Sealey RoadStart® 12/24V Emergency 8-Cylinder Jump Starter 6L RS105B

Heavy-Duty 12V/24V Professional Engine Starter

Every professional workshop needs a reliable jump starter that can handle the unexpected, and this unit delivers. Designed for serious use, it provides the robust power required to get a wide range of vehicles moving, from stubborn diesels to high-compression petrol engines. This isn't just a battery pack; it's a vital piece of workshop kit engineered for efficiency and safety.

Versatility for Any Job

Forget juggling multiple starters. This unit handles both **12V and 24V systems**, making it a true workhorse. For 12V vehicles, it's capable of starting 8-cylinder petrol engines up to 6L and 8-cylinder diesel engines up to 4.8L. Switch to 24V, and you can confidently tackle 6-cylinder diesel engines up to 3L. This broad compatibility means fewer delays and increased throughput in a busy garage.

Serious Starting Power

When an engine won't turn over, you need raw power. This starter delivers a substantial **3100 Peak Amps and 600A of cranking power on 12V**, dropping to 1550 Peak Amps and 300A cranking on 24V. That's enough grunt to overcome cold weather, weak batteries, or extended periods of inactivity, preventing costly call-outs or vehicle recovery.

Built for the Workshop Environment

Practicality is key. The **composite case** is durable enough for daily workshop life, and the **integral battery clamp storage** keeps leads tidy and prevents damage when not in use. A robust **carry handle** makes it easy to transport across the workshop floor or for mobile servicing. An **integral LED worklight** is a crucial addition, illuminating dark engine bays or roadside scenarios, ensuring you can connect correctly and safely.

Safety and Reliability

Protecting both the vehicle and the tool is paramount. This unit incorporates **reverse polarity and short circuit protection**, safeguarding against common connection errors. An **inbuilt fusible link protection system** adds another layer of security, giving you peace of mind. The supplied mains charger features an **automatic cut-off**, preventing overcharging and extending the lifespan of the internal battery.

Beyond Starting

More than just a starter, this unit features **two 12V power sockets**. These are incredibly useful for powering auxiliary equipment like diagnostic tools, inspection lamps, or small air compressors, making it a truly versatile piece of equipment for any mechanic. The front panel also displays the **internal battery charge level**, so you always know when it's ready for action.Composite case with integral battery clamp storage and carry handle.
