difficult to measure. But because of its array of functions, new users may be confused on how to fully make use of its power. No, this has nothing to do with burglars nor with your breakfast. If you don`t care about the charge speed this could be your option. pdf datasheet powerex Tips! powerex datasheet pdf semiconductors power alldatasheet And you could do a refresh on a more advanced charger by setting the mA. A friend of mine, Viking (a member of the CPF forum) has helped me to understand these testings. Please understand this before you proceed with reading. Since the 2700s are not LSD, they are probably discharged already but I would run Refresh & Analyze first rather than Break-In. Disabling it will result in some disabled or missing features. What did you use your flashlight for today. Group batteries with capacity within about +/- 5% of the rated capacity. powerex semiconductors alldatasheet This means that the current will exceed the maximum charge current advised by Panasonic by about 2-3+ times.

(However, this is different from a Refresh or Analyze mode)The Maha Powerex MH -C9000 for example has a Break-In option. How long will Eneloop batteries hold a charge? That is normal behavior. But a Break-In for batteries is referred to asmaximizing the performance or capacity of a battery. And how do they work? New MH-C9000 owner, questions on testing capacity. You can still see all customer reviews for the product. AnAnalyze mode does basically the same thing as it will Analyze the capacity of a battery by charging, discharging, and charging it up again. It is not mainly about the charge current butwhenthe charge stops. Can I use my (fill in brand) charger for Eneloops. Isn`t that the same? Questions about battery Break-In (MH-C9000), Weltool M3vn - Long Runtime Gooseneck Work Light R, WTS: Custom Titanium & Exotic Metals Flashlights, Make maglite 2D shine like 6D without any upgrades. (I don`t know to what Voltage the Powerex will discharge, but according to the IEC standards, section 7.1 it should be to 1V.).

This includes a predefined amount of current for charging and discharging, an ambient temperature of X degrees, anda certain amount of rest within theiramount of charge and discharge cycles. Thisis not recommended.Eneloop lite AA have a minimum of 950 mAh, and Eneloop Pro AA have a minimum of 2500 mAh.Imagine a charger charging at 100mA for 16 hours, this would exceed the capacity of the Eneloop lite.

Yes, you can charge Eneloops with your (fill in brandname here) NiMH battery charger. This refers to the amount of energy (capacity/charge) that a batterycontains. JavaScript is disabled.

While the Panasonic BQ-CC55 charges 4 AA batteries in about 3 hours. Therefore it is better to use a .5C or 1C rate when using this algorithm. Start discharge directly after the charge has finished, without a break to 1.0V. It may be of some use to old batteries that are dying a slow death, but new batteries (especially LSD cells like Eneloop) should have no problem with just using the regular charge method regardless of how long it has been since they were last used. This will reduce their life cycle! The Japanese JIS 8708 Panasonic now uses is the same as the IEC 61951-2.Sanyo and Panasonic didn't make up some lousy numbers. Although constant current is used often for a longer period, they usually slow down when the battery is almost full. If cell drops below 1.0V during the 1-48th, the discharge may be terminated. Fortunately they use a rather low charge current and therefore won`t damage the batteries as much. At least for the break-in, it is highly advised to do a complete discharge first. This is a very basic way of looking at it. Ultra Fast chargersuse a very high current to charge your batteries. Some chargers like the Lacrosse BT C700 and Voltcraft IPC 1L have problems with refreshing Eneloop PRO batteries when set at 200 mA charge. When you charge the battery for 19 hours you will have 1900mAh charged. This is not true just by itself!

More on that in the Advanced charging section. The charger that uses a -dV/dt algorithm detects the battery is fully charged and terminates the charge. This is rather technical. Please look at theTests Pagefor the 5000 cycles test. The PanasonicBQ CC17 is also used by many but is quite a bit slower and older.

An Eneloop technician actually recommended charging with .5C - 1C. Check out themanual of your Eneloop chargerto know how long it can take. Can Eneloop batteries really be charged 2100 times? Cycle 2-48: charge at 0.25C for 3 hours and 10 minutes. Please go to theAdvanced sectionbelow to see how these tests are performed. This is a very handy feature when reviving older / often used batteries! And if you have anadvanced charger,you can set the speed by yourself. Maha PowerEx MH-C9000 Wizard One AA/AAA Battery Charger Analyzer + 4 Pack IMEDION AA Size Low-Discharge Batteries [2400mAh]. I wouldn't bother using the refresh/analyze/break-in stuff. If you have any suggestion or correction, post in the Comments section and I will try to incorporate it. Check out the list with the best and worst Eneloop chargers. They think that slow charging will result in longer cycle life. When 1 battery is charged for 50% and the other 3 to 100%, and you turn on the flashlight, the batteries will drain and the 50% charged battery will be empty before the others and the current keeps flowing through the battery which will damage this battery and increase itsinternal resistance. My advice would be to not use the Break-In mode (too often) with Eneloops, especially not with Eneloop Pro. My recommendations for manual chargers; (charge rate: 0.3C-1C). No, that is not necessary. See this graph that HKJ made and look at the Red line.

Just before it stops charging you can see it going down. So 19hours discharge at 100mAequals 1900mAh. What charger is recommended for Eneloops? What is a Refresh/Analyze mode with Eneloops? Break-in is not needed on LSD, unless if you want to accurately determine the overall capacity. Just keep in mind that Eneloops do not come from the factory fully charged. This is the problem! So at half the charge rate, it`s taking 2 hours to fill.

At this stage, the battery can only provide 60% of its capacity. Some chargers like the Panasonic BQ-CC16 and BQ-CC55 use a 1-hour trickle charge to top off the battery. mAis also used for thedischargecurrent. When you need to know more about the details.

Only with an empty battery! But every trustworthy battery manufacturer that uses these IEC or JIS standards has to follow these rules: Battery cycle testing is done insets of 50 cycles, with the following requirements: Cycle 1: charge at 0.1C for 16 hours. It is therefore always advised to use sets of batteries always together, andthe eneloop limited editions will greatly help to keep track of your sets. I wouldn't bother using the refresh/analyze/break-in stuff. Eneloops don`t really need it unless you want to have the extra 5+% capacity. 0.1C is 0.1 times the capacity. Also, since the batteries are used, they may be so tired that they can't be reconditioned. It is Panasonic's flagship. This is a common problem when using batteries in a multi-battery application. It all depends on how much you care about it. It really depends on how you charge them, and how much you discharge them and at what current. Dumb chargerscharge batteries for a set amount of hours. Duracell, Energizer and no-name. // As an Amazon Associate I earn from qualifying purchases. Or check outwhere to buy it. I also believe that they can be charged more than 2100 times. This function can be found on many more advanced battery chargers like the ones on the Advanced Charger page. 19hours of 100mA= 19*100=1900mAhThis is a simplified way of looking at it, but not really the way mAh actually works.

c9000 powerex maha lcd analyser sanyo eneloop seedcamera Wrong. (See the Advanced section for detailed information) This will limit charging related damage to a minimum.They also charge cells individually soyou can remove or add another battery during charging. 1.2 V is the typical voltage under load. Especially Eneloop PRO cells do not like to be charged hot. A 1900mAh battery can only hold 1900 mAh even if you put 2500mA into it. After the Discharge of every 50th cycle, it is allowed to stop the cycle test until a later time before continuing with the 51st cycle. You are using an out of date browser. Another difference is that my printed manual and the second PDF above say that refresh & analyze mode rests for two hours, while the first PDF above says it rests for one hour.

You check which Eneloops have the closest capacity and use those in an application to protect the batteries from an over-discharge / deep discharge. What does a 1C / .5C /0.1C charge rate mean?

Do I need to charge my new Eneloop batteries before I start using them? powerex c9000 charger mh battery aa analyzer maha aaa More about this in the Advanced section. Let`s go back to the first example. And discharge at 0.2C to 1V. helpful feedback charger powerex sending 1277 yes found

Try tocompare it with a 1-gallon jug. They tested them according to these standards. Have a look at all theproduct sheetson theoverview page. I had such instances of batteries falling due to break-in (which were good enough just prior the break-in) because they were not being fully discharged in my attempt to improve a bit their capacity.

This is used with charging Lithium-Ion batteries for example, so Panasonic NiMH chargers do not have this charge algorithm. This algorithm will charge a battery with a constant current that stays until the Constant Voltage is reached.
