I was about to buy a new battery for my Land Rover after it sat all winter. The JoltNapo Repair mode brought it back to life in 8 hours. Saved me over £150!

Absolutely brilliant bit of kit. The LCD screen is so clear and it's small enough to keep in the boot. Used it on my motorbike and my husband's van with no issues.

Finally a charger that supports LiFePO4 batteries without costing a fortune. The temperature compensation is perfect for the cold mornings up here in Scotland.
