Battery clamp set GEKO G02403 800A, 2-piece self-locking jumper cable clamps

Set of two GEKO self-locking battery clamps G02403 rated 800A, designed for reliable temporary electrical connections to vehicle batteries. These metal clamps feature a self-clamping mechanism that maintains firm contact on battery terminals and jumper cable conductors. The set is intended for tasks such as battery jump-starting, battery testing and short-term power links where a strong conductive grip is required.

Advantages

The clamps offer a high 800A current rating for effective current transfer during jump-start procedures. Their self-locking jaws provide stable mechanical grip that reduces the risk of accidental detachment while connected. Constructed from conductive metal with insulated handles, the clamps combine electrical conductivity with user protection against accidental contact. The two-piece format supplies both positive and negative connections required for standard automotive use.

Suitable for

• Automotive jump-starting and emergency starts
• Battery testing and voltage checks
• Temporary power connections for 12V systems
• Workshop use for maintenance and diagnostics

Key specifications

• Quantity: 2 clamps
• Rated current: 800 A
• Construction: metal conductive jaws with insulated handles
• Connection type: self-locking / spring-actuated clamping mechanism
• Intended system voltage: typical for 12 V vehicle batteries

How to use

Ensure both vehicle ignition and any connected electrical systems are switched off before attaching the clamps. Identify the positive and negative terminals of the battery and attach one clamp to each terminal, ensuring firm metal-to-metal contact on clean terminal surfaces. The self-locking jaws will hold the clamps in place; verify that insulation on the handles prevents accidental contact with conductive parts. After completing the jump-start or testing procedure, remove the clamps in reverse order and store them in a dry location.

Usage recommendations

Inspect terminals and clamp jaws for corrosion or dirt prior to use to ensure good contact. Do not use the clamps on live high-voltage systems beyond typical 12V automotive applications. Wear appropriate hand protection when handling clamps and avoid short-circuiting the clamps across battery terminals.
