I read a useful article on Gizmode on li-ion batteries. Thought I’d share it with you. Here are the tips (sounds simple, but I don’t comply with them!) See link for full article.

• Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
• Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss
• Keep your battery in cooler temperatures. Hot hot heat is not good for it
• If you're gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).
