Capacity and Amp-Hours
When I was choosing a battery, I paid close attention to its capacity, measured in amp-hours (Ah). This number indicates how much energy the battery can store and how long it can power my devices. I found that selecting a battery with the right capacity for my needs was crucial. For example, if I needed to power a device that draws 1 amp, a 12Ah battery would last approximately 12 hours.
