Illustrated explanation:
– Composition of a lead-acid battery:
sulfuric acid
electrolyte
– 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
automatic 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.
