Introduction
As with other types of batteries, 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.
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 separately from the device in compliance with European
Directive 2006/66/EC, 2011/65/EU, 2002/96/EC and 2012/19/EU and subsequent modifica-
tions, US and China regulatory and others laws and regulations about the environment.

Replacing the
Battery Pack
1
Using a coin or a screwdriver, unscrew the bottom of the battery pack until it is disengaged.
The battery pack will rise slightly in the rear, pushed by the contact springs.
2
Extract the battery pack by slightly rotating the pack and pulling away from the reader.
CAUTION
Do not use the battery pack if it is damaged in any part.
Battery pack usage by children should be supervised.
CAUTION
Storage of batteries for long time at fully charged status or at fully discharged
status should be avoided.
CAUTION
In case of long storage, to avoid deep discharge of the battery it is recom-
mended 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.
Before proceeding, read “Battery Safety” on the preceding pages. Balluff recom-
mends annual replacement of rechargeable battery packs to ensure maximum
performance.
