Lithium batteries basics

Gigaom describes Why lithium-ion batteries die so young and provides a good rundown on how these batteries work. A lot of the ideas apply to most rechargeable batteries such as the lead acid batteries used in RV’s.

One common problem I see a lot is about the difference between energy and power.

When we talk about “dead” batteries, it’s important to understand two performance metrics: energy and power. For some applications, the rate at which you can get energy out of the battery is very important. That’s power. …

In cell phones, on the other hand, high power is less important than capacity, or how much energy the battery can hold. Higher-capacity batteries last longer on a single charge.

The advice to avoid deep cycling and excessive heat for best battery life apply to nearly any battery.
