Key Issue: Forklift battery does not work full shift
- Cause: Incorrect battery sizing
- Solution: Install proper battery both in terms of the forklift and its duty cycle
- Cause: Battery not fully charged
- Solution: Check duty/recharging schedule/charger operation.
- Note: Do not use partially charged batteries for full shifts
- Cause: Cell(s) removed from the battery
- Solution: Replace as soon as possible
- Cause: Lift truck’s mechanical or electrical problems
- Solution: Check and repair vehicle
- Cause: Electrolyte contamination
- Solution: Check for the contamination source. Replace electrolyte or replace cells
- Cause: Short circuited cell(s)
- Solution: Identify by measuring voltage, specific gravity, temperature. Remove and replace cells
- Cause: Battery at the end of its life
- Solution: Perform a capacity test (C5). If the battery performs less than 80% of its nominal rating, replace
- Cause: Electrolyte loss or electrolyte low level
- Solution: Check the usage and the maintenance of the battery

why is my 48 volt forklift battery gassing off while it sits idle and disconected? It smells strongly of sulpher.

Dear Steven,
Here is a list of possible causes:
1. Shorted cells
2. Excessive dirt and electrolyte accumulation on the battery surface
3. Use of tap water
