GYS chargers, starter packs and battery support units
GYS units fall into three jobs, and the right one depends on what you need the battery to do.
For charging and voltage support, the GYSFLASH 100-12 HF is a 12V battery support unit and charger. It holds a stable supply while a vehicle is on diagnostics or software updates, so the voltage does not drop mid-session. The STARTIUM 980E is a starter charger: it charges, and it can also deliver the current to start a vehicle with a flat battery.
For starting away from mains power there are portable boosters. The STARTPACK PRO 12.24C covers 12V and 24V vehicles, the STARTpack Truck is a starter and power supply for truck use, the GYSPACK 660 is a 2-in-1 starter and power pack, and the GYSPACK 900 is a 12V starter booster. The GYS Lithium Nomad Booster Power Pro 801 is a lithium booster. Other brands are in battery support units and battery tools and boosters.
Frequently asked questions
What is the difference between a battery charger and a starter charger?
A charger restores a battery over time. A starter charger can also deliver enough current to crank the engine directly, which helps when a battery is too flat to start the vehicle. The GYS STARTIUM 980E is a starter charger, so one unit covers both jobs in the workshop.
Why use a battery support unit during diagnostics?
Diagnostic sessions and software updates can run with the ignition on for a long time. If the voltage drops part way through, an update can fail. A support unit such as the GYSFLASH 100-12 HF keeps the supply voltage stable so the battery is not drained during the work.
Which GYS booster will start a 24V truck?
The STARTPACK PRO 12.24C covers both 12V and 24V. The STARTpack Truck is also built for truck starting; check its listing for the voltage and output. The GYSPACK 900 is a 12V booster, so it suits cars and vans.
Should I choose a portable booster or a starter charger?
A portable booster such as a GYSPACK or STARTPACK is for starting vehicles away from mains power, in a yard or at the roadside. A starter charger stays in the workshop and charges as well as starts.
