Calculating Your Ampere-Hour Requirements

To accurately calculate your Ampere-Hour requirements, list all the devices you intend to power with the Deep-Cycle Battery. Identify each device’s wattage (W) and the expected number of hours (h) it will use. Since the Ah rating is a measure of current over time, you’ll need to convert the total wattage into amperes (A) using the formula: watts (W) divided by voltage (V) equals amperes (A). After converting, multiply the amperage by the usage duration to find the energy consumption in Ah.

For instance, if a device runs on 120 watts in a system with a 12-volt battery, it would use 10 amperes (120W / 12V = 10A). If this device operates for 3 hours daily, it consumes 30 Ampere-hours daily (10A * 3h = 30Ah). Repeat this process for all devices and sum their total Ampere-Hour consumption to determine your overall Ah requirement. This calculation ensures you select a Deep-Cycle Battery with an Ah rating that matches or exceeds your total energy needs, considering any potential for expansion or increased demand in the future.
