What to Compare Before Buying
- System voltage: Check whether your battery is 12V or 24V, because this charger supports both.
- Battery type: Match the battery chemistry with the supported battery types if you plan to use it on a specific battery.
- Charging current: Compare the stated 20A and 8A output with the charging setup you need.
- Display and monitoring: If you want live charging information, this model includes an LCD screen with multiple readouts.
- Placement: The 2 m power cord affects how close the charger needs to be to the mains socket.
Compatibility, Size and Fit
This charger is intended for 12V and 24V battery systems and is described as working with lead-acid and LiFePO4 batteries, including AGM, GEL, EFB, SLA, flooded (WET), calcium and deep-cycle batteries. Check the battery system voltage and chemistry before choosing an offer.
The charger is also described as suitable for vehicles such as cars, motorbikes, motorcycles, vans, trucks, lawn mowers and boats. Confirm that the battery and charging setup match the stated support before use.
What Else You May Need
A suitable mains supply is needed because the charger uses 100-240V~ 50/60Hz input. If you plan to use the unit in a fixed location, allow for the 2 m power cord when planning where it will sit.
How It Works
The charger uses an automatic 7-stage charging process. It detects battery condition, charges the battery and then switches to float or trickle maintenance mode once charging is complete. It also includes a pulse repair mode and winter and summer temperature compensation.
Safe Use and Important Precautions
The charger includes reverse polarity, over-current, over-heat, short-circuit and over-voltage protection, plus a built-in cooling fan and fireproof materials. Pulse repair is not described as a way to revive completely dead batteries, repair physically damaged batteries or jump-start vehicles. Follow the manufacturer’s instructions for the exact battery and charging setup.
Before You Decide
Confirm the battery voltage and chemistry match the charger support, and check whether the 2 m power cord suits your charging location. If you want live charging information, the LCD display is a useful part of this model.
