So I was reading The Battery University on lithium batteries. I tend to use a lot of AA in AAA rechargeable batteries because I dislike buying new batteries to throw them away when they are used. Charging lithium I think is very similar to charging SLA batteries. Any opinions or suggestions?
One of the things I found most interesting, is it they strongly advise not charging the batteries to the Max apparently they do not have a memory like 9 Ni Cads do.

- Turn off the device or disconnect the load on charge to allow the current to drop unhindered during saturation. A parasitic load confuses the charger.
- Charge at a moderate temperature. Do not charge at freezing temperature. (See BU-410: Charging at High and Low Temperatures)
- Lithium-ion does not need to be fully charged; a partial charge is better.
- Not all chargers apply a full topping charge and the battery may not be fully charged when the “ready” signal appears; a 100 percent charge on a fuel gauge may be a lie.
- Discontinue using charger and/or battery if the battery gets excessively warm.
- Apply some charge to an empty battery before storing (40–50 percent SoC is ideal). (See BU-702: How to Store Batteries.)
