"Eneloop" batteries vs. other NiMH ?

Posted by pogo on August 4, 2008, 5:06 pm

Any comments on the new "Eneloop" batteries by Sanyo ? I saw some in Costco
today, but noticed the sales blurbage only talked
about Eneloop vs. alkaline cells, not other NiMH batteries ?

Any opinions based on experience/knowledge ?

I have a set, but I have barely used them yet, so I can't comment on
how well they actually work.

The point with them is their very slow self-discharge rate. This comes
at the expense of a somewhat lower capacity, compared to other NiMH
batteries.

I have put mine in my digital camera, which may spend weeks or months
without use, before it suddenly has to be ready to go.

Eneloop IS NiMH, so the comparison is fairly moot.

What differentiates these cells is that they have additional engineering
properties of low self-discharge, so they are able to reliably ship them
already charged.

My guess is that Sanyo saw an opportunity to enhance rechargeable sales
by offering a battery already charged, and therefore something for
impulse buying and use. Like next Christmas when Johnny gets a new toy
robot. I have to say that's about the only reason I keep alkalines
around. I often don't have the time to wait for batteries to
charge/recharge.

Hmmmm - so we're just basically paying for having them delivered pre-charged ?
Unless they charge faster than other NiMH --- now
*that* is a feature I would pay extra for ...

I didn't notice that they cost all that much more. In any case, the
pre-charge is just a by-product of a battery that keeps its charge for
longer. If you're paying anything extra at all, it's for that. It's
handy not to have to keep topping off your rechargeable batteries.
