    I have the same problem. The camera tells me that the batteries are empty even if they are new. If i use rechargeable batteries the work for a short moment.

The camera has a design flaw.
Maybe HP can fix it with a firmware update but it's not likely.

I used an precision DC power supply to perform some electronics tests to find out what is going on with this model.

The issue is that AA NiMH batteries are rated at 1.2V DC each, and 2 AA"s in series add up to 2.4V.
Meanwhile the camera wants 2.7 volts DC or higher otherwise it gets the low battery error.

That is the flaw and we can't change that. It should continue to run at much lower voltage levels like other camera's and be able to use the full charge of the battery but it won't. So it runs the battery down from 100% down to about 98% and then it complains and stops.

Note that NiMH' batteries when fully charged are a bit above their rated value.. They actually have about 1.35V each so 2.7V total in this case. That's enough to start the camera but it doesn't last because in record mode the camera draws 450mA of current from the batteries (which is unusually high) and it quickly pulls the battery below the 2.7V level and the error comes up even though the batteries are still almost fully charged.

I measured 960mA of current draw when it's charging the flash which is a huge amount.
So this is just a really inefficient camera compounded by a low battery cutout circuit design flaw that is too sensitive.

We can't fix the design flaw but you could use higher voltage batteries. Granted,, this is not a great solution since you can't use NiMH rechargeables then but at least it gives you some options

Alkaline are rated at 1.5V each and even though they don't normally last very well compared to NiMH (due to higher internal resistance) they would last a while in this case. Perhaps 50-100 photo's or less if using the flash.

A better but more expensive solution is to use Lithium AA's. They have at least 1.6 Volts each and are very strong.
They are not rechargeable but you should get a lot of shots with a set of those, then look for a better camera.

Unfortunately this camera is far below average is pretty much every other category as well, such as high noise levels, low image sharpness, lack of any manual controls or dedicated control buttons for macro, focus, ISO, alternate screen modes to display useful info such as shutter speed or any other features that most camera's have by default. It has a 4 way rocker switch on the back but they didn't connect any functions to it.

It's also one of the slowest camera's made. Any Nikon or Canon would be a huge upgrade in features, quality, battery life, and photo quality. I have quite a few camera's and 20 years experience and can tell good features and those that are marginal. So lets just say that even though I only paid $39 (New) for this HP as a cheap spare it's going back to the store because it's just too lousy at everything. I can handle the 5Meg resolution which isn't a lot. I even have a 2Meg Nikon and a 4Meg Canon G3 from years ago that still take excellent, clear photo's. But this 5Meg HP can't even keep up with a 5 year old, 2 Meg camera.

I have a Fujifilm Fine pix S2900 which will not switch on correctly. It comes on and 5 seconds later switches off. I have replaced the batteries.

Often the battery contacts can get dirty. My Kodak does the same thing. When the camera tests the battery for power, the poor contacts make the camera think the battery is nearly empty so it shuts down. Give the contacts a good clean with alcohol and check they are correctly aligned. Clean the batteries too.

Which AA battery shall I buy for my digital camera? 1500? 1000? 2500?

Although you could use these, do not use alkaline batteries unless it is absolutely necessary. In some cases, alkaline batteries may have a shorter service life than NiMH. Alkaline battery performance is limited, especially at low temperatures. The use of NiMH batteries is recommended.
Never use manganese (Zinc-Carbon) batteries in electronic devices.
These batteries are only to be used in flash lights. The lower capacities suggest NiCd batterie. Also don't use these.
A set of new NiMH batteries, from 2000 to 2600 mAh with a good charger, will be fine.
Two things.
There are very fast chargers around. Don't invest in them. I payed 80 euro for a quick charger. Could charge 2700 mAh batteries in 15 minutes. The charger killed all my NiMH batteries I had (more than 40) It took me till the fifth or so died, before I realised it could be the charger. Since I stopped all my batteries one by one died and I had to replace them all
I now have some "fast" chargers that take 2 to 3 hours and the new batteries Can handle that.
Better buy a slower charger and some good batteries, than the other way around.
Second. Test the 2600 mAh batteries, if they fit.
To put more capacity in the "same" AA battery some brands made them slightly thicker. So it could be you can't get the largest ones in your camera.

I put new batteries into the camera but it continually tells me "low battery". What's wrong??? Do I need a specific brand or type of battery?

Yes, you are correct.

Digital camera need a high drain battery like NIMH or ALKALINE type, and don't a multi purpose ( standard battery).

My favorite battery is Energizer 2500 mAH ( recharged type).

Please check the battery you are using right now and replace it as guided above. If there is no internal problem on your digital camera, this recommend batteries will working just fine.

I have a Canon Powershot A590. The battery life is HORRIBLE! Is this a Camera problem? They do not last long at All.

Try getting some quality rechargable NiMH batteries and see if they last longer for you. The ones that I use in my A590 are rated at 2500 mah and last quite a while so far. I wouldn't recommend batteries rated at less than 2000 mah for this camera.

Best regards,

Low battery warning

What type of batteries did you buy?

For digital cameras, you want to use batteries with high milliamp hour (mah) rating: "2500 mah" if they are rechargeable.

If you bought regular batteries, you want to use good quality. Look for the "e2" or "better for digital equipment" type.

Does the camera have a DC power plug option? Try taking pictures with it plugged in if it does. If it still malfunctions with power right from the wall, then you bought a bad camera.

Extremely short battery life

do you use alkeline batteries? if yes then they would end in 20-25 shots. Instead, use rechargable batteries of 2500 mah which will last long, very long. On my Cybershot H1, they give aproximate 350 shots with single recharge.

Go for Sony Original Batteries or Uniross brand also works fine.

2300 mah/ 2500 Mah any will work.. :-)

Sony DSC-P93 battery replacement question

NiMH batteries. You can use the larger mAh AA. It has more capacity and should give you longer service before needing recharge. The battery manufacturers recommend that you do not mix the batteries. i.e. don't use mAh 2100 and mAh 2500 as one set, use all 2100 or all 2500 as one set.
