Battery life.
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.

Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com . Interesting. I've yet to find a digicam that draws much less than ½ amp with the display on. Even my tiny Dimage-X pulls 400+ mA, but only about 6 mA with the display off, so the current delivering ability of a battery of whatever type is all important. I've found the big battery killer is overcharging. The practice of "topping up" a full battery before a shooting session can be B A D ! Most chargers doing this won't sense an overcharge before some electrolyte is destroyed, leading to a battery with apparent full capacity, but reduced current ability. Of course charging from flat allows the better chargers to predict the end point and stop in time. I agree that the cost of NiMH cells is low enough that the life is acceptable, provided you have a spare set for when the inevitable happens and a fully charged set fails in camera. The Lithium ion type can have exactly the same vulnerabilities, and they are expensive |

About two years with moderate to high use has been my experience with Li-ion batteries for Canon's D60 and 10D.

Proprietary batteries are a curse - whether they are for laptops, video cameras, or still cameras. Full marks to Pentax for building a camera that uses an inexpensive future-proof power source. |

Hi all
As a point of interest the guy in Jessops (Canterbury) also said that topping up was a bad idea until the batteries had been conditioned. Ths entails fully chaging then fully discahrging them 4 times. Discharge them by normal use and dont force the issue by up loading vast amounts of data to your PC - no topping up charges in this time . This is supposed to considerably extend the useful life of batteries . Keith M "Roger" wrote in message ... I cross posted this to the 4 digital groups as it pertains to all.

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...

A bit irritating considering their price... 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. -- Michael Meissner email: http://www.the-meissners.org |

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. MTB "Michael Meissner" wrote in message ...
