How does a lead-acid battery work ?
1
charged battery
+/- 13V
Frost temperature of the electrolyte
charged battery : -40°c
discharged battery : -6°c
Density of the electrolyte
charged battery : 1,28 kg/dm3
discharged battery : 1,15 kg/dm3
Consequences of several successive discharge before recharge or deep discharge:
1
charged battery
+/- 13V
2.
Never recharge the Booster on a non-automatic garage charger or on an auto-
matic charger set on « fast charge » or « boost » position.
You risk overcharging the Booster and higher than 14,7V, hydrogen may form
inside of the batteries, resulting in explosion risk.
3.
Never recharge the Booster 12/24V via the cigarette lighter plug of the Booster.
The cigarette lighter plug (outlet 12V) is only connected to one battery and is
just provided for the connection of a portable lamp 12V (maximum 16A) or all
others accessory 12V.
2
Lead
sulfate
start
=
discharge
The acid is attracted by the
lead: forming of lead sulfate
2
start
=
discharge
The acid is attracted by the
lead: forming of lead sulfate
3
recharge
=
Return of the acid into the water
Elimination of the lead sulfate
3
deeply discharged
battery +/- 11V
Acid erodes the lead
Accumulation of sulfate
EN
4
recharged battery
Return of the acid into the water
Traces of acid and sulfate on
the lead plates
irreversible damage
= loss of power
