NiMH Battery and Rechargeable Battery Review site

[guybon63bob]

I was looking for a good NiMH rechargeable battery for my player.

I found this site that some of you might find helpful.

Pretty nice..

I use a lot of rechargeable batteries, and during the last months I have replaced all my conventional NIMH-batteries with the new Sanyo Eneloop rechargeables. Their rate of self-discharge is negligible - now I can charge a whole bunch of them at once and use them weeks later when I need them.

The old NIMHs would often have discharged significantly by the time I needed them, which meant that I was always recharging them just in case and keeping track of how long ago they had been charged, and usually I carried one or two non-rechargeable batteries as a backup. The Eneloops are far more convenient for me, but I will have to see how well they hold up in the long term.

They sound intriguing - sadly they do not seem to be available in the UK at all! (we're always last for anything and everything!)

They do look nice, sadly the US chargers won't work in the UK I doubt...Still the batteries themselves should be fine in a conventional recharger, right?

So, have they been holding up alright, how do they compare to normal NIMH and are they worth a buy? (eBay and Amazon USA have them listed )...

I sure hope so, I have been using them with my old charger, no problems so far.

For me they are great, but it will depend on the intended usage. The AA-version has 2000mAh, whereas regular NIMHs are available with up to 2700mAh, I believe, so if you need a lot of capacity right now, then the latter will be the better choice.

The Eneloops are also weird in that they keep their voltage on the same high level for most of their run-time, whereas non-rechargeables and NIMHs tend to drop slowly. This can have negative and positive effects. For example, battery level meters in gadgets measure this voltage drop, so they get "confused" by the Eneloops - my T10 shows the battery as full or almost full for many days, and then it suddenly drops down to empty in a very short time. On the other hand, some tools (many flashlights, or my battery-operated travel shaver) need a certain level of voltage to operate well. With the Eneloops they work fine until batteries are empty; with other batteries the tool gets dimmer/slower all the time while the voltage drops, and it is useless long before the batteries are actually empty.
