The booster WA121525 is used for optimal charging of 6-cell 12V lead-acid, lead-gel AGM and lithium batteries in motorhomes while driving independently of the alternator voltage. Installation is theoretically possible in all motorhomes. In cases where the charging and refrigerator lines are not wired separately from the starter battery, additional components are required for installation. Please contact your specialist dealer for this. For vehicles with alternators with energy-saving charging strategies (Euro 6), the use of a booster is absolutely necessary, as the charging voltage of the alternator can fluctuate greatly (12.6 - 15.0 V). With conventional alternators, the residential battery charge is also improved by using the booster WA121525. For AGM batteries that require a charging voltage of 14.7V or more, the use of a booster is essential. The booster WA121525 is a clocked up/down converter that compensates for fluctuating alternator voltage and provides high charging current.
