This battery chemistry is Lithium Ion. As such it does not suffer from memory effect like older Nickel chemistry batteries, and requires no maintenance. It does however have a safety cut-off if left to discharge past a certain point, which will render the battery useless. If you are considering purchasing this battery as a spare, ensure you charge it fully upon receipt and charge again every 2-3 months if not in use. If using the battery constantly, please be aware that although this chemistry does not require maintenance for best performance, it does only have a life span of around 300 charge cycles. Therefore if you are charging it everyday it will likely only last a year.
