Tired of throwing away old batteries? Consider switching to rechargeable batteries, which provide the same power with less waste. They’re easy to recharge at home, and most are designed to last for hundreds (to thousands) of charge cycles, and maintain their charge for years. While disposable batteries start at 1.5 volts of energy and lower until they’re dead, rechargeable batteries use 1.2 volts of energy throughout their lifespan, giving you optimal battery performance. And while a charge and battery set might cost more at first, not having to constantly replace the batteries for your toys and devices means it’s a worthwhile investment.
