Duracell Pre Charged Rechargeable Nimh AAA Batteries, 4-Pack

These batteries are great. They hold their charge up to a year and they perform well in high drain devices. My one gripe is the price. I am not sure they really save people much money considering that they only last about three years total and regular AAA bats are soooo much less expensive.

Pros:
-For a rechargeable battery, these batteries does not need to be charged before you use it for the first time; right from the packaging into your gadgets.
-They last a long time. I use it on my portable speakers which has been playing in loud volume for many weeks.
-Does not need special charger. You can use your existing NiMh charger.

Cons:
-Just like what NLee mentioned (above). You can confuse them with regular Duracells and mistakenly thrown away after losing charge.
-This later technology is still expensive. I got them on sale from Safeway for 11$ Normally sold at 14.99$

I also like Eneloops by Sanyo. But they are not easily available at your local stores.

My husband is using these batteries on his model train remotes. He says they last very long before having to be recharged. Longer than regular rechargeable batteries.

Judging from similarity of technical specifications and physical shapes of (+) and (-) terminals, I am convinced that the Duracell Pre Charged NiMH cell is actually Sanyo Eneloop underneath a different wrapper. Therefore all the good things you heard about eneloop apply to Duracell 'Pre Charged', too.

My own testing has shown that the capacity of eneloop AAA cell is slightly above the claimed 800mAh. The Rayovac Hybrid AAA is usually cheaper, but its capacity is slighty below 800mAh. Both brands are able to retain at least 85% of their charge after three months of storage. Just pick whichever brand is on-sale, and you can't go wrong.

One small problem with the Duracell 'Pre Charged' cell is that: it looked too similar to the well-known 'Copper Top' alkaline cell. So there is a good chance that people may mistaken it for a disposable cell. Personally, I prefer the distinctive-looking white case of the eneloop cell.

These batteries are great. The new 'precharged' technology is great where it can sit unused for a year and still have most of its charge unlike the older rechargeable technologies. These 800 mAh actually last longer in my noise canceling headphones then the 1000 mAh (non-precharged) of the same brand.

I had previously purchased Energizer rechargeable batteries and found that after only a couple of weeks of non-use they would be dead.. so every time you went to use them they would be useless. After getting these Duracells and also some PowerEx batteries, I realize that the Energizer batteries are cheap Chinese junk. oh, the duracells are made in Japan and are very nice quality.

Anyway I definatly would recommend the precharged Duracells to anyone.
