Power drain? I take a few pictures with fully charged Quantaray 1.25 V, 2650 mAh batteries. I turn the camera off and a few hours later when I turn it on again, it tells me that the batteries are depleted. Very frustrated, Jeff K. Stuart, FL

Olympus Camedia E10 won't power on with AA NI-MH batteries but works fine with AA ALKALINE, what can I do?

Always charge batteries before using it for the first time, or if you have not used it for a long period. 3 months is a very long period.
Always charge sets of batteries (2 or 4) together.

Make sure your rechargeable batteries are all good. One defect in a set is killing for the whole set
Don't use barrettes from different sets or brands together.
I had one brand good NiMH batteries and a very expensive charger from the same brand. The charger destroyed all my rechargeable (more than 60 now). When I first discovered the batteries were dropping out, I stopped using the charger, but it did not prevent all batteries to die in the following months. Every time on dropped out I had to change the set. I tried using up the others by grouping the ones with the same Ri, but not longer then a few months and I had a box full to trow away.
Never use a quick charger, capable of charging them within an hour or faster. Us a charger that indicates the Ri is still low enough, so you can see what batteries are bad.
Check you are using a charger for NiMH batteries.
I would try another set (new) because buying Alkaline is also not cheap.
I used 2700 mAh and later 2600 mAh rechargeable, all dead now. since a few weeks I'm now using 2300 mHh from another brand, costing 1/5 of the "best" I had before, and they are doing great. I won't charge them with the quick charger.

Never use manganese (Zinc-Carbon) batteries in electronic devices.
These batteries are only to be used in flash lights.

Can 1.2Vlt 800 mAh battery 1.2 volts instead of 630 mAh battery used in this device? ..

There should be no problem at all. The designations you show are both for 1.2 volts. The mAh specification refers purely to the capability of the rechargeable to deliver current over a period of time. 800 mAh will deliver 800mA for 1 hour or 400mA for 2 hours. Hence the 630mAh battery under fully charged condition will not last as long as the fully charged 800mAh battery when supplying the same current in the same application.
Hope this is helpful, if so would you please register that with Fixya

Just bought a second hand Canon Powershot SX100 IS.

Try cleaning the battery contacts in the camera first with a pencil eraser and then with a cotton swab lightly dampened with rubbing alcohol.

I just got my camra a few days ago and i put new batteries in then 1 day later i had to put new ones in, then i take about 2 or 3 pics and my camra turns off on its own...what is wrong with it?

Are you still using alkaline batteries? If so, alkaline batteries just don't have the power for more than a few pictures in a digital camera. Some may also have reached their shelf life, and though right out of the package may even have problems just powering startup of the camera. Digital cameras that use AA's for the most part should only be used with rechargeable NiMH batteries. If you read the camera's instruction manual concerning batteries, you may see the same recommendation.
Keep in mind rechargeable batteries will save you money in the long run over alkalines, AND they'll last for at least 100 pictures per charge (and probably many many more). You'll be very pleased with their performance, and may be angry with yourself for not buying them sooner. When at the store, look on the package for a power rating of at least 2500 mah.

Well i tried to take a picture and i took it and then it turned off once i took the picture

Sounds like the batteries.

Digital cameras are noteably, very demanding power suckers.
If they don't have brand new batteries, they shut off.

They requre top brand (Energizer or Duracell) batteries, and once they are used for even a short time; they will not be enough either.
(Dont' throw them out though, other less demanding things like Remote controlls will gladly use them for years)

The best bet is to use Rechargeable batteries, or have a $100/month budget for duracells.

Statistics you will need to look for in Rechargeable batteries are:

Type; Nickel Cadmium (Ni-Cd) or Nickel Metal Hydride (NiMH)

The Metal Hydride rechargeable battery is best since it charges faster and retains it charge longer, the old fashioned Nickel Cadmium battery used to be the best, but not any longer.

Rating: 900mAh; 1800mAh; 2200mAh; others not mentioned.

Unimportant note: The mAh means Milli Amphere Hours, which means how much power the battery cell will hold when fully charged. It is measured in Ampheres (Amps) per Hour, or in this case Milliamperes (1/1000 of an amp), but that's not important to know; all rechargeable batteries are rated by this number.

The number of mAh's you want are about 1000 or more,

Generally it's the more mAh's you have the more you can take pictures. Such as 900mAh will get about 50 to 250 pictures, but 1800mAh will get you twice as much.

Last note on Rechargable batteries: Only use a LiMH charger for LiMH batteries, and use a NiCd Charger for NiCd batteries.
If a charger dosn't say what type of batteiries it charges, it's the old fashioned NiCd (Nickel Cadmium) from the 1900's when that was the only type of rechageable battery.

Good luck with your Digital Camera.

Battery keeps dying

Most likely the charging circuitry has failed. When you fully charge the new battery what does the battery meter read on the camera? Your two options no matter what the case are repair vs. replacement. If you need further assistance let me know.

Camera drains battery while off

Assuming you're fully closing the front slider cover, the power switch is activated by the front slider cover so it may not be activating the switch or sensing that the cover fully closed. Sounds like it needs a professional service.
