10.3.6.2 Battery checking and care
Even so-called 'maintenance-free' batteries need a degree of care to obtain their maximum opera‐
tional life.
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.
Material Terminal grease
Distilled water
Cleaning rags
Protective gloves
Precondition The machine is shut down.
The machine is standing level.
The machine is fully vented, the pressure gauge reads 0 bar.
Machine cooled down.
1. Clean the casing and terminals.
2. Lightly grease the terminals to prevent corrosion.
3. Check that connections are tight and tighten if necessary.
Check the battery fluid 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.
If a battery casing leaks fluid, the battery must be replaced immediately.
1. WARNING!
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 fluid level
If the fluid level does not reach the mark -
➤ top up with distilled water.
Winter operation
Batteries are particularly stressed in winter. Only a fraction of the normal starting energy is availa‐
ble at low temperatures.
1. CAUTION!
Danger of batteries freezing.
Discharged batteries are subject to frost damage and can freeze at −10 °C.
➤ Check battery charge with a specific gravity tester.
➤ Recharge the battery
➤ Clean the battery terminals and wipe with grease.
2. Check the battery charge weekly.
Recharge as necessary.
