4.13 Battery care
If the battery is still dry, it must be activated as described in section 4.13.2 Activating a dry-
charged battery.
The battery must be in operation within 2 months from being activated; if not, it needs to be
recharged first.
4.13.1 Electrolyte
Electrolyte in batteries is a sulphuric acid solution in distilled water.
The solution must be made up before being introduced into the battery.
4.13.2 Activating a dry-charged battery
• Take out the battery.
• Battery and electrolyte must be at equal temperature above 10 °C (50 °F).
• Remove cover and/or plug from each cell.
• Fill each cell with electrolyte until the level reaches the mark on the battery. If there is no mark
on the battery, the level must be above the plates for at least 10 mm (0.4 in) to 15 mm (0.6 in).
• Rock the battery a few times so that possible air bubbles can escape; wait 10 minutes and
check the level in each cell once more; if required, add electrolyte.
• Refit plugs and/or cover.
• Place the battery in the compressor.
Before handling batteries, read the relevant safety precautions and act
accordingly.
Read the safety instructions carefully.
Always pour the sulphuric acid carefully into the distilled water; never pour the
water into the acid.
