It is designed for vehicles with 12 V batteries (GYSCAP 680E) or 24 V batteries (two 12 V batteries, GYSCAP 24V).
Charging through the cigarette lighter socket takes up to 30 minutes for both GYSCAP devices.
If two attempts fail, the vehicle fault may not come from the battery; find and confirm the cause before retrying.
BYPASS mode is used when standard troubleshooting and a charging attempt fail and the vehicle computer may not start because battery voltage is below 8 V for a 12 V battery or below 16 V for a 24 V battery.
