A smart lock spends most of its time in standby (very low current). When activated, it fires a high-current pulse to drive the motor mechanism and may simultaneously transmit wireless data. These pulses are short but demanding, and the battery must maintain sufficient voltage during the pulse to ensure reliable operation.
If the battery's internal resistance is too high, voltage drops during the pulse may cause the lock to fail or behave erratically. Standard batteries optimized for steady low-drain use may not maintain adequate voltage under pulse conditions. The right match is a battery with low internal resistance and strong pulse response.
