We know that AA batteries (or any others) lose charge because energy is taken out of them with use. The chemical reactions that generate the voltage occur, and this "uses up" the energy in the cell. This is the long and short of why batteries lose charge, and you can see it if you think it through. We can also see a situation where a cell loses charge when stored. No materials are perfect insulators. And lengthy storage, or storage under improper or poor circumstances will set up conditions under which leakage current could discharge a cell. Plain and simple.
If its a NiMH battery then yes. The Energizer charger will charge ANY brand of NiMH rechargeable batteries.
Which brand of AA batteries lasts the longest
For cameras there are mainly the AA batteries or the lithium ion battery pack that is rechargeable. The AA batteries are rechargeable as well, but the lithium ion are just more convenient.
Well the AAA will have more voltage, but the AA might have more AMPs per battery. you need to give more information about the batteries.
at the bottom of the computer there is a little cube then you put in two AA batteries in
No, only rechargeable batteries can be recharged.
It runs on 2 AA batteries.
Wii remotes run on 2 AA batteries but if you can get a pair of recharable batteries then yes you would need to charge them. (Pick your brand carefully, some batteries run out fast!)
The AX-Synth does not recharge the batteries. You have to get an external AA Ni-MH charger.
Yes that the Quick Charge II Instant Cell Phone Charger needs 2 AA batteries.
You'll have to get your batteries replaced. Some take AA batteries, but you may have to call the manufacturer if you have a propietary battery.
2 hours
You can't charge it...it works off 2 AA batteries
yes
If its a NiMH battery then yes. The Energizer charger will charge ANY brand of NiMH rechargeable batteries.
The different brand charger will charge the batteries. It's best to get the same brand as the batteries though. Having a different brand charger can ruin the batteries.
It sounds like your batteries won't hold their charge and need replacing, but before you do that, discharge them completely , for example by putting them in a torch with a bulb and then leaving it on until they are flat. (I am assuming you are using AA batteries). Then recharge them and see if it is any better. If not, get new ones - I would suggest you buy "Eneloop" brand AA batteries as they are very low-discharge : standard NMH rechargeables batteries lose their charge in a month when they are not even in the camera, unless you keep them in a cool place such as in the butter compartment in the refrigerator. Try it out.
