  • Maintenance and recondition modes extend battery life

Two-Pack Smart Charger for Lead-Acid and LiFePO4

This pack contains two 4-amp automatic chargers that handle 6 V and 12 V systems. They charge AGM, gel, VRLA, SLA, wet cell, and LiFePO4 batteries found in cars, motorcycles, ATVs, RVs, boats, and lawn equipment. Microprocessor control prevents overcharging during long-term connection.

Sealed IP65 Case for Continuous Outdoor Use

The fully sealed housing resists dust, oil, and moisture so the units survive permanent mounting in engine bays or on trailer frames. Maintenance, recondition, supply, and winter modes keep batteries healthy through seasonal storage without overheating the electronics. Alligator clips and ring terminals stay attached for quick reconnection.

4-Amp Output Sets the Charge Speed

A 4 A maximum current means mid-size automotive batteries reach full charge in hours rather than overnight, while smaller powersport batteries finish faster. Buyers with large deep-cycle banks or multiple vehicles on one maintainer will find the rate too slow for practical recovery.

Questions about this item

Does the charger run hot or make noise when left on overnight?

The sealed IP65 case is dust-resistant, oil-resistant and anti-moisture with no moving parts, so it stays quiet and cool during continuous float charging.

What battery terminals or cables do I need to connect it?

Both alligator clips and ring terminals are included in the box, so no extra cables are required for standard lead-acid or LiFePO4 batteries.

Will the 6 V and 12 V modes work with the older flooded battery in my classic motorcycle?

Yes, the charger supports 6 V and 12 V wet/flooded lead-acid batteries along with AGM and LiFePO4 types, covering older and newer chemistries alike.
