Generator Batteries Overheating
Most generator batteries are VLRA batteries & designed to operate at higher temperatures than standard batteries. However this doesn’t mean Generator batteries overheating can’t happen.
VRLA stands for Voltage Regulated Lead Acid.
Generally, situated close to a generator, therefore designed to operate at between 20-40C.
Should the operating temperature for long periods remain for instance over 35°C, then this High battery temperature will significantly reduce the life of the battery.
Generator Batteries overheating will cause the battery to swell, which if extreme, could cause the outer casing of the batteries to crack and leak acid.
When the ambient temperature remains high, then fluid in the batteries will dry out faster too.
Check weekly all generator batteries for:
- Fluid – Top up if necessary- Never let a battery dry out
- Corrosion on the terminals- clean and grease if required
- Ensure the tops on the batteries are tightly closed
- Never leave a top off any battery compartment
- Battery links are tight- no loose
- Always fit a battery that is bigger than required
- Rather than substituting with a NON compliant smaller battery.
- Any leaks- Clean with a clean cloth to spot any leaks
- Any damage- Accidental by personnel
- Only use global brand batteries
- Never use cheap batteries
Make a written note of the condition of the batteries each week for reference.
Never expect a Generator battery to last forever – Replace at least every 4 years or sooner if operating in a hot environment to prevent Generator batteries overheating.
Power Continuity can replace all Generator batteries
