What is the charge rate for a 100Ah AGM battery?

The charge rate for a 100Ah AGM (Absorbent Glass Mat) battery is commonly expressed as a fraction of its capacity, known as the “C-rate.” The C-rate represents the current at which a battery is charged or discharged relative to its capacity.

For example:

• A charge rate of C/5 means the current is one-fifth (1/5) of the battery’s capacity.
• For a 100Ah AGM battery, a C/5 charge rate would be 20 amps (100Ah / 5).

It’s important to note that the charge rate can vary based on the specific recommendations of the battery manufacturer. AGM batteries typically have a recommended charge rate, and exceeding this rate could lead to issues such as overheating and reduced battery life.

Always refer to the manufacturer’s guidelines and specifications for the particular AGM battery you are using to determine the appropriate charge rate for optimal performance and longevity.
