Whats the difference between 4 Ah and 5 Ah battery?

Capacity is the key difference between the 5Ah and 4Ah batteries. Technically the 5Ah battery draws more current for 1 hour or more time for the lower current. Other variations may be weight and height. The key factor in battery charging power is the volume/ weight of the chemical components that hold the charge.

Does a PLC need a battery?

In conclusion, the PLC battery is an essential component of the PLC system as it provides backup power to the processor’s non-volatile memory. This prevents loss of programmed software logic and PLC configuration in the occurrence of a power outage.
