4. Preventing premature failure of your Booster’s
batteries
Correctly recharging the Booster batteries, increases
its efficiency and its lifetime !
4.1. Recharging
The Booster must be imperatively put on permanent charge between use.
è
Why ?
n
Below 12,4V, the Booster batteries will start to sulphate and irreversible lose perform-
ance. The lower the voltage, and the longer the time spent in a discharged state, the
deeper the sulphation. When not in use, the Booster batteries must never drop below
12,4V (well-charged = 13V).
