Giantz 12V 20A Automatic Battery Charger

A flat battery doesn't announce itself — it just leaves you stranded. Whether it's your car refusing to start, your boat sitting dead at the ramp, or your caravan auxiliary battery needing a top-up, the Giantz 20A Battery Charger gives you a capable, fully automatic way to recover and maintain 12V lead acid batteries in the shed, garage or out in the field.

Built with integrated Pulse Width Modulation (PWM) technology, it delivers a continuous charge to your battery while an automatic floating charge mode kicks in once the battery is full — preventing overcharging damage without you needing to monitor it. Protection features cover over-voltage, over-temperature and short circuit scenarios, and it's SAA approved. The 90cm cable with quality battery clips keeps things practical, and at 1.2kg it's easy to stow in your vehicle or workshop without taking up much room. Suitable for both gel-cell and wet-cell lead acid batteries.
