Engineering FAQ

What is the FM series mainly used for?

FM compact VRLA batteries are designed for standby power applications such as UPS, security systems, emergency lighting and small backup equipment.

Is FM a maintenance-free battery?

Yes. The sealed AGM VRLA design is maintenance-free under normal standby operating conditions.

Can one FM datasheet structure guide the whole FM series?

Yes. The FM series shares the same VRLA technology platform; individual pages keep their own voltage, capacity, dimensions and weight while using the same engineering behavior framework.
