12 V charger for 2–90 Ah lead-acid batteries

This automatic charger maintains SLA, AGM, GEL and VRLA cells from 2 to 90 Ah. It suits motorcycles, cars, RVs and snowmobiles. The unit handles both 6 V and 12 V systems with a maximum output of 3.8 A. It is designed for straightforward hook-up and unattended operation.

LCD display and detachable lead sets

A built-in LCD shows charging status while reverse-connection, over-charge, short-circuit, over-temperature and high-low voltage protections run automatically. Interchangeable alligator clips and ring terminals let you switch between quick top-ups and permanent mounting. The automatic cycle selects the correct profile once the terminal type and vehicle class are chosen.

Terminal choice simplifies daily use

Swappable leads mean you can clip on for occasional charging or bolt ring terminals for permanent connection to a seldom-used battery. The charger then manages the full cycle without further input. No software or app is involved; all control is via the front-panel buttons and display.
