Over 100 Ah

"Over 100 Ah" probably refers to a particular class of battery that has a capacity greater than 100 amp-hours. AGM (Absorbent Glass Mat) batteries, which are a type of lead-acid battery, are often described in terms of their capacity in ampere-hours (Ah), a unit of electric charge that measures the amount of energy stored in a battery. As a result, "AGM/NBN over 100 Ah" most likely refers to AGM batteries with a capacity of over 100 Ah that were created especially for the National Broadband Network (NBN) system.
