With nonrechargeable batteries, take a few simple precautions:
- Don't recharge them, expose them to high heat, subject them to strong impact, or get them wet. They could explode.
- Don't mix types, brands, or ages.
- Don't install batteries backward.
- Remove batteries if the device is powered by household current.
- Dispose of a battery that feels hot, changes color or shape, or emits an odor.
- It's OK to throw used alkalines in the trash if your community won't recycle them. But don't put them in metal-filled containers
because they could overheat.
