Lift Truck Maintenance 8-27
Section 8. Planned Maintenance
How to Get Maximum Battery Life
1. Follow normal battery maintenance procedures, re-charging
before 80% discharged and with periodic equalizing charges.
Let cool eight hours after charging before using.
2. Don’t add acid to a battery. Only a person trained and qualified
to do battery maintenance should determine if this is necessary.
3. Lift battery only with a correctly-constructed lifting device that will
not put pressure on the battery case.
4. Keep open flames, tools, and metal objects away from the top of
battery to prevent short circuits and explosions.
5. Do not overcharge.
6. Check the battery electrolyte level after each charging. Add
water if the top of the separator or plates are visible. Do not
overfill!
7. Keep the battery clean and dry. Wash down as needed.
8. Keep battery service records.
Battery Installation
1. Use only a lead-acid battery with the voltage and ampere-hour
rating specified for the truck.
2. When changing batteries on battery electric trucks, replacement
batteries must be of the service weight that falls within the
minimum/maximum range specified on truck nameplate.
3. Be sure truck is properly positioned and parking brake applied.
4. Handle battery only with approved lifting device.
5. Install the battery correctly in the truck and secure it in position.
Some trucks are equipped with battery stops or blocks.
Others do not require them. If the truck being serviced
has battery stops or blocks, be sure none are missing or
damaged. Replace them as necessary. If they are an
adjustable type, be sure they are correctly adjusted and
tightened. There should be no more than 1/2” total clear-
ance around the battery. The battery weight must be
within the range specified on the truck nameplate.
