What are C10 solar batteries?

C rating is a rating of how quickly energy can be discharged from a battery. The rating is combined with a battery’s capacity to find determine the maximum discharge. The C rating is inversely proportional to the battery’s capacity, so as you move up in capacity, you can move down in C.

A 150 AH battery at C20, will last for 20 hours on a load of 7.5 A.

A 150 AH battery at C10 will last for 10 hours on a load of 15 A.

A 150 AH battery at C5 will last for 5 hours at a load of 30 A.

A C10 battery means it should not be discharged with in 10 hours otherwise the battery life decreases.
