1.5AH Lithium Ion Battery

A 1.5 Ah battery can theoretically last 1.5 hours if the device draws 1 amp, but actual runtime depends on the device’s power consumption and battery type.

Understanding Battery Runtime

A 1.5 Ah (amp-hour) battery means it can supply 1.5 amps of current for one hour under ideal conditions, or proportionally less current for a longer time (1.5 Ah ÷ device current in amps = runtime in hours) . For example, if a device draws 0.5 amps, the battery would theoretically last 3 hours (1.5 ÷ 0.5 = 3 hours) .  However, real-world factors such as voltage drop, device cutoff voltage, and battery efficiency reduce this theoretical runtime
