LEAD ACID CHARGING MODE
"Liquid" Battery Mode:
Liquid electrolyte batteries require higher loads to avoid any stratification of the electrolyte. Stratification
is a non-homogenous blend of the electrolyte. Acid is concentrated at the bottom and the water at the
top (due to its lower density). This phenomenon leads to freezing risks or oxidation of the plates. To
avoid this, Unimppt uses (in liquid batteries mode) an equalization charge that mixes the electrolyte,
which is essential to preserve the lifespan of your battery.
"AGM" Batteries Mode/ "GEL" Batteries Mode :
Hermetic batteries (AGM or GEL) require a precise control of the charge voltage to avoid gaz leaking.
Leaking is an electrochemical reaction that leads to the release of oxygen and hydrogen gases inside the
battery when the battery voltage reaches a point named "gasification voltage".
This voltage is different depending on the type of the batteries (AGM or GEL). Depending on the selected
mode, Unimppt releases a voltage level adapted to the technology of your battery to recharge up to
100%.
Regulation and controlled by external temperature
Chemical characteristics of the battery vary depending on the ambient temperature. With its external
temperature sensor, Unimppt adapts its charge voltage precisely in relation to the reference temperature
of 25°C, of +/- 20mV (+/-40mV - 24V by °C), which avoids overloads and under loads.
For flooded batteries, check the electrolyte level. If necessary, complete before charging.
For coupling, proceed as follows:
Some extra advice:
In case of parallel
connection,
favour
diagonal wiring for a
standardization of the
charge/discharge
Do
not
couple
batteries
with
different
capacities,
different
age
or
different technologies
Prefer a high-capacity
battery to 2 smalls
connected in parallel,
for equal capacity
