Battery Tender 5 Bank 6V/12V 4A Selectable Battery Charger
Battery Tender 5 Bank 6V/12V 4A Selectable Battery Charger is a purpose-built battery charger/maintainer designed to safely charge and maintain 6V/12V flooded, AGM, GEL; 12V 4-cell LiFePO4. It uses an automatic charging profile and transitions to maintenance/float once the battery is full.
Best for
- Best when you want a 4A per battery maintainer: small to midsize starting batteries, seasonal storage
- Best for 5-battery setups: multiple vehicles, fleets, or shop benches
Key technical details
- SKU: 021-0133-DL-WH
- UPC: 734357113310
- System voltage: 6V/12V
- Output: 4A per battery
- Banks: 5
- Safety timer: 25-hour safety timer
Quick technical Q&A
- Will it overcharge my battery if I leave it connected?
- No—once the battery reaches full charge, it switches to a maintenance/float stage to hold storage voltage instead of continuously charging.
- What battery chemistry is it meant for?
- This unit is intended for 6V/12V flooded, AGM, GEL; 12V 4-cell LiFePO4. Always confirm your battery type and voltage before connecting.
- Do the banks charge independently?
- Yes—each output/bank is isolated so one weak battery won’t pull down the others; each battery gets its own charge profile.
