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.

We mus have bought a dozen or more sets of 4 and only had two fail. There were DOA and replaced by the shop. NiMH cells don't have the same limited shelf-life that Li-ion cells do. Cheers, David |

LOL. Actually, he mentioned batteries for both a ZLR (E20) and an SLR (D70) so his post falls within the on-topic bounds of the ZLR and SLR-Systems groups, but was totally off-topic for the rangefinder and p&s groups. -- Bill |

LOL, indeed! I do think a single posting in rpd would have been more appropriate, rather than creating a fragmented discussion, though. David |

Agreed, but I can understand the initial confusion until the chips finish falling. When in doubt..post to rec.photo.digital, or at least set follow- ups there if you feel the need to crosspost. To the OP..we're not netcopping you. Stick around! -- Bill |

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.

We mus have bought a dozen or Actually, I thought I was doing quite well. 2 to 2 1/2 years is about the time I figure I'm going to pitch the rechargeable and replace them. more sets of 4 and only had two fail. There were DOA and replaced by the shop. NiMH cells don't have the same limited shelf-life that Li-ion cells do. Having used NiMH batteries for some years in Hand Held radios (244 and 440 MHz ham rigs) I've found that the ultimate life of the NiMH in years runs pretty close to, or only slightly better than that of NiCads that in turn seems to be about what they advertise for Li-ion rechargeable. All three "from my limited experience" run two to three years. With either I figure I'm going to be doing a major replacement every couple of years. When it comes to the number of shots per battery/batter pack they all seem to work out about the same cost.

Actually he/me/I is talking about AA cell lifetime in cameras which would also include many of the 35 mm cameras as well. :-)) Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com |

OTOH, I think this thread has already developed more traffic than I've seen in a week on the 4 digital groups. OK, not quite, but I'm not seeing much.
