Unlike disposable batteries — which need to be replaced when they die — rechargeable batteries can reverse the flow of energy. So as the name suggests, you can charge them back up. But Li-ion batteries aren’t just rechargeable, they’re lighter and more powerful than other rechargeable batteries (like alkaline), too. So ideally, you’d be able to recharge these babies forever.
But IRL, as we all know, ya can’t. Li-ions batteries actually have a lifespans of around 300-500 discharge/charge cycles. There are a number of things that cause them to erode over time and a ton of contradicting myths out there on how to slow that erosion down. So how can you actually maximize your battery lifespan?
