5 functions in a single device
What the Gysflash 100-12 HF does
Beyond standard charging, the device meets the common needs of a diagnostic and reprogramming workshop.
1. Battery Holder
Powers the 12V automotive battery (liquid or gel) during diagnostics or reprogramming, without risk of discharge during the process.
2. Advanced charger
Applies a charge cycle suited to the maintenance of batteries in recent vehicles.
3. Showroom Mode
Maintains the battery of an exhibited vehicle by compensating for its self-discharge, with setting lock.
4. Battery replacement
Maintains vehicle electrical power to preserve memory settings during replacement.
5. Regulated power supply
Adjustable voltage and current, to precisely meet the needs of the intervention.

Constant tension while writing a calculator
During an ECU remap using a tool like KESS3 or AutoTuner, a voltage drop during the writing process can corrupt the ECU. The Gysflash 100-12 HF maintains a stabilized voltage throughout the operation, regardless of the vehicle's electrical demand.
The battery change mode also secures a frequent workshop operation: replacing a battery without losing the vehicle's stored settings (radio, seats, engine parameters).
