Battery Tender WaveCharge 4-Bank 12V/6V 12 Amp On-Board Marine Battery Charger
The Battery Tender WaveCharge 022-1004-DL-WH is a
4-bank on-board charger that simultaneously charges up to four 12V or 6V batteries at 3 amps per bank
, carrying
IP67 and Marine UL ratings for weather, shock, and vibration resistance.
Marine technicians and boat owners install the unit permanently in bilge compartments, engine rooms, and helm consoles for continuous unattended battery maintenance.
Compatibility & Applications
- Fits any installation requiring simultaneous charge of up to four 6V or 12V batteries from a single unit.
- Mounts permanently in engine rooms rated for fuel-vapor environments; UL marine ignition certification required for those locations.
-
Pairs with all 12V lead-acid, flooded, AGM, and gel cell batteries and lithium battery banks
— starting, house, and trolling motor banks simultaneously. -
Charges each bank independently, regardless of battery chemistry
, allowing mixed-chemistry configurations across the four outputs. -
Wires to batteries via marine-grade fused battery quick disconnects
included with each bank’s harness combo cable. - Drops into multi-battery center-console sportfish, walkaround, and dual-console boats 18–40 ft running separate starting, house, and trolling motor banks; replaces single-bank charger arrays requiring multiple AC outlets.
The unit employs a fully automatic 4-step charging process, switching from full charge mode to float charge mode, with spark-proof technology, reverse charging warnings, and ignition protection for safe long-term connection to both AC power and batteries.
Unlike single-output marine chargers, the WaveCharge delivers a full, independent 3 A circuit to each bank simultaneously — no output sharing across connected batteries.
