The housing and the battery connections must not be cleaned with hard objects, e.g. a wire
brush!
The outside of the battery and the terminals should be cleaned regularly with a soft cloth.
This avoids current leaks and minimises the discharge rate.

1. Open the enclosure.
2. Clean the casing and terminals.
3. Lightly grease the terminals to prevent corrosion.
4. Check that the batteries and cable connections are properly seated and tighten if necessary.
Check the battery electrolyte level:
The fluid is generally sufficient for the life of the battery. Nevertheless, the fluid level should be
checked annually. The level should be up to the mark, 1 cm above the plates.
Replace the battery immediately if the casing leaks!
1.
NOTICE!
Battery destruction!
Topping up with pure acid will increase the electrolyte concentration and can destroy the bat‐
tery.
➤ Top up only with distilled water.
2. Check the electrolyte level.
If the electrolyte level does not reach the mark -
➤ top up with distilled water.
➤ Close the enclosure.
Winter operation:
Battery performance is particularly affected by winter operating conditions. Only a fraction of the
normal starting energy is available at low temperatures.
