GYS (7)

GYS produces workshop-grade battery chargers and starter units built for regular commercial use rather than occasional domestic charging. Truckstop Group stocks the GYS range, including automatic chargers, starter chargers capable of starting AGM and Gel Stop-Start batteries, and high-power stabilised power supply units used for battery support and diagnostic work. Output capacity and charging profile both need to match the battery types and workshop workload before choosing a unit. A unit sized for occasional light use will struggle in a busy workshop cycling through multiple vehicles a day.

Shop GYS battery chargers at Truckstop Group

GYS charging equipment is built for the demands of daily workshop use rather than occasional home charging, covering everything from automatic maintenance chargers that keep a battery topped up without overcharging, through to high-current starter chargers capable of safely starting modern AGM and Gel Stop-Start batteries.

Battery support functions on units like the GYSFLASH range serve a different purpose to charging: they provide a stabilised power supply during diagnostic or reprogramming work, keeping the vehicle's electrical system at a steady voltage while the main battery is disconnected or under load from diagnostic equipment. This matters increasingly as more vehicles need a stable power supply during software updates.

Choosing the right GYS unit depends on the battery types a workshop typically handles and the volume of charging or starting work involved. A unit sized for occasional light use will struggle in a busy workshop cycling through multiple vehicles a day.

Frequently Asked Questions

What's the difference between a battery charger and a starter charger?

A standard charger tops up a battery over time. A starter charger can deliver enough current to start a vehicle directly, which is useful when a battery is too depleted to start the engine on its own.

What is a GYSFLASH battery support unit used for?

It provides a stabilised power supply during diagnostic or reprogramming work, keeping the vehicle's electrical system steady while the main battery is disconnected or under load from diagnostic equipment.

Can GYS chargers handle AGM and Gel Stop-Start batteries?

Yes, units like the STARTIUM range are designed to safely charge and start AGM and Gel Stop-Start batteries, which need a different charging profile to conventional flooded lead-acid batteries.

Which GYS unit suits my workshop?

This depends on the battery types you work with and your typical workload. Call our team if you'd like help choosing the right unit.
