1
Automatic recharge when battery voltage falls below 3.4 V. Charger off (0 mA) when battery voltage exceeds 3.6 V.
Note: Battery protected against operation at excessive temperatures (charging stopped when battery cell temperature < -5 °C or > 60 °C).
The emergency lighting LED driver will recharge the battery normally after running the test of 61347-2-7 CL 22.3 (abnormal operating conditions).
2
The battery will not be charged below 2.0 V.
3
The discharge current varies depending on the battery voltage and the LED voltage to maintain the constant output power.

over current.
7.4 Safety
7.4.1 Deep discharge protection
When the battery remains connected without charging for a long period of time
after the battery cut off of the driver the battery voltage can still drop. To make
sure the cells are not damaged by this voltage drop, the battery protection
prevents the battery from further discharge below 2.0 V.
7.4.2 Overcharge protection
In case of an error or the use of a wrong driver the battery gets overcharged.
The battery protection will disconnect the battery from the driver at a voltage of
3.9 V. A discharge of the battery is still possible after the protection circuit was
triggered to guarantee emergency operation.
