When I'm not using my flashlight, where should I keep the batteries?
Keep the batteries in your flashlight when it's not in use—that way, you'll have a working flashlight when you need it. If you don't use your flashlight for a long period, turn the power switch on and off occasionally, just to make sure the flashlight is still working. It's also a good idea to change batteries periodically to prevent battery leakage if you don't use the flashlight for long periods.
You should also keep an unopened package of fresh Energizer® batteries where you store your flashlight. This way, you'll be sure to have a working flashlight and a backup set of batteries.
