Battery

Episode 1022

John from Encinitas, CA

John wants to know how to properly take care of his batteries. There's a huge variety of advice about Lithium-ion batteries, but Leo says there's just a few things to keep in mind for extending the life of a battery. First, keep it charged. A Lithium-ion battery has about 500 recharge cycles in it. By keeping it charged and plugged in more often, it won't discharge and use up a cycle. He doesn't have to worry about overcharging either, because there's circuitry that prevents it from charging once it's fully charged. Secondly, if he's storing it long-term, he should keep it at 50% capacity.
