Quick technical Q&A

Will it overcharge my battery if I leave it connected?
No—once the battery reaches full charge, it switches to a maintenance/float stage to hold storage voltage instead of continuously charging.
What battery chemistry is it meant for?
This unit is intended for AGM, GEL, and standard flooded/sealed lead-acid. Always confirm your battery type and voltage before connecting.
How do I choose the right amperage?
Lower amps are ideal for maintenance and small batteries; higher amps are better for faster recovery on larger batteries. If unsure, pick the lowest output that comfortably meets your use case.
