Batteries batteries batteries!

I got these about three weeks ago and still haven't used them up yet. So many batteries. Awesome. So far they've lasted about four times as long in my Canon digital point-and-shoot than my Energizer rechargeables. And they're on track to outperform the regular Energizers in my Xbox controllers. I think I'm a coppertop convert. The price is pretty good too--probably not the absolute cheapest but these are real Duracells (not knockoffs) that are far from their expiration date.More detail ...

LSD is great.... just keep away from heat!

According to Sanyo the new eneloop LSD (low self-discharge) NiMH batteries can maintain 85% of its original charge after 1 year of storage. This claim is slightly misleading because it is based on simulation test at 20 degree C. At higher temperature the self-discharge rate is likely to be much higher.



I have tested five of those AA cells (details are given in my review for the eneloop 4-pack). The average energy loss is about 26% after less than 6 months of storage based on manufacturer date codes. This self-discharge rate is about 3 times higher than what Sanyo claimed. However it is still 6 times lower than that of ordinary NiMH batteries. Therefore I'm in the process of replacing most of my existing rechargeable cells to the Sanyo eneloop.



Thanks to lower self-discharge rate you'll discover a lot more applications for eneloop cells in your house such as in clocks and remote controls. Do NOT use those cell in smoke detectors since their discharge voltage profile is very different from that of alkaline cells. Also don't use them as emergency flash lights batteries in your car because the higher temperature during summer time will probably nullify the advantage of LSD.



[Update on Jan 13 2007]

I have tested six new eneloop AAA cells dated "2006-06'. The average residue charge is 589mAh and the freshly charged capacity is 827mAh. This implies a self-discharge rate of 29% in 7 months which is consistent with the rate for AA cells (26% loss in 6 months).



[Update on Jan 29 2007]

The Rayovac "Hybrid" rechargeable NiMH batteries are now available at Walmart priced at only $[...] for 4-pack of AA or AAA cells. It is also advertised to have low self-discharge rate but not as low as that for eneloop. The eneloop is supposed to retain 85% charge in 12 months (when stored at 20 degree C) whereas Hybrid is supposed to retain 80% charge in 6 months (no mention of temperature).



[Update on June 3 2007]

In my 2-month self-discharge test using four different brands of NiMH cells. Hybrid and eneloop came up neck-and-neck!



Room temperature: 60-62 degree F (16-17 degree C). All capacities measured are average of 2-cells.



- Sanyo eneloop 2000 purchased Jan 2007.

Initial capacity measured: 2070mAh

Capacity after 62 days: 1796mAh (-13.2%)

(Note: my previous result for eneloop showed -18% but I repeated the test and it did better this time)



- Rayovac Hybrid 2100 purchased Jan 2007.

Initial capacity measured: 2155mAh

Capacity after 62 days: 1859mAh (-13.8%)



- LaCrosse 2000 purchased Jan 2006.

Initial capacity measured: 1902mAh

Capacity after 62 days: 1417mAh (-26%)



- SONY 2300 purchased Sep 2004.

Initial capacity measured: 2210mAh

Capacity after 62 days: 1309mAh (-41%)



So neither eneloop nor Hybrid did as well as advertised but they are still significantly better than previous generation of NiMH cells. So you can't go wrong with either brand.

All they are supposed to be plus a couple of mAh's

OK. So notice most of the complaints are about the shipping time not the quality of the product.



Ordered 3/26 received in two days with prime.



As others have mentioned these are 900mAh batteries.



Ran the 4 cells through a few charge-discharge cycles on a BC-900 charger (also a good product available here). All of the batteries tested above 900mAh. 902 926 928 and 937mAh. This is with only a few cycles on them so it might creep up later but should not be much.



This is better performance than less expensive brands (ultralast etc.) Those seem to test at only about 50% of the cells above the stated capacity although they are often at least 85% of listed capacity.



Just my experience with a small sample size. Choose which is best for you.



Would be 5 stars but could be a bit less expensive. Only a minor complaint.



Update 8/2/06



Used these in a GPS unit and MP3 Player mainly. Probably have been recharged around 10x each. Retested now they are at 900 924 930 and 932. so not much change

Great value batteries that perform as well as leading brands

We go through plenty of batteries at our house. These Rayovac batteries are a great value. They perform as well as the other leading brands and are significantly cheaper especially if you order from Amazon and opt for free shipping. We'll buy more of these and other sizes of the same product.More detail ...

love these things!!!

these batteries are great!! use them up pop them in the charger and 15 minutes later we are rolling again...this is a major plus with my daughters numerous electronic toys and my remotes. too bad i cant find these at the local stores anymore. fast shipping too.More detail ...
