condition. Check the following:
1. The cleanliness of the battery and the vehicle's battery
compartment.
2. Ensure systems are in place to prevent your battery being
connected to the improper charging equipment. Ensure
all connections are correct and that positive and negative
polarities, which are
respected. Improper connection may result in damage to
the battery, vehicle or charger.
3. Ensure that any charging equipment is suitable for use with
NexSys TPPL ATEX batteries.

4. Charge the battery before first use.

representative.
6. Operation
6.1 Operational safety
Batteries should be used in accordance with the EN 62485-3
standard ("Safety requirements for secondary batteries and
battery installations -
("Minimum requirements
safety protection of workers potentially at risk from explosive
atmospheres").
6.2 Operating conditions
The ATEX-approved operating temperature range is -20°C to
40°C.
The lifetime of the battery depends on a number of operating
conditions, in particular the operating temperature and depth
of discharge. Optimal battery life is obtained with the battery
at a temperature between +15°C and +35°C to maximise
performance and battery
the life of the battery, low temperatures reduce the available
capacity.
Operating at a depth of discharge of 60% or less will maximise
the battery lifetime. The maximum permissible discharge is
80% of C nominal capacity. From new, the battery reaches
5
its full capacity after approximately three charge/discharge
cycles.
6.3 Discharging
The valves on the top of the battery must not be sealed or
covered. Electrical connections
connected or disconnected
(without load). Discharges over 80% of the rated capacity are
categorised as deep discharges and are not acceptable as
they significantly reduce the life expectancy of the battery.
Discharged batteries MUST
MUST not be left in a discharged condition.
Note: The following statement
discharged batteries.
Discharged batteries can
a maximum of 80% depth of discharge (DOD). The cycle life of
the battery will depend on the DOD; the higher the DOD, the
shorter the cycle life. The presence of a discharge limiter on
the vehicle is necessary.
When discharged with currents in the range of I
following energy cut-off settings must be used:
• 60% DOD 1.96V
• 80% DOD 1.92V
At lower currents please seek advice from EnerSys.
