I just recently bought myself a new digital camera, as my old one was
eating batteries. The new one worked fine for about a month or so of
occasional use, and then when the batteries that shipped with it wore
out I replaced them with a pair of Energizer NiMH rechargeables that had
been sitting on a charger in my room for about the same amount of time
(since I'd moved, anyway) my new camera is saying "battery depleted"
now which makes me think maybe old camera is actually OK (I stopped
using it because it would kill the batteries after only 3-4 pictures)
and just my batteries are Tango Uniform. But they are only maybe a year
old, what gives? Are alkalines really my only choice here? they don't
last very long in a digicam...
replace "fly" with "com" to reply.
I'd try another set of energizer NiMH AA's. I have 2 sets for my
digicam (3-yr old Canon PowerShot, takes 4xAA batts), and it easily
gets 200-300 shots per battery charge. I just use the charger that
came with the batts.
There are now several brands that advertise 2500 mAh AA batteries
(Energizer, Sony, and other well-known names), and I think ours are
2000 or less, so the new ones should theoretically be even better.
As far as I know, basically all the decent chargers now are "smart" so
you should be able to leave the batts on without a problem.
You might also try contacting the camera manufacturer - my uncle had an
older Kodak camera that went through batteries after just a couple
shots, got it replaced twice, and finally got one that had reasonable
It seems that all the cameras eat batteries. There is some good detail
about both batteries and chargers in the informative article found
I hope that helps and I'm sure Google can find similar test results and
NiMH can be recharged thousands of times but apparently slowly
discharge at maybe 1% a day. If camera sits around for a couple of
months, it is best to recharge batteries before use. As other poster
said, these cameras eat batteries, so NiMH use is still best bet.
And the best thing is that they are standard size batteries. If you ever
forget to take spares, or use up all the ones you have, you can put in some
AAs and keep taking pictures.
We recently went to Mazatlan with another couple. He brought his new Nikon.
He forgot to bring his charger. He could not find a new battery, nor a
charger, and if he did, they would have been $50 each or more.
I also use the AAs in my GPS unit. It is nice to have gear that takes all
the same size batteries. One of my chargers works in the car, too.
Looking over my Monster battery literature, they say 1 to 2% loss of
charge per day and batteries can be recharged over a thousand times.
NiCads are different and as someone pointed out, voltage potential
varies with the electrochemical potential. I don't use rechargables in
my Etrex gps as it is not often used but when I need it, I want it to
If your Energizer batteries are made in Japan, it is a quality issue with
that particular source. This is widely known on the digital camera
newsgroups - a place where you can get more focused answers on digicams
than a newsgroup devoted to home repair.
Try a different brand.
I think they all suck, in terms of how they perform, and they all seem to
lose charge in storage. Based on recommendations from a group of people who
use them in handheld devices OTHER than cameras, I tried Panasonic
rechargables, and they're somewhat less disappointing than others. However,
as someone else mentioned, cameras seem to be more demanding than, say, a
handheld VHF radio or GPS toy.
My old rechargeable batteries are just that, old. They
no longer hold a charge as long as they should. It is
just the way they work.
One thing about rechargeable batteryies. The starting
voltage is not as high on the NiMH batteries as the
regular alkalines. So they seem to run down a lot
And beyond that I have started using Energizer E2
batteries. The set I put in the end of October
are still showing above 65% charge and I have been
through 2 parades and a fireworks display with them.
They have a very good life in cameras.
Some digital cameras do not recommend using alkaline batteries.
The reason being that these cameras draw so much current that
the alkaline's voltage dips below the nominal voltage of the NIMH
Some cameras do not recommend Lithium batteries. The Lithium E2
battery supplies to much current at a higher voltage than the nominal
voltage of the NIMH reference.
Read the manufacturers manual on what batteries can be used and what
to expect from them. Use Eneloop if you can find them.
I gave up on rechargables for cameras. They always seemed to self discharge
when ever I needed to take a picture. Alkalines can't meet deep current
requirements a camera has. I finally settled on a pair of Everready
photolithiums. approx $10 for 4. They don't self discharge and are always
ready for that unexpected picture. I still use rechargables when I expect to
use the camera but between events the camera is loaded with the
photolithiums so its always ready for that unexpected picture.
Note: It is always good practise when charging rechargable batteries to take
them out of the charger as soon as they are charged. Letting them sit in the
charger will cook them and shorten their life.
NiMH chargers are either electronically timed, for a specific capacity
battery(5 hrs. for a 1600 mah, eg.), or as in the case with most newer
chargers for sale now, automatic. No need to unplug or remove. Both
styles have indicator LED's to show if charging is taking place. The
timer type WILL reset & charge again after a power interruption, so be
aware of that.
As a youngster, we had a "Federal" 4-bay battery charger that we used to
charge hundreds & hundreds of carbon-zinc batteries over the years( for
Motorific cars & Hot Wheels "Superchargers, etc.). Many years later I
took it apart to see how it worked, it was a just a rectifier & a
special compensating bulb in series with the 120v mains! I'm surprised
we never burnt down the house or had any acid mishaps the way we used to
cook 'em to get a good charge!
Go to any big box store and you can buy the charger and four batteries for
about $15. They have the brand names. They have off brands. Buy the ones
with the highest number capacity, as they last the longest.
Main thing is not to leave them on the charger, which I believe you did. I
have heard of them catching fire when left on a charger for a long time.
Bottom line, I have several brand names. I have about twenty batteries,
total, and I also have AAA that I use in my walkie talkies. You can buy
such a thing as a "smart charger" and that senses the level of each battery
and charges it accordingly. They are around $40.
Rechargeable nimh batteries are good. They will save you money. They do
have to be used properly, though.
That can only happen if the charger is broken. A properly functioning charger
will shut off when finished and perhaps run a minute trickle afterwards to
keep the batteries from self discharging.
What I've observed over the last three decades is that rechargeables will last
nearly forever as long as they are kept in regular service. Quit using the
walkman/camera/whatever and leave the batteries in a drawer for four months
and they'll be ruined.
Many chargers are of poor quality. The good ones charge each battery
independently. Assuming you are using AA batteries and you don't have a
charger that indicates when each cell is done, I suggest a new charger.
