The 800 Ah capacity covers almost all batteries fitted to heavy commercial vehicles. With 390 A of jump-start assistance at 0 V, it can start vehicles with a completely flat battery. The two 50 A fuses included in the rectifier and the 10 spare fuses make the device immediately operational without additional purchases.

Güde does not cover this type of use under warranty.

Jump-start at 0 V delivers 390 A and enables starting even with completely flat or partially short-circuited batteries.\u003c\/p\u003e\n  \u003cp\u003eIn a workshop, the 0 V function is essential for heavy vehicles (trucks, buses) that arrive completely dead after extended downtime. Pre-charging (65–100 Ah) before starting reduces stress on the rectifier and extends its service life. The Güde manual states that continuous jump-start assistance must not exceed 15 seconds without a cooling pause of at least 3 minutes.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eHow do you select the voltage between 12 V and 24 V on the V 421 C?\u003c\/summary\u003e\n  \u003cp\u003eSelection is made via the dedicated toggle switch (spare part code 85074-01016 — 12 V\/24 V connector complete). At 12 V, the unit works on passenger cars and light vehicles; at 24 V on heavy commercial vehicles, buses and construction machinery.\u003c\/p\u003e\n  \u003cp\u003eAlways verify the battery's rated voltage before connecting the charger. The reverse polarity protection activates if the terminals are connected incorrectly, but does not replace prior voltage verification: connecting a charger set to 24 V to a 12 V battery can damage it within seconds if the protection does not activate in time.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eHow often should the fuses on the Güde V 421 C be replaced?\u003c\/summary\u003e\n  \u003cp\u003eThe 10 spare 50 A fuses included in the equipment are intended for replacing the two rectifier fuses (code 85074-01005) and the fuse holder (code 85074-01007). Rectifier fuses must be replaced every time they blow, without exception.\u003c\/p\u003e\n  \u003cp\u003eGüde recommends not replacing fuses with values other than the original 50 A: a fuse with a higher rating does not adequately protect the rectifier, which is the most costly component (code 85074-01004). Fuse replacement is the first maintenance operation to carry out before any other diagnosis in the event of no current output.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eAre original Güde spare parts for the V 421 C available from Krollit?\u003c\/summary\u003e\n  \u003cp\u003eYes.
