Rechargeable batteries
Always hold the battery 14.4 V (10) upright when inserting it in the drive unitor the rapid charger.
If inserted at an angle it can cause damage to the contacts and result in a short circuit which
damages the battery.
Total discharging by undervoltage
The Li-Ion batteries may not drop below a minimum voltage because otherwise the battery could
be damaged by "total discharge". The cells of the REMS Li-Ion battery are delivered pre-charged
to approx. 40 %. Therefore the Li-Ion batteries must be charged before use and recharged
regularly. Failure to observe this regulation of the cell manufacturer can lead to damage to the
Li-Ion battery by total discharging.
Total discharging due to storage
If a relatively low charged Li-Ion battery is stored, self discharging can lead to total discharge
damage of the battery after longer storage. Li-Ion batteries must therefore be charged before
storing and recharged every six months at the latest and charged again before use.
Charge the battery before use. Recharge Li-Ion batteries regularly to avoid their total
discharge. The rechargeable battery will be damaged by total discharge.

Only use a REMS rapid charger for charging. New Li-Ion batteries and Li-Ion batteries which have
not been used for a long time only reach full capacity after several charges. Non-rechargeable
batteries may not be charged.
Battery charging status check for all Li-Ion cordless presses
All REMS cordless presses made as of 2011-01-01 are equipped with an electronic battery
charging status check with battery charge indication by a 2-coloured green/red LED (8). The LED
lights green when the battery is fully or still sufficiently charged. The LED lights red when the
battery must be charged. If this condition occurs during pressing and the pressing process is not
finished, the pressing must be completed with a fully charged Li-Ion battery. If the drive unit is not
used, the LED goes out after approx. 2 hours but comes on again when the drive unit is switched
back on.
