Repco 12V 800A Sealed AGM Battery Jump Starter - RCJS800

Repco RCJS800 12V 800A Sealed AGM Battery Jump Starter: Reliable and Compact Power

If you’re looking for a jump starter that’s easy to use, compact enough to fit in your vehicle boot, and trustworthy enough to handle most smaller petrol vehicles, the Repco RCJS800 is a solid option. With its sealed AGM battery and smart safety features, it’s designed to give you peace of mind when you need it most.

Compact Design Made for Convenience

Unlike bulkier jump starters, the RCJS800 is built to fit neatly into the luggage compartment of nearly any car. Its compact size doesn’t mean a compromise on power — it delivers up to 800 amps, making it suitable for petrol engines up to 2.0 litres, motorcycles, and ATVs. With its included battery leads and a handy protective carry bag, it’s simple to carry and store, so you’re always prepared.

Safe and User Friendly

This jump starter incorporates a range of safety features that protect both you and your vehicle. The MOSFET system protects against short circuits, surges, sparks, reverse polarity connections, and even detects if you accidentally connect to a 24-volt battery system, which could damage the device and vehicle. There’s also a smart low-voltage alarm that lets you know when the internal battery dips below 60%, so you can recharge it before it’s too late.

Power for Everyday Vehicles

While the RCJS800 is aimed at smaller engines with up to 2.0-litre petrol capacity, it covers a surprising number of vehicles including motorcycles and ATVs. Repco also offers larger versions in the range: the RCJS1200 for petrol engines up to 3.5 litres, and the RCJS1700 which handles petrol engines to 5.0 litres and diesel engines up to 3.5 litres — so there’s an option for most needs.

Additional Features That Make a Difference

Beyond jump-starting, the RCJS800 includes two 2.4 amp USB ports, handy for charging mobile phones, tablets, or other portable devices when you’re off the grid. An LED emergency light provides illumination in dark conditions, while a charging indicator keeps you informed about battery status. The inbuilt three-stage smart charger ensures safe, efficient recharging from a standard 240V supply, making it easy to keep ready and reliable.

Practical Tips and Usage

When using the jump starter, always connect the positive clamp to the battery’s positive terminal first, followed by the negative clamp to a solid metal part of the vehicle’s chassis or engine block. Avoid clamping directly to the negative terminal to reduce spark risk. Never crank the engine longer than 5 seconds at a time, allowing at least one minute between attempts. Always recharge the jump starter promptly after use to maintain battery health.
