What is 135 Ah?

135 Ah (amp-hours) is a unit of electric charge that indicates the capacity of a battery. It represents the amount of current a battery can deliver over a specific period; for example, a 135 Ah battery can theoretically supply 135 amps for one hour, or 67.5 amps for two hours. This measurement is crucial for determining how long a battery can power a device before needing to be recharged. Higher Ah ratings typically mean longer usage times before recharging is necessary.
