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.

I would have thought that rec.photo.digital was the better group until a
..batteries group was created!

I think you have simply been unfortunate. 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.

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.

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

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

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!

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

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.

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.

Roger, I still see a lot of posts on rec.photo.digital. There were 180 of
them just this afternoon.

Actually he/me/I is talking about AA cell lifetime in cameras which
would also include many of the 35 mm cameras as well. <:-))

Nope , I'm gonna take my marbles home and go play<:-))

Actually, can any of you still get RPD? It is no longer on either
server I use.

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.

I do.

The four new groups are still not on quite a few major servers, so give it
time. Don't expect the traffic in any of the four new groups to get as
heavy as RPD. Instead, expect lower volume targeted traffic in each group.
It takes a long time for the chips to fall after new groups are created.
Three out of the four new groups are actually doing very well for groups
less than a month old.

I see that you use Supernews. They still carry RPD. RPD was not scheduled
to be removed as part of the reorganization. Maybe you need to refresh your
groups list. If it is still a problem, contact support [at] supernews dot
com.

That was one of the first things I tried.
I lost two groups just after the first of the month when I changed
from DSL to cable. I was still using the same settings and the groups
were missing from OE as well as Agent. It showed as subscribed, but
refreshing did not find RPD. I then switched to the cable's
newsgroup, SuperNews. Still the same thing.

After trying numerous routes I finally ended up unsubscribing from the
two groups, shutting down and restarting Agent, "then" refreshing the
newsgroups and RPD was there. Then resubscribing.

The same route was necessary in OE.

Something had to have changed in the reader(s), but the confusing part
is "both readers"?

Yes, I have multiple firewalls and my computers check clean.

At any rate I can again read RPD.

The great 'dedicated' battery rip-off is why I'm seriously considering the
new Pentax *ist DS - uses AA's.

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 .

Hi All:


Some points about Lithium cells.
Lithium cells are very different from NiCad or NiMH cells.

1- Lithium batteries have a shelf life, they will go bad wither they are
used or not. How long the shelf life is depends on the manufacture and the
design of the batteries. This is a good reason not to buy used or old
lithium batteries.

2- Lithium batteries have a limit on of the number of times they can be
completely discharged and re-charged. This is about 500 to 1000 times
depending on the manufacture and the design of the cell. Un-necessarily
completely discharging a Lithium battery wastes life of the battery.

3- Lithium do not have any memory effect. In fact the best way to extend the
life of the cell to the maximum the self life will allow is to keep them
fully charged. It is best to keep them in the charger and fully charged.
Lithium batteries in the proper charger can not be over charged.

4- Charging a lithium battery in a charger not designed for that battery
risks a fire. Without proper charging lithium batteries can explode or burn
up.

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 .....

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.

Good thread. I just got a 20d and was wondering if i should buy a 2nd
battery. The aging issue concerns me. I don't suppose theres really
any way to forestall that. It seems to charge pretty quickly and i
keep a power converter in the car to plug into the lighter and
recharge while to - and -fro.

Always carry a spare battery. If the charge runs out while you are
shooting you won't have time to recharge.
