Charging
When charging the battery with an external charger, ob-
serve the following guidelines:
• For best results use chargers intended for charg-
ing LiFePO4 batteries. If you do not have such a
charger, you can use lead-acid battery chargers.
• The charger must not perform any desulfation ac-
tion.
• When using a configurable charger set the
constant current/constant voltage (CC/CV)
option with the following values:
Set the end of charge voltage to 14.4 V.
Set the recommended maximum charging
current for the battery.
• The maximum charging voltage should not ex-
ceed 14.5 V.
• At the end of the charging the charger can be dis-
connected, be turned off, or kept connected at
float voltage.
TLB150F: When the battery is being charged at tem-
peratures below 0 °C, the cell heating system is activat-
ed. The cell heating system uses the charger's energy
to power itself. Once the ideal charging temperature is
reached, the heating is switched off and the charging
begins. If during charging the temperature raises above
the permissible range, the internal battery management
system (BMS) will limit the charge to preserve battery
life.
Discharge
The internal battery management system (BMS) protects
the electronic system and the battery cells. It supports
a continuous current of 135 A. However, it is possible
to use higher currents for a limited time, in accordance
with the following values.
Discharging current
150 A
180 A
200 A
NOTICE! Damage hazard
• Do not discharge the battery outside
the temperature range of -20 °C ...
60 °C.
• If the voltage drops below 10.5 V
± 0.1 V, the battery generates an alarm
and deactivates the terminals.
8 Storing
The battery is active and connected to the electrical sys-
tem (e.g., of a vehicle):
Before storing fully charge the battery with a rec-
ommended battery charger for 1 to 2 days.
When the battery is not in use, ensure that the bat-
tery voltage does not drop below 12.6 V.
While storing the battery recharge it completely
every 30 days.
The battery is not connected to an electrical system
(shelf storing):
Before storing charge the battery fully or at least to
70 % using a recommended charger.
When the battery is active (green LED flashing),
recharge every 6 months.
If the battery is automatically switched off due to
a total discharge, it must be recharged as soon as
possible, but at least within 7 days.
