I think we all hate the surprise of a dead battery and none in supply! For example, think about those that run your: clock, fridge thermometer, weather stations, lanterns and flashlights, walkie-talkies, drills, extra installed smoke/CO2 alarms, small computer accessories, portable reading lights, etc.. Remember that batteries are perishable products that deteriorate from the start of their lives so check your battery health and supply as the camping season starts and remove and store the batteries when the camping season ends; and keep a check list of what appliances use which batteries and maintain a modest supply of extras.
- Batteries should be kept in a cool, dry place — ideally around 60 degrees Fahrenheit.
- Whenever possible, keep your batteries in their original packaging.
- Store batteries with their negative and positive terminals AWAY from each other, so that they're not conducting idly.
- Keep lithium and nickel-based batteries stored at a 40 percent charge.
- Store new and old batteries separately. If you store them together, power will be drawn from the new one, shortening its life.
- Leave any plastic caps on your batteries (like the 9V ones) until you need to use them.
- If you are not going to be using any battery-operated appliance for a month, remove the batteries and make sure to store them as stated above.
