Battery life.

My 2 & 1/2 year old Lithium Ion batteries..original Canon G2 batteries, are
on their last legs.... I can coax about 100 shots on a full charge..vs 300
shots when they were new. A bit irritating considering their price...
Another good website about batteries is .....

I cross posted this to the 4 digital groups as it pertains to all.

It's been about 2 1/2 years since I went digital, first with the Oly
E20-N and now the Nikon D-70.

I started out with two sets of AA NiMH batteries and added a third.
One set consisted of 8 2000 MAh batteries, one set of 4 1800 MAh,
batteries and one set of 4 1850 MAh batteries.

One of the early 2000 MAh batteries failed early on. Not too long ago
a second failed. In the last week I had one fail in each of the other
two batches.

They were heavily used at first, but since the D-70 have received only
occasional use. They have been conditioned twice in the last year.

I didn't name any brands as the failures seem to be pretty well
distributed between on and off brands.

Considering the cost of NiMH batteries, I think I ended up with
reasonable life out of them.

Likewise the rechargeable Lithiums are rated with both a cycle life
and calendar life. The proprietary battery with the D-70 seems to
have tremendous capacity, or longevity, but it's life is still rated
in the neighborhood of two years.

Generally Li-on batteries last about 2 years after manufacture before they
start degrading, so it sounds about normal. Unfortunately if the manufacturer
of your camera didn't use a standard battery type, it may be expensive to
replace the battery after the model is no longer sold.

I got lucky here... the battery used in the G6 will work in my G2, so I'll
probably get one soon...a battery that is...not sure if I'll get the G6.

Canon generally tries to reuse the same battery across generations, but not
every company does so.

As this thread is of general interest, it might be better being in just
rec.photo.digital, rather than in the four new group. Please consider
trimming the cross-posting accordingly.
