How does a lead-acid battery work ?
recharge
=
Return of the acid into the water
Elimination of the lead sulfate
charged battery
+/- 13V
Lead
sulfate
The acid is attracted by the
lead: forming of lead sulfate

Density of the electrolyte
charged battery : 1,28 kg/dm3
discharged battery : 1,15 kg/dm3
Frost temperature of the electrolyte
charged battery : -40°c
discharged battery : -6°c

Consequences of several successive discharge before recharge or deep discharge:
charged battery
+/- 13V
The acid is attracted by the
lead: forming of lead sulfate
start
=
discharge
1
2
Acid erodes the lead
Accumulation of sulfate
deeply discharged
b/- 11V
3
Return of the acid into the water
Traces of acid and sulfate on
the lead plates
recharged battery
irreversible damage
= loss of power
4
Never recharge the Booster on a non-automatic garage charger or on an automatic
charger set on « fast charge » or « boost » position.
n
You risk overcharging the Booster and higher than 14,7V, hydrogen may form inside of
the battery, resulting in explosion risk.
Never completely discharge the Booster’s battery.
n
The battery does not have a memory effect.
n
Danger of irreversible sulphatation.
Never recharge your Booster in 24V on board of a vehicle.
