Your digital camera uses a rechargeable battery or a set of AA rechargeable batteries. Both of them will serve you pretty well if you follow a few simple tips. If your camera uses AA batteries, never use ordinary alkaline cells – even if they were included with your camera.
Save for the TV remote and buy a set of NiMH (nickel metal hydride) batteries and chargers that can be recharged right away. You can also get 18650 li ion rechargeable battery online.
This gives you a bit of money back and saves you a lot of money in the long run. With proper care, these battery bites will last in an individual cell four to five times per trip – and can be recharged up to 500 times.
If no battery is available, switch to Energizer E2 lithium battery. Although they are not renewable, they last a very, very long time. Smart passengers have several sets of lithium batteries in the trunk of their car so they have enough power when not plugged into a power outlet.
Your camera can use its own lithium-ion (li-ion) battery – lots of people do. The technology is good. These cells have no memory (that is, even if you stop the charge depletion cycle, they will still perform at their best).
The best advice for using your own lithium-ion battery: buy several (at least two). Have at least one for the camera and one for the charger. With three, you can store one on the camera, one in a spare bag, and one to charge for instant later use.
