Refresh mode

General informa- Refresh mode is used to charge the battery if it is suspected that the battery has been in a
tion state of deep-discharge over a long period (e.g. battery sulphated)
-
-
The success of refresh charging depends on the degree of sulphation of the battery.
Refresh mode may be used on the following batteries:

Reactivating bat-
teries

64
Battery is charged to maximum acid density
Plates are reactivated (degradation of sulphate layer)
WARNING! Risk of injury and damage from overheated batteries. Do not charge
the battery to be reactivated in an ambient temperature exceeding 30°C. Refresh
mode can cause the battery temperature to rise to up to 45°C. Immediately dis-
connect 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.
NOTE! Use Refresh mode with caution as it 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 ar-
eas
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.
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)
CAUTION! Deeply discharged batteries are liable to freeze at temperatures of
0°C and below. Risk of damage when battery is frozen. Before starting refresh
charging, ensure that the acid in the battery to be refreshed is not frozen.
