4 Intended use
The Battery Refresher can charge or supply a retention voltage to 12 V or 24 V batteries
(MBR-100-24) which are used to generate power, reactivate or keep from premature age-
ing 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
NOTICE!
A
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 dis-
appears. The ability 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 amor-
phous 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
I
The Battery Refresher does not replace a charging device but only works in con-
junction with a charging device or while travelling.
