Frequently Asked Questions - Gyspack 660 GYS
How to recharge the internal battery of the Gyspack 660?
Place the device vertically. Connect the supplied external charger to the 230 V mains (green LED), then connect the cigarette lighter plug to the device (red LED). Charging is complete when the charger indicator turns green again. The charger can remain permanently connected thanks to the floating system.
Can the Gyspack 660 be used to start a 24 V vehicle?
No, the Gyspack 660 is designed only for 12 V batteries. Connecting to a 24 V vehicle can cause an explosion or acid projection. Check the battery voltage before any use.
What to do if the charger's red LED flashes during charging?
A flashing red LED indicates that the internal battery is damaged and can no longer be recharged. Contact GYS after-sales service for a replacement.
How to use the work light?
Press the «LIGHT» button located near the lamp. The lamp consists of 7 high-brightness LEDs. If it does not turn on, check that the internal battery is sufficiently charged.
What is the warranty period?
The warranty is 2 years from the date of purchase, covering defects and manufacturing faults (parts and labor). The internal battery is excluded from the warranty as its maintenance depends on care.
How to replace the internal battery?
Disconnect the device from the mains. Unscrew the rear housing (19 screws). Remove the retaining strap, then disconnect the + and - terminals. Replace with a battery of the same reference (53062, 12 V 28 Ah). Tighten the screws with a torque of 4 N.m.
What to do in case of an audible alarm and red LED on?
This indicates a reverse polarity when connecting the clamps. Check the battery polarity (red on +, black on ground). Set the switch to OFF before correcting the connection.
Can I use the Gyspack 660 as a continuous power source for a 12 V device?
Yes, via the cigarette lighter socket (12 V DC output). The output is protected by a 20 A thermal circuit breaker. In case of overload, the circuit breaker cuts the circuit; wait for it to automatically reset after disconnecting.
What is the lifespan of the internal battery?
The lifespan depends on maintenance. It is essential to recharge the device after each use. Storage at high temperature reduces capacity. In case of prolonged non-use, recharge before use. The battery is excluded from the warranty.
What to do if the Gyspack 660 fails to start the vehicle?
Check that the switch is on ON. Ensure the internal battery is charged (voltage > 12 V). The starting attempt should not exceed 6 seconds, with an interval of 3 minutes between attempts. If the problem persists, the vehicle battery may have another defect (alternator, spark plugs).
