Refresh mode
General informa-
tion
Refresh mode is used to charge the battery if it is suspected that the battery has been in a
state of deep-discharge over a long period (e.g. battery sulphated)
- Battery is charged to maximum acid density
- Plates are reactivated (degradation of sulphate layer)
WARNING!
Risk of injury and damage from overheated batteries.
Only charge the battery under supervision! Monitor the battery temperature and interrupt
the charging process if necessary. Do not charge the battery to be reactivated in an ambi-
ent temperature exceeding 30°C. "Refresh" mode can cause the battery temperature to
rise to up to 45°C. Immediately disconnect the charger if the battery temperature exceeds
45°C.
CAUTION!
Refresh charging may damage the vehicle electronics.
Disconnect and remove the battery from the vehicle before carrying out a refresh charge.
The success of refresh charging depends on the degree of sulphation of the battery.
NOTE!
Use Refresh mode with caution, as refresh charging can cause fluid loss or drying-
out.
Also ensure that
► the battery is at room temperature (20 - 25°C)
► the battery capacity has been correctly set
► the battery has been disconnected from the vehicle electrical system
► refresh charging is carried out on batteries removed from the vehicle, either in the open
(without being exposed to direct sunlight) or in well-ventilated areas
CAUTION!
Risk of injury.
Wear eye protection and suitable protective clothing when handling battery acid. Rinse any
acid splashes thoroughly with clean water, and seek medical advice if necessary. On no
account inhale any of the gases and vapours released.
Refresh mode may be used on the following batteries:
- Wet batteries:
sealed batteries with a liquid electrolyte (identifiable on the vent plugs)
After reactivating, check the acid level and top up with distilled water if necessary.
- AGM batteries:
sealed batteries (VRLA) with immobilised electrolyte (sealant) and maintenance-free
wet batteries (MF)
- Gel batteries:
sealed batteries (VRLA) with immobilised electrolyte (gel)
