Conserving Battery Power - Gateway SJM40 Reference Manual

Over the long term, use the battery at least once a
month, even if it was kept in a cool, dry place for
storage, but avoid frequent full discharges because
this puts additional strain on the battery. Several
partial discharges with frequent recharges are better
for a lithium-ion battery than one complete discharge,
and recharging a partially charged lithium-ion battery
does not cause harm because there is no memory.
