Smart 25A 12V Battery Charger with Four Current Settings 8-Stage Maintenance and 100A Engine Start – TowerTop

A smart 12V battery charger provides adjustable 2A, 10A, 25A and automatic charging for compatible sealed lead-acid batteries. TowerTop’s selected 25A model supports standard, AGM, gel, wet, MF, EFB, calcium and deep-cycle batteries used in cars, boats, RVs and powersports equipment.

The eight-stage program moves through desulfation, soft start, bulk, absorption, analysis, repair, float and pulse maintenance. An LCD shows charge stage and operating data, while memory restores the most recent settings after power loss. A separate 100A engine-start mode provides a 100-second starting assist, and winter mode adjusts voltage for cold conditions. Spark, polarity, voltage, current, temperature and short-circuit safeguards support proper use. This description covers the selected 25A configuration; the 25A Max Pro is a separate variant.
