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
Storage of batteries for long time at fully charged status or at fully dis-
charged status should be avoided.
CAUTION
Only in case of long storage, to avoid deep discharge of the battery it is rec-
ommended 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 products to avoid any performance deterioration of the cell.
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 capacity, it should be properly recycled 
/ disposed of and replaced. 
Collect and recycle waste batteries sepa
rately from the device to comply with European 
Directive 2006/66/EC, 2011/65/EU, 2002/96/EC and 2012/19/EU and subsequent modi-
fications, US and China regulatory and other l
aws and regulations about the environment.
