If the unit will not be used for more than two weeks, turn it off
(shutdown).
If you need to store the battery for an extended period of time,
place it in a cool dry place, and ensure that it is charged at
around 50 % of its capacity. Every three months during the
storage period, verify the battery level. Recharge the battery
when necessary, so that its charge level remains around 50 % of
the total capacity. This will ensure that you get the optimum
performance out of the battery.
