So the continuation of the process may depend on the charger. 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). I also believe that they can be charged more than 2100 times.

But because of its array of functions, new users may be confused on how to fully make use of its power. So better set the charge rate at max, in this case, 700mA.

It really depends on how you charge them, and how much you discharge them and at what current. An Eneloop technician actually recommended charging with .5C - 1C. Imagine you would charge them twice every week for "just" 1000 times. What is the difference between mA and mAh? When both of these cycles have a smaller discharge duration of 3 hours the test is considered complete. powerex c9000 mh charger analyzing test Eneloop batteries can hold at least a charge for 10 years! What did you use your flashlight for today. A battery charger uses a charge current of 100mA. This means that the current will exceed the maximum charge current advised by Panasonic by about 2-3+ times. Eneloops don`t really need it unless you want to have the extra 5+% capacity. It is according IEC and JIS testing specifications. Isn`t that the same? This would imply that you do 25*100mA which would result in 2500mAh. powerex datasheet semiconductors Eneloop batteries can generally be charged with any kind of NiMH battery charger. You can use this method with all NiMH batteries, not just Eneloops. Group batteries with capacity within about +/- 5% of the rated capacity. This is the problem! Select the department you want to search in, Reviewed in the United States on July 18, 2012. is perhaps the most advanced battery charger/analyzer in consumer market. Or check outwhere to buy it. And if you have anadvanced charger,you can set the speed by yourself. For a simple charger, I would currently recommend thePanasonic BQ CC55 for Eneloop standard and PRO. At least for the break-in, it is highly advised to do a complete discharge first. More on that in the Advanced charging section. Can I refresh Eneloops if I don't have a charger with a refresh option? See the below picture from the Panasonic website.

Please look at the Eneloop battery charger overview page for more information on allchargers made by Sanyo and Panasonic. Start discharge directly after the charge has finished, without a break at 0.25C for 2 hours and 20 minutes. Hmm, most likely you won`t be able to do this. 2 Examples of the15-minute chargers which you should be staying away from or only need them in great great emergency.

Is it just trying to tell you the easiest way to do it, or is there some more serious effect? 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. 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. Can I use my (fill in brand) charger for Eneloops. They will charge the batteries for x amount of hours. Check out the list with the best and worst Eneloop chargers. Delta can be translated as a Change. I wouldn't bother using the refresh/analyze/break-in stuff. 0.1C is 0.1 times the capacity. 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. (see the Discharge Rate during the 50th cycle). Another way to remember it is to say, 0.5C is 0.5 times the capacity. Often they will only charge batteries in pairs. Start discharge directly after the charge has finished, without a break at 0.25C for 2 hours and 20 minutes. No, this has nothing to do with burglars nor with your breakfast. Refresh & Analyze will detect a full charge and terminate. What's the significance of how you insert the 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.

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. Please go to theAdvanced sectionbelow to see how these tests are performed. This is the total capacitythe batterycancontain. 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. No, definitely not. Because 5 times 20% equals 100%. Charging at a slow current can actually be more problematic when the charger can not detect whether a battery is full. At least for the break-in, it is highly advised to do a complete discharge first. These chargers can refresh your batteries, and check the capacity! 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 will normally boost the capacity back to its max capacity. Try tocompare it with a 1-gallon jug. Take a look at the following graph by HKJ. 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. 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.". Do whatever works for you. (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. And discharge at 0.2C to 1V. Cycle 49: charge at 0.25C for 3 hours and 10 minutes. When using rechargeable batteries in sets, the closer they are in capacity, the less likely that one will be driven into reverse charge. NiMH chargers don`t usually include this feature. You better use a flashlight with incandescent bulb because most modern LED flashlights have different built-in digital power circuitry which will all work differently and probably quit working before the batteries are completely discharged. Get one, and be happy for many, many years! At this stage, the battery can only provide 60% of its capacity. Wrong. If you have any suggestion or correction, post in the Comments section and I will try to incorporate it. Only with an empty battery! It`s a great feature for old rechargeable AA or AAA batteries that are almost useless or completely dead. So 19hours discharge at 100mAequals 1900mAh. How long will Eneloop batteries hold a charge? I usually recommend doing a refresh once or twice a year when you don`t use your Eneloops often.BTW you can repeat this Refresh mode if you're not satisfied with the results of the 1st Refresh cycle. . These 2 checks can be missed when the batteries are charged at low current! It is not mainly about the charge current butwhenthe charge stops. It might even be the wrong terminology as it is a fairly high Trickle chargeand sometimes people call it atop-off charge. So at half the charge rate, it`s taking 2 hours to fill. 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. The charger that uses a -dV/dt algorithm detects the battery is fully charged and terminates the charge. Give them a cup of water or even a lollypop will do. Well, you can compare 0.2C discharge rate with 20%. The life cycle test will stop when the battery can`t reach 60% of its original capacity during a 50th cycle-set. 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. The battery will take 19 hours to discharge the battery from 1900 till empty. Smart chargers can detect when a battery is fully charged and usually have a back-up cut-off usinga timer. When you continue throwing water into it, it will still only be 1 gallon of water inside the jug. Let`s take a standard Eneloop with a capacity of 1900mAh. Since the 2700s are not LSD, they are probably discharged already but I would run Refresh & Analyze first rather than Break-In. // As an Amazon Associate I earn from qualifying purchases. 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. mAis the unit (milli Ampere) used for thecharging current, which you can compareto"the speed of charging". It is also a much shorter cycle than Break-In so I would do it first before deciding whether Break-In is required. When you need to know more about the details. I wouldn't bother using the refresh/analyze/break-in stuff. Also notice that the black line, temperature rises at the same time, they go hand in hand. (However, this is different from a Refresh or Analyze mode)The Maha Powerex MH -C9000 for example has a Break-In option. So that means that my Eneloop batteries can`t be charged 2100 times? This is a very basic way of looking at it.

With aRefresh modethe charger will charge, discharge and then do a final charge to complete the cycle. It is Panasonic's flagship. When you empty the jug, only 1 gallon of water would come out.

Eneloop PRO will lose a charge quicker, but still only 15% within 1 year.

The package claims: Ready to use, and that is correct. Likely because it uses a lower current, to begin with. More about this in the Advanced section. The best and most advanced Eneloop charger currently available is the Panasonic BQ-CC65. The PanasonicBQ CC17 is also used by many but is quite a bit slower and older. Maha PowerEx MH-C9000 Wizard One AA/AAA Battery Charger Analyzer + 4 Pack IMEDION AA Size Low-Discharge Batteries [2400mAh]. They think that slow charging will result in longer cycle life. Should I discharge my Eneloops completely before charging them? What is the maximum charge voltage for Eneloops? My recommendations for manual chargers; (charge rate: 0.3C-1C). New Eneloop batteries need a few cycles to get to max capacity (This is also written in each battery product specifications. Discharged right out of their package! It may not display this or other websites correctly.

For a better experience, please enable JavaScript in your browser before proceeding. And you could do a refresh on a more advanced charger by setting the mA. Please take a look at this graph below that is taken from a 4th generation Eneloop standard product sheet. The cycles are counted until there is 60% capacity left from the original capacity when the test stops. 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. This is still not a recommended termination for NiMH. Why does my Eneloop charger stop charging at 1.6 Volts and sometimes at 1.45 V? It is only useful for ordinary NiMH cells that have been left in completely drained state for months. Cycle 2-48: charge at 0.25C for 3 hours and 10 minutes. 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. When the duration of the 50th discharge cycle becomes less than 3 hours, the discharge test has to be redone according to the specification of the 50th cycle.

The 0 dV refers to 0 Voltage difference at x amount of time. Eneloop AA batteries are mostly charged till about 1.5 or even 1.6V. You can charge Eneloops with any NiMH charger.

Some advanced chargers will continue this cycle until the max capacity is reached. Check out more info on the PanasonicBQ-CC65. This list is work in progress. I get this question asked a lot. They put their Eneloop Pros in a time based charger and think they are treating their batteries nicely.

Please look at theTests Pagefor the 5000 cycles test. There you will see the fast charge current. It`s better not to charge at a very low current becauseit is more difficult for the charger to recognize if a battery is full. What does this mean -- ( MAX( actual_capacities ) - MIN( actual_capacities ) ) <= ( 2700 * 0.05 )? They can be charged in your average Eneloop charger unless the charge current is too high. 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. 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. A 1900mAh battery can only hold 1900 mAh even if you put 2500mA into it. Do Eneloop Lite batteries need a special charger? This is rather technical. Disabling it will result in some disabled or missing features. Just before it stops charging you can see it going down. Although constant current is used often for a longer period, they usually slow down when the battery is almost full. This is great for people who don`t want to wait for a long time and want a clear indicator that batteries are charging, or full.
