GYS have a growing reputation for the quality of there  battery chargers and battery support units. One thing thats always been missing  from the range though is 24V. This has now been corrected with the launch of the The new range of battery support units for the increasing level of electronics employed in modern commercial vehicles.



The need to protect these systems when the vehicle is in the workshop is crucial. The battery support unit guarantees that voltage levels are maintained safely, especially during 'engine off, ignition on' work. Without this support, the vehicle's electronic systems operate solely from the battery, which can quickly exceed its capability. This can lead to costly damage to the ECU or other modules during diagnostic or programming operations, making the battery support unit an essential tool for technicians.
