Forklift Battery Troubleshooting (Part 5) – Electrolyte Problems

Forklift Battery Troubleshooting (Part 5) – Electrolyte Problems

Key issue: Low Electrolyte Level / High Water Consumption   Cause: Leaking cell jar Solution: Replace cell Cause: Overcharging Solution: Check charger Cause: Shorted cells Solution: Identify and replace Cause: Neglect of topping up Solution: Top up the battery Cause: High temperatures (charging / operating) Solution: Charge the battery in cooler location Cause: Battery at the end of its life Solution: Replace the battery   Key issue: Elevated Electrolyte Temperature  Cause: Overcharging  Solution: Check charger / charger settings Cause: Low water level Solution: Top up the battery Cause: Shorted cells Solution: Identify and replace See also: Forklift Battery Troubleshooting (Part 1) – Performance Problems Forklift Battery Troubleshooting (Part 2) – Overheating Problems Forklift Battery Troubleshooting (Part 3) – Irregular Voltage & Electrolyte Density Problems Forklift Battery Troubleshooting (Part 4) – Battery Overheating during... read more
Forklift Battery Troubleshooting (Part 4) – Battery Overheating during Charge

Forklift Battery Troubleshooting (Part 4) – Battery Overheating during Charge

Key issue: Battery overheats on charging Cause: Incorrect charger settings Solution: Check the charger parameters Cause: Poor ventilation Solution: Open battery cover and use fan while charging  Cause: Shorted cells Solution: Identify shorted cells, replace  Cause: Low electrolyte level (Possible loss of capacity)  Solution: Top up with water  Cause: Sulphated battery Solution: Perform desulfation routine on the battery.

Forklift Battery Troubleshooting (Part 3) – Irregular Voltage & Electrolyte Density Problems

Forklift Battery Troubleshooting (Part 3) – Irregular Voltage & Electrolyte Density Problems

Key Issue: Uneven voltages and electrolyte densities Cause: Regular overdischarging  Solution: Do not discharge the battery below 80% DOD Cause: Neglect of equalizing Solution: Give the battery an equalizing charge on a weekly basis Cause: Dirty battery top (External shorts) Solution: Clean, wipe dry after charging Cause: Internal shorts Solution: Check cells for short circuits if the battery runs down regularly or replace Cause: Loss of electrolyte Solution: Perform equalize charge or return to manufacturer for electrolyte gravity correction See also: Forklift Battery Troubleshooting (Part 1) – Performance Problems Forklift Battery Troubleshooting (Part 2) – Overheating Problems Forklift Battery Troubleshooting (Part 4) – Battery Overheating during Charge Forklift Battery Troubleshooting (Part 5) – Electrolyte... read more
Forklift Battery Troubleshooting (Part 2) – Overheating Problems

Forklift Battery Troubleshooting (Part 2) – Overheating Problems

Key Issue: Battery overheats on discharge Cause: Incorrect battery sizing (undersized) Solution: Install proper battery both in terms of the forklift and its duty cycle  Cause: Electrolyte level low Solution: Top up or increase top up frequency  Cause: Lift truck’s mechanical or electrical problems Solution: Check and repair vehicle Cause: High ambient temperature Solution: Recharge and store the battery in cooler environment  Cause: Shorted cell Solution: Check the battery for shorted cells. Replace if necessary Cause: Current leakage to ground Solution: Check the insulation of the battery as well as for electrolyte in the container See also: Forklift Battery Troubleshooting (Part 1) – Performance Problems Forklift Battery Troubleshooting (Part 3) – Irregular Voltage & Electrolyte Density Problems Forklift Battery Troubleshooting (Part 4) – Battery Overheating during Charge Forklift Battery Troubleshooting (Part 5) – Electrolyte... read more
