How Long Does a Forklift Battery Last?
Batteries of electric forklifts are expensive units that require correct maintenance and care to be able to guarantee a long life. These industrial grade batteries are large, heavy and costly. If the battery is more efficient, the more productive your equipment operators can be. Extending the life span of the battery is a top priority, not only because of the replacement cost, but also because of the expense of down time connected with battery problems.
Charging Cycles
Forklift batteries should be recharged only when they are at least 80% discharged. The discharge rate differs depending on different things like for example the number of hours the forklift is being used, the average weight of loads and the number of shifts being worked. For busy operations, nightly charging may be required. However, don't forget that charging a battery too frequently will wear the battery a lot faster.
Life Span
Brand new forklift batteries are usually made to last 1,500 charge cycles at least. Thus, if the forklift battery is being charged on a daily basis, the battery will last roughly five years. Nevertheless, this is an average estimation. The battery life span could be extended a lot beyond the average 1,500 charge cycles with correct maintenance.
Deep Discharge
A battery of the forklift must never be allowed to become totally discharged. Not only can damage to the battery be caused by what is known as a "deep discharge", the electrical parts and motor of the forklift can also sustain damage. This is because the damaged battery can change the amount of power being supplied to the forklift. The ability of the charger to communicate properly with the forklift battery can be compromised too. In a worst-case scenario, the compromised charger can not charge the forklift battery completely, causing a destructive cycle of incomplete charges. A service technician may be required to return the charger to good working condition.
