I tested four of those cells, using my old La Crosse BC-900 Battery Charger.
- Right out of the package, their average remaining charge is 1568mAh, or nearly 80% of the rated capacity of 2000mAh. The spread is also very small, from 1558 to 1577mAh. This proves that they are indeed low-self-discharge type. (Date code on my cells says "11-01", or Jan 2011)
- After one recharge/discharge cycle, their average capacity improved to 2115mAh
- After two more recharge/discharge cycles, their average capacity leveled off at 2133mAh, or more than 6% higher than the rated capacity.
The above results are very consistent with what I have previously observed, while testing second-gen eneloop cells in the Costco package.Read more ›
[Q1] My Sanyo eneloop AA batteries say '1900mAh' on them. Are they counterfeits?
[A] All eneloop AA cells (both original and second-gen versions) are rated for "Typ 2000mAh, Min 1900mAh" according to Sanyo. The confusing part is that 2nd-gen eneloop AA cell only has "Min 1900mAh" printed on it, even though the actual measured capacity is close to 2100mAh.
Simialrily, eneloop AAA cells are rated for "Typ 800mAh, Min 750mAh".
[Q2] Date code on my new eneloop cells says '10 01' (Jan 2010). Should I exchange them for newer batteries?
[A] Relax! Unlike ordinary NiMH cells, Sanyo eneloop are still perfectly good even after 5 years in storage. Once you recharge them, they will return to 100% capacity again.
[Q3] What is the difference between 'Pre-Charged', 'Hybrid', 'Stay-Charged', 'Active Charged', 'Ready to Use' and 'Ready to Go'?
[A] Those are all marketing terms for Low-Self-Discharge (LSD) NiMH batteries. Sanyo first used the term 'Pre-Charged' for Sanyo eneloop back in 2006. Rayovac used 'Hybrid', and so on.
[Q4] I just received some new eneloop batteries. Do I need to recharge them before use?
[A] You can use them right out of the package. However, eneloop cells are only charge up to ~75% when they left factory. So you can use a Smart charger to 'top-off' their charges. Do NOT do this with a Dumb charger because it will badly over-charge them.Read more ›
- Right out of the package, the average remaining charge is 640mAh, or 80% of the rated capacity (800mAh)
- After the first recharge cycle, the average capacity increased to 839mAh.
- After two more recharge/discharge cycles, the average capacity leveled off at 843mAh, or 5% higher than rated capacity.
The above is very consistent with the results I obtained last year, while testing 2nd-gen eneloop AAA cells from the Costco package. Therefore I have no doubt that those batteries are genuine. Date code embossed on them says "10-12", which means Dec 2010 (see my upload in the "Customer Images" section, if you need to know where to find the date code).
According to Sanyo press releases, those 2nd-generation eneloop cells offer several benefits over the original eneloop:
- Can be recharged "up to 1500 cycles" (vs. "1000 cycles" for the original)
- Can hold "75% charge after 3 years" (vs. "80% after 2 years")
- Works down to -20 degree C (vs.Read more ›
