Who Uses the V 621 C and What It Is Used For
The Güde V 621 C is used by mechanical workshops, body shops and dealerships that need to charge, fast charge and start vehicles with 12 V batteries, such as cars and vans, and 24 V batteries, such as trucks, buses and construction machinery.
With 500 A jump-start assistance at 0 V, it offers higher performance than the V 421 C model, making it suitable for more demanding situations, including starting heavy vehicles with completely discharged batteries.
The integrated timer allows the operator to set the charging time and leave the device running independently without constant supervision. Despite its 23 kg weight, the two large transport wheels make it easy to move around the workshop.
Its Position in the Güde Range
The V 621 C is the higher model compared to the V 421 C in the professional Güde battery charger range. Compared with the V 421 C, it offers a 70 A charging current instead of 60 A, 500 A jump-start assistance instead of 390 A, a 100 A fuse instead of 50 A and an integrated timer, which is not available on the V 421 C.

Recommended Use
| Profile | Compatibility | Reason |
|---|---|---|
| Mechanical workshop with heavy 24 V vehicles and intensive work cycles | Suitable | The 500 A jump-start assistance at 0 V and 70 A charging current are suitable even for demanding vehicles. The timer allows overnight charging without supervision. |
| Dealership or auto workshop with mixed 12 V and 24 V fleet | Suitable | The 12 V / 24 V selector, 800 Ah capacity, 500 A jump-start assistance and automatic timer make it suitable for managing several vehicles during the working day. |
| Domestic use or workshop with standard charging needs | Not recommended | With a weight of 23 kg, 9,000 W mains power and 16 A fuse requirement, the V 621 C is oversized for domestic use or small standard workshops. The V 421 C is more suitable in these cases. |
Not suitable for: lithium batteries such as LiFePO4 and Li-Ion. The V 621 C is compatible only with lead-acid PB and WET batteries. It is also not recommended for domestic use where size and power are excessive, or in environments without a 230 V / 16 A power socket.

Frequently Asked Questions
The V 621 C offers a 70 A effective charging current compared with 60 A on the V 421 C, 500 A jump-start assistance at 0 V compared with 390 A, a 100 A main fuse instead of 50 A and an integrated timer, which is not available on the V 421 C.
The V 621 C is recommended for workshops with higher workloads, heavy 24 V vehicles and situations where automatic timed charging is required. The V 421 C remains a better choice for standard workshop needs and when easier handling is a priority.
No. The V 621 C is compatible only with lead-acid batteries, including PB and WET batteries. Lithium batteries such as LiFePO4 and Li-Ion require a charger with a dedicated charging profile.
Using the V 621 C on lithium batteries may cause irreversible damage and create a safety risk. Before connecting any charger to a hybrid or electric vehicle, always check the chemistry of the 12 V service battery.
The Zeitschalter is an integrated mechanical timer that allows the charging time to be set. Once the selected time has elapsed, the charger automatically stops the charging process.
This makes it useful for overnight charging or charging without constant operator supervision. The timer is also one of the main features that differentiates the V 621 C from the V 421 C.
The V 621 C uses a 100 A main fuse. The 10 spare 100 A fuses supplied with the machine are intended for replacement whenever the main fuse blows.
The fuse must always be replaced with an original 100 A fuse. Using a fuse with a different rating may compromise the protection of the main circuit.
Yes. Krollit supplies original Güde spare parts for the V 621 C, including the timer, step switch, analogue ammeter, clamps, cables and fuses.
When ordering spare parts, it is recommended to provide the serial number in order to verify the correct FSL version.
