Used forklift batteries are extremely heavy duty and can be recharged a number of times. By following these basic tips, you will extend the useful life of your forklift battery significantly, saving you money and reducing forklift downtime. Replacing the water in the battery will help keep the interior from corroding, and distilled or deionized water is preferred. The fluid level should typically be about ¼’’ below the vent wall neck after the battery is charged, and fluid should not be added before charging the used battery.
When using a forklift battery, do not discharge more than 80%. An average life cycle that helps ensure a longer lasting forklift battery is around a 50% discharge. The reconditioned, used battery should also be equalized every 5 to ten charge cycles, and this is basically a controlled overcharging that adjusts the voltage difference between the cells. It also helps get rid of the sulfate particles that build up on the plates.
If your used forklift’s battery ever overspills, make sure to wash it immediately with water and baking soda to stop corrosion from forming on top of or underneath the battery. If this isn’t done quickly the battery can be completely ruined. It is a good idea to wash the outside of the battery twice a year because acid vapors escape during recharge. These vapors cause residue to build up around the vent cap area, which will eventually corrode and damage the outside of the battery.
