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).

The battery will not be charged below 2.0 V.
7.5 Safety
7.5.1 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.
7.5.2 Overcharge protection
If 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.
7.5.3 Short-circuit protection
In case of a short circuit the battery protection opens the connection to the
driver and the output is therefore free of voltage. The output will be reactivated
again when the short circuit is removed.
7.5.4 Overtemperature protection
The battery is protected against temporary thermal overheating. If the tempera-
ture limit is exceeded the further charging of the battery is no longer possible.
The temperature protection is activated below approx. 0 °C and above approx.
+60 °C. The discharging of the battery is still possible to guarantee emergency
operation.
