To clarify, there are now three different versions of AmazonBasic rechargeable NiMH batteries:
- The original AmazonBasics batteries came in black wrappers. They are made in China and have the capacity rating of 2000mAh. They are NOT as good as Sanyo eneloop batteries.
[[ASIN:B0030T1NEA AmazonBasics AA NiMH Pre-Charged Rechargeable Batteries]]
- The second version of AmazonBasics batteries came in white wrappers. They are made in Japan and also have the capacity rating of 2000mAh. They are (according to me) rebranded 2nd-gen Sanyo eneloop, so you can expect at least 1500 cycles lifespan.
[[ASIN:B00CWNMV4G AmazonBasics Pre-Charged Rechargeable Batteries]]
- The third version is also black but called 'high-capacity'. They are (according to me) rebranded Sanyo XX. They are rated 2400mAh, but actual capacity is around 2550mAh, just like Sanyo XX. The rated lifespan of the XX is only 500 cycles.

I checked the IR of these cells and with my Turbo Matched 30 from Competition Electronics (these are a 1500 dollar cell matching system that we professional RC on road and off road car and truck guys used to match cells. Very important and HIGH TECH for the time system. Was made for Nicd cells but worked equally well on Nimh cells when they came out) and matched them to get well matched pairs for practice cells for Mod Mini Z cars and boats.. I used Enloop cells for race days and practice with these.. these cells give a solid 2050 to 2100mah handle, will give me long run times and with cells matched with a 6 amp discharge will give me a avg voltage of about 1.02v per cell over 25 minutes, my well massaged Eneloop 2kMah cells i match at 8.5 amps they give me a avg May of 1980 to 2020mah and will hold a avg Voltage of 1.06V per cell at 8.5 amp load over 25 minutes.

Point is these cells are a very good value, even in high load usage these cells stand up a lot better then similarly priced Nimhs from other brands.. these cells offer 85% the performance of Eneloop at less then half the cost.. the cells hold up well until about 200 cycles then they deff start to have noticablly lower avg voltage over time at the same discharge curve.. but that's in higher load apps then most people will be using them for.. I charge these cells at .75C or 1.5 amps, at 1.5 amps the cells are slightly warm off the charger and that's how I want them, slightly warm when ready to run as the IR will be lower with a warm cell over a room temp one giving me less voltage sag as the cell warms up under load...

These cells will be slightly above ambient temp of charged at .5C or 1 amp, the warmth will start to happen once the cell reaches about 90^% full charge and progressively get warmer until peak charge.. at .75C charge or 1.5 amps you will notice the cells are a fair bit warmer then ambient temp and this has it's use for high load apps like my Mini Z's and some times I'll even charge them at 1C or 2 amps.. that will make for a fairly hot pack BUT will give me the highest voltage under load for the first 25 to 30% of the charge... but will ABSOLUTELY shorten the cells life and I would not recommend doing that UNLESS you know what you are doing to the cell and understand the cells life will be cut by good bit.. meaning if I get 200 really good cycles on a set of cells when charging them at .75C or 1.5 amps, moving to a 1C or 2 amp charge will know it's really good cycles life down to 100 to 125... but you will have less voltage sag/higher voltage under load taking the very warm cells off the charger and straight to using them then if you was to charge them at a lower rate and have cooler cells...

Charge at 1 amp and you will be happy with these cells .5C and under will give you the longest cell life for sure.. see less

Absolutely. The AmazonBasic (white) pre-charged NiMH cells are identical to the Sanyo eneloop cells electrically, so the charger won't know the difference.

The AmazonBasic (white) pre-charged NiMH cells are identical to the Sanyo eneloop cells electrically, so the charger won't know the difference. In fact, you can use any good-quality 'smart' charger designed for NiMH cells to recharge any brands of NiMH cells. Battery manufacturers always tell you to use only their own brand of charger - for obvious reason.
One inexpensive but Smart charger I often recommend is the [[ASIN:B003GS6FIE Sony Cycle Energy BCG34HLD]]. It can recharge each cell individually, which is much better than the [[ASIN:B002TZUB12 Sanyo MQN06 charger]] and [[ASIN:B004NSUMTO AmazonBasics NiMH Charger]] see less

Answer:
They are both advertised as 'pre-charged' and have the same capacity ratings. However, the white version is made in Japan and appears to be rebranded 2nd-gen Sanyo eneloop. The black version is made in China by some unknown manufacturer, and its charge-retention rate is not as good as that of the Sanyo eneloop.

Answer:
Carefully check that your Duracell charger is not for NiCd batteries. It must say that it will charge Ni-MH batteries instead. They are not interchangeable.

Answer:
"Memory effect" is commonly used to describe the drop in capacity in NiCd cells due to shallow discharge cycles. It does not apply to NiMH cells, especially not to low-self-discharge ('Pre-Charged') NiMH cells.
In real life both NiCd and NiMH cells often drop in capacity with time, but mostly due to over-charging or ov… see more

Answer:
AmazonBasics Pre-Charged batteries can be recharged using any good-quality Smart charger designed for NiMH cells. But for longer battery lifespan, avoid ultra-fast (15- or 30-minute) chargers and Dumb (overnight) slow chargers.

One inexpensive but Smart charger I often recommend is the [[ASIN:B003GS6FIE Sony Cycle Energy BCG34HLD]]. It can recharge each cell individually, which is much better than the official [[ASIN:B004NSUMTO AmazonBasics NiMH Charger]]
[Update on July 27, 2017]
The Sony charger I mentioned above is discontinued. I now recommend using the Panasonic eneloop chargers, either BQ-CC17 (slow) or BQ-CC55 (fast)
