As with other battery types, Lithium-Ion (LI) batteries will lose capacity over
time. Capacity deterioration is noticeable after one year of service whether the
battery is in use or not. It is difficult to precisely predict the finite life of a LI
battery, but cell manufacturers rate them at 500 charge cycles. In other words,
the batteries should be expected to take 500 full discharge/charge cycles
before needing replacement. This number is higher if partial discharging/
recharging is adhered to rather than full/deep discharging.
CAUTION
CAUTION
Only in case of long storage, to avoid deep discharge of the battery it is recommended to
partially recharge the battery every three months to keep the charge status at a
medium level.
As a reference, run a fast recharge for 20 minutes every three months on unused prod-
ucts to avoid any performance deterioration of the cell.
Storage of batteries for a long time at fully charged status or at fully discharged status
should be avoided.
The useful life of LI batteries depends on usage and number of charges, etc.,
after which they should be removed from service, especially in mission critical
applications. Do not continue to use a battery showing excessive loss of capac-
ity, it should be properly recycled / disposed of and replaced.
Collect and recycle waste batteries separately from the device to comply with
European Directive 2006/66/EC, 2011/65/EU, 2002/96/EC, 2012/19/EU and
subsequent modifications, US and China regulatory and other laws and regula-
tions about the environment.
CAUTION
Do not place the battery in microwave ovens, high-pressure containers or on induction
cookware.
Immediately discontinue use of the battery if, while using, charging or storing the bat-
tery, the battery emits an unusual smell, feels hot, changes color or shape, or appears
abnormal in any other way.
Do not replace the battery pack when the device is turned on.
Do not remove or damage the battery pack’s label.
Do not use the battery pack if it is damaged in any part.
Battery pack usage by children should be supervised.
