How does a lead-acid battery work ?

lead
sulfate
start
=
discharge
charged battery
+/- 13V
recharge
=
the acid is attracted by the
lead: forming of lead sulfate
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
In a vehicle
Immediate recharge
through the alternator
=
maximal life span
- return of the acid into
the water
- elimination of the lead sulfate
With a Jump starter
PROPULSTATION®

the acid is attracted by the
lead: forming of lead sulfate
- acid erodes the lead
- accumulation of sulfate
provoked by a consumer, an alternator breakdown or bad connections, oxidation,
* Discharges
stocking, wintering, self-discharge… The deeper the discharge and the longer the time before
recharge, the more important the irreversible sulfate layer, preventing the current from entering or
going out the lead. Premature death of the battery. The irreversible sulfating begins under 12,4V.

recharged battery
- return of the acid into
the water
- traces of acid and sulfate
on the lead plates
Irreversible damage
= loss of power
