How Long Does a Forklift Battery Last?
Batteries of electric forklifts are expensive units which require correct care and maintenance to be able to ensure a long life. These industrial grade batteries are very costly, large and heavy. The more efficient the battery, the more effective your equipment operators can be. Extending the battery life span is a main concern, not only because of the cost of replacement, but also because of the cost of down time connected with battery issues.
Charging Cycles
Keep in mind that you can just recharge forklift batteries when they are at least 80% discharged. The rate of discharge varies depending on various things like for example how many hours the forklift is being operated, the average load weight and the number of shifts being worked. For busy operations, charging nightly may be needed. However, don't forget that charging a battery very often will wear the battery more quickly.
Life Span
Commonly, a new forklift battery will last at least 1,500 charge cycles. Thus, if the forklift battery is being charged daily, the battery will last approximately five years. However, this is an average estimate. The life of the battery could be extended significantly beyond the average 1,500 charge cycles with correct maintenance.
Deep Discharge
A forklift battery should never be allowed to become totally discharged. Not only could damage to the battery result from what is called "deep discharge", the electrical components and motor of the forklift could sustain damage as well. This is because the damaged battery could change the amount of power being supplied to the forklift. The ability of the battery charger to communicate properly with the battery can also be compromised. In a worst-case scenario, the compromised charger could not completely charge the forklift battery, resulting in a destructive cycle of incomplete charges. A service technician might be required to return the charger to proper working order.
