Recommendations

Before buying a charger, next data must be determined:

a) CHARGE CYCLE

We advise you to consider your choice of the battery, and to examine all our chargers. Every model was designed for a specific application. Before you choose, check the next points:

1. Is the battery totally or partly discharged when it’s connected to the charger?
2. How much time is there to charge the battery?
3. Do you need a charger which can charge batteries with different tension and capacity? Contact us!

Wa charge curve

Consists in a principal charge phase and a final charge phase. The charger starts to charge with a maximal current (100 %), during the charge, the battery tension increases and the charge current decreases correspondingly. When 2.4V/cell is reached, the charge current is decreased to 50 % and the principal charge phase is ended. During the final charge phase, the charge current decreases to 25 %, and a battery tension of 2.65V/cell is reached ( = full battery tension).
