BatteryUniversity.com is an on-line resource that provides practical battery knowledge for engineers, educators, students and battery users alike. The papers address battery chemistries, best battery choices and ways to make your battery last longer.
Nevermind the fact that the site is sponsered by battery analyzer and charger maker Cadex Electronics, it is a wonderful free resource for everyone who is concerned with the right treatment of their gadget batteries (a topic that can lead to endless discussions because even battery vendors don't seem to always agree on this).
