Maintenance of watertight batteries
- This type of battery needs no maintenance and does not produce any gas during normal use.
No ventilation is needed.
- The optimum temperature for use is between 10 degree C and 30 degrees C. Lower
temperatures will reduce the available capacity. Higher temperatures will increase the
batteries' self-discharge rate.
- Never open watertight batteries.
- Never add acid or distilled water.
- The pressure valves are used to seal the batteries and cannot be opened without being
destroyed.
- If the batteries overheat, a build-up of gas may develop: Keep away from the batteries.
