When using an electric stacker, below what percentage of the battery capacity should you immediately stop working and charge the battery?

Stopping work and charging the battery when it reaches 20% capacity is crucial for the effective operation and longevity of an electric stacker's battery. A battery that is frequently discharged below this threshold can undergo deeper discharges, which can lead to significant degradation over time.

Charging the battery at or before it hits the 20% mark helps to ensure that it remains within optimal operating limits, which not only prolongs the battery's life but also maintains performance during use. Furthermore, running a battery down to very low levels can lead to interruptions in work, as well as potential safety hazards if the equipment stops unexpectedly because of a depleted battery.

This practice is part of standard operating procedures for electric stackers to maintain efficiency and reliability in material handling tasks.
