The maximum time necessary for the battery to start accepting a measurable charge current, in relation to
voltage measured, is as follows.

Ensure the internal temperature of the battery never exceeds 45°C during recharging. If this occurs, stop
recharging for a few hours, then resume and complete the procedure.
At the end of the recharge cycle, battery voltage must be at least 14.4 – 15.0 V.
If this voltage is NOT reached (even if the battery was charged at constant current) indicates a general
deterioration in the state of the battery. In this case, replacing the battery is recommended even if the
vehicle will start.
Prolonged periods with the battery not in use (more than 2 weeks with the battery master switch ON) may
cause faults at the next recharge cycle. The voltage may reach the value of 14.4 – 15.0 V specified
previously, but the current in the battery may drop rapidly and the battery may fail to maintain charge for
the correct period.
Assessing charge level
Check the battery charge level (
