YONHAN 12V/24V Battery Charger 0–15A Adjustable Current, SUPPLY Mode & Pulse Repair

The YONHAN Battery Charger is a versatile 12V/24V smart charger and maintainer with an adjustable 0–15A output, SUPPLY mode for dead batteries, and pulse repair to extend battery life.

This compact, workshop-ready unit is designed to handle everything from small motorcycle cells to large RV and truck batteries. It blends selectable current, multi-chemistry compatibility, and a multi-stage charging algorithm so you can safely charge, maintain, or revive most lead-acid and LiFePO4 batteries. Built-in protections and a stabilizing supply function make it useful for charging, diagnostics, and long-term storage.

How does the adjustable current help different vehicles?

You can fine-tune the charging rate to match the battery size and application, avoiding over-stressing smaller batteries while giving large batteries the boost they need. Lower currents are perfect for trickle charging and maintenance; higher currents speed up recovery for big starting batteries.

• 0.5A setting for motorcycles and small batteries
• 5–10A ideal for cars and light trucks
• Up to 15A for RVs, commercial trucks, and deep-cycle banks
• Selectable current prevents overheating and reduces charge time when appropriate

What battery types and vehicles will it work with?

This charger supports a broad range of battery chemistries and formats so you don’t need multiple chargers. It’s tuned for common automotive and leisure batteries plus newer long-life chemistries.

• Compatible with LiFePO4, AGM, GEL, EFB, Wet, MF, STD and deep-cycle batteries
• Suitable for cars, trucks, motorcycles, ATVs, UTVs, lawn mowers and marine batteries
• Works for both starting and deep-cycle applications
• Useful in garages, workshops, marinas and storage sheds

Can it recover a completely discharged battery?

Yes — the unit includes a SUPPLY mode that can revive batteries discharged to very low voltages and also act as a stable 12V power source. This is helpful for bringing back deeply drained batteries and for powering vehicle electronics during service or battery swaps.

• SUPPLY mode can attempt recovery from 0V scenarios
• Provides steady 12V output for diagnostics or accessory power
• Helps when replacing batteries without losing settings or power to systems
• Includes safety limits to stop unsafe recovery attempts

How does the charger protect and prolong battery life?

Smart charge stages combine with pulse repair to address common aging issues without user intervention. Protections guard against common faults while a trickle/maintenance phase keeps batteries healthy during long storage periods.

• Pulse repair helps reduce sulfation and restores some lost capacity
• Multi-stage charging prevents overcharge and balances cells where applicable
• Built-in reverse-polarity, short-circuit and temperature compensation protections
• Automatic maintenance/trickle mode for seasonal storage

Who is this for? The YONHAN 0–15A adjustable charger is aimed at homeowners, DIY mechanics, fleet operators, marina owners and anyone who maintains multiple vehicle types. If you need a single, safe device that charges, maintains, and can help recover deeply discharged batteries across a wide range of chemistries and sizes, this unit is a practical, all-in-one choice for garage or mobile use.
