Sealed Lead AGM 12V

Sealed Lead AGM 12V

TECSUP proposes, via direct sale, a complete range of sealed lead AGM 12V batteries.

The AGM batteries have exceptional leek resistance, they are sealed and can be used in any position. Gas may escape from the security valves only in the event of overcharge or a default. The AGM batteries have an auto-discharge rate of less than 2% per month at -20°C and without maintenance, for life.

Main features

AGM batteries have an exceptional capacity of recuperation, even after a heavy or long discharge. Nevertheless, we have to point out that frequent heavy or prolonged discharges can entail premature wearing of the batteries (whatever the make of the battery).

AGM batteries used in cycles are recharged in 3 steps (IUU).
The first “BOOST” phase is characterized by a constant current I (max Intensity of the charger). The 2 following phases are characterized by a constant tension U. During the second phase “Absorbtion”, the voltage is maintained at a relatively high level in order to accelerate the recharge. During the third and final “Floating” phase, the tension is reduced to a level just sufficient to compensate the auto-discharge of the battery.
