Never mix old batteries with new batteries; you will go through the new batteries quickly, and mixing can also cause bursting or leaking.

Never mix different kinds of batteries, such as rechargeables and disposables, or rechargeable batteries with different capacities.

If you are not going to use your camera for a while (two weeks or longer), take out the AA batteries; when you restart your camera, put them all back together into your camera as a group.

Have a way of marking or storing your batteries so that you know which batteries have been partially used and which have not.

If you buy a brand of battery that shows signs of leakage, never buy that brand again.

When storing batteries, check that the positive and negative ends do not touch.

When replacing batteries, make sure you put them in the battery compartment in the correct way according to the instructions; placing batteries incorrectly can damage some cameras.
