Giantz CT-3800 3.5A Auto Battery Charger 6V 12V AGM

A flat battery has a way of catching you off guard — whether it’s a car that won’t start, a pump that’s stopped working or a vehicle that’s been sitting idle too long. The Giantz CT-3800 is a fully automatic 3.5A battery charger designed to handle exactly these situations, with compatibility across 6V and 12V lead-acid batteries and 12V lithium-ion batteries, including WET, MF, EFB, GEL, LIB and AGM types.

Eight charging modes cover everything from standard 12V charging to Cold/AGM, small battery modes and a dedicated REPAIR mode that can recover old, sulphated or stratified lead-acid batteries that other chargers would write off. The built-in intelligent microprocessor manages the 8-step automatic charging cycle from start to finish, switching to float maintenance mode once fully charged so you won’t overcharge or damage your battery. Six-way protection covers sparks, reverse polarity, short circuits, overcurrent, overcharging and overheating — giving you genuine peace of mind when charging in the garage, shed or on the road.
