GD, sir/madam,
What can cause using batteries with this charger with smaller capacity than minimum adviced by manual (minimum 150Ah, we use one set - 24v 560A 70Ah and second set with second charger - 24v 815A 50Ah)? Last time the working time of this kind of batteries is about 1year, after charge starts fall down, should I adjust any of float/equalize/boost charging time? Thank You
