Intended use

4 Intended use
The Battery Refresher can charge or supply a retention voltage to 12 V batteries which are used to
generate power, reactivate or keep from premature ageing in vehicles or on boats.
The Battery Refresher can be used for the following types of battery:
• Lead automotive batteries
• Gel batteries
• Fleece batteries (AGM)
• Maintenance-free batteries
A
NOTICE!
The Battery Refresher may not be used on other battery types (such as NiCd, NiMH
etc.) or defective batteries (for example with a cell short circuit).

Technical description

The service life of most lead batteries is reduced by sulphation: lead sulphate forms into large,
smooth crystals over the course of time and the amorphous, spongy structure disappears. The abil-
ity to recharge and therefore the charging capacity gradually decreases and the battery ages.
The Battery Refresher extracts the battery energy and returns it as a current surge. This causes the
crystals to vibrate in their resonant frequency. They fall back into their amorphous structure. Their
molecules can be integrated back into the charging process which in turn increases the charging
voltage, starting current and the capacity of the battery again.
All lead batteries are protected from premature ageing.
Connecting the Battery Refresher makes sense for batteries up to 300° Ah.

NOTE
The Battery Refresher does not replace a charging device but only works in conjunction
with a charging device or while travelling.
