JoltNapo

JoltNapo is designed for versatility. Whether you have a car in London, a motorcycle in the Midlands, or a motorhome parked in the Lake District, it works with 12V and 24V batteries including LiFePO4, AGM, and GEL types.

The pulse repair mode is a dedicated feature designed to desulphate and recover aged or idle batteries. It can often revive a battery that basic chargers would simply report as dead, saving you the cost of a replacement.

Absolutely. The 7-stage system includes a 'Float' mode specifically for maintenance. It monitors the voltage and provides just enough charge to keep the battery healthy without overcharging, making it ideal for classic cars or seasonal vehicles kept in a garage.

JoltNapo features automatic temperature compensation. It detects the ambient temperature and adjusts the charging voltage accordingly—increasing it in freezing UK winters and decreasing it during summer heatwaves to prevent damage.

The backlit LCD shows real-time voltage, charging current, progress percentage, and internal temperature. It makes it very easy to see exactly how your battery is performing at a glance.

We offer a 30-day satisfaction guarantee for all UK customers. If the JoltNapo doesn't meet your expectations for reviving or maintaining your batteries, our UK-based support team will arrange a simple return.

Safety is built-in. It includes protection against reverse polarity (if you mix up the clips), short circuits, overheating, overcurrent, and overvoltage, ensuring your vehicle's electronics are always safe.
