Battery Storage
Standard Li-ion battery packs will gradually deteriorate, particularly if they are not stored in ideal
conditions.
When storing Li-Ion packs, you should consider these factors:
z
Fully charged packs deteriorate faster than partly discharged ones. For ideal storage, charge the
packs to 100% then discharge them to 50% charge before storing.
z
Do not allow stored battery packs to discharge completely, as this may permanently damage them.
Follow a regular maintenance charge policy for stored packs.
z
Avoid storing packs at temperatures greater than 30ºC (86ºF) as this speeds self-discharge and
battery ageing.
z
Storing packs at temperatures near 0ºC (32ºF) slows self-discharge and battery ageing, so packs
that are stored for a long period are best kept at these temperatures.
z
If you store battery packs at normal ambient temperatures, use this charging policy to maintain
battery pack condition:
{
Charge installed packs every 21 days to maintain their charge capacity.
{
Charge uninstalled packs every 6 months.
When you bring a handheld computer out of storage, you should charge it for at least 7 hours so that
both the main battery pack and the standby battery are fully charged.
