Around a quarter of all vehicles are brought into the workshop with an undercharged battery. This is why premature battery failure during maintenance or repair is a common occurrence. This is neither productive nor profitable for the workshop. The PRO25 charges, overhauls and restores 12-volt batteries of all types. And it does so quickly, safely and without disrupting the maintenance or repair process. The device is also the perfect power source for diagnostics and troubleshooting and protects important configuration data if the battery has to be disconnected from the vehicle.

In the car showroom, the PRO25 is a powerful yet lightweight and portable solution for battery backup. It is safe and easy to use and quiet enough to be placed under the vehicle.
