280 W Smart Charger for 6 V 12 V 24 V Batteries

The Wavlink GS280C delivers up to 280 W and 20 A across 6 V 12 V and 24 V systems. It charges lead-acid lithium and LiFePO4 cells found in cars motorcycles boats tractors and other vehicles. Four selectable modes cover charging maintenance desulfation and force recovery for deeply discharged packs.

LCD Display and Wide Temperature Range

An integrated LCD screen shows real-time voltage current mode and status during every charge cycle. The unit operates from minus 20 °C up to 40 °C so it remains functional in cold garages or hot engine bays. Built-in protections guard against reverse polarity overcharging short circuits and overheating without audible fan noise in normal use.

Pulse Repair and Multi-Stage Charging Under Load

Pulse repair technology detects sulphation and acid stratification then applies targeted pulses to restore capacity during extended sessions. Multi-stage logic moves from soft start through fast charge to trickle float automatically keeping output stable for hours. Force mode can revive batteries that regular chargers reject making the GS280C suitable for seasonal equipment that sits unused for months.

Questions about this item

How do I connect the Wavlink GS280C and what step do people often miss?

Clamp the red lead to positive and black to negative, then select the correct battery type and voltage (6 V, 12 V or 24 V) on the LCD before pressing start; forgetting to set the voltage is the common error.

What ongoing maintenance or replacement will the GS280C need?

No internal consumables require replacement; keep the cooling vents clear, wipe the LCD and clamps occasionally, and store the unit within the –20 °C to +40 °C operating range.

What limit appears first during a long charging session?

The charger delivers a maximum of 20 A and 280 W; if the battery draws near that limit for an extended period, thermal protection will reduce output until the unit cools.
