Keep battery clean and dry.
• Remove battery cables (negative first).
• Clean battery posts (+ and −) and clamps
and grease with acid-free and acid-resistant
grease.
Ensure that clamps make good contact after
reassembling.
• Hand tighten the bolts only.
Every Vetus Maintenance-free battery has a
hydrometer (1) built into the cover.
Visual inspection of the hydrometer will show
one of three conditions:
• Green dot visible:
State of charge 65 % or more.
• Dark:
State of charge less than 65 %.
Recharge immediately.
• Clear or light yellow:
Electrolyte level low.
In case of low level, caused by overcharging
the battery for a long period of time with a
voltage too high, replace battery. Check alter-
nator and/or voltage regulator.
