Battery accessories & Booster cables
In any professional truck workshop, trailer builder or body shop, the reliability of the battery installation directly determines whether vehicles start, electrical systems function and work can be carried out safely. Battery accessories and jump start cable sets are not peripheral items but core components of every heavy vehicle electrical system. Dekoff supplies a complete range for professional buyers in the transport sector: from battery pole clamps for HGV to 24V starter cable sets, battery charge clamps and the protective covers and connection cables needed to complete the installation.
This product category covers several subcategories, each addressing a specific aspect of the battery environment in heavy commercial vehicles. Battery pole clamps form the connection point between the battery and the entire on-board electrical system of a truck or trailer. In 24V systems, which are standard in heavy transport, these clamps must withstand high current loads, vibration and the harsh conditions of both workshop use and road operation. Clamps are available for negative and positive poles, including versions designed to match the factory configurations used by specific manufacturers. For installations incorporating a main fuse in the battery circuit, single-pole clamps are available that provide direct connection to CF8-type fuse holders. Dimensional compatibility follows DIN 72331, the standard that governs battery terminal connections across the European truck and utility vehicle industry.
Battery pole clamp covers are an equally important part of the range. Once a connection is assembled, an insulating cap protects it from accidental short circuits caused by tools, foreign objects, moisture and corrosion. In a busy workshop environment where multiple technicians work around or beneath vehicles, an unprotected terminal connection represents a genuine hazard. Covers designed for cable cross-sections between 35 mm² and 70 mm² ensure that every assembled connection is properly shielded.
Battery connection cables link multiple batteries within a single vehicle system, enabling series or parallel configurations that meet the high current demands of starters, refrigeration units and hydraulic systems. Cables with cross-sections of 10 mm² or 16 mm² and pre-fitted cable eyes with M8 fixing provide low-resistance connections that remain mechanically stable under sustained load.
The battery clamp HGV subcategory includes fully insulated clamps rated up to 850 amperes. The angled design is specifically intended for engine compartments with limited access, where a straight clamp cannot be positioned correctly. Full insulation covers not only the handle but also the inner surfaces of the jaws, reducing the risk of sparking or short-circuit damage when connecting and disconnecting. This is particularly relevant at the earth connection point on a truck, where careless handling can cause immediate damage to sensitive electrical components.
Jump start cable sets represent the largest subcategory within this range. Starter cable 24V sets are available in cross-sections of 35 mm² and 70 mm², with lengths from 3.5 to 10 metres. The correct cable cross-section depends on the vehicle type and required cranking current: 35 mm² is appropriate for light commercial vehicles, while heavy tractor units, buses and agricultural machinery require 70 mm² to carry high starter currents with minimal resistance loss. Clamps are available in semi-insulated and fully insulated versions, with the fully insulated variant recommended for professional use due to the highest level of user protection. Sets with a NATO plug connection are also available, enabling use on military and government vehicles equipped with standardised NATO sockets.
Earth strips and inverters complete the supporting range. An earth strip establishes the negative battery connection to the vehicle chassis and provides a stable reference point for all consumers. An inverter enables the use of 230V tools and measuring equipment from a 12V or 24V on-board power supply, which is essential for mobile or field-based work.
For truck workshops, trailer builders, body shops and fleet operators with their own maintenance facilities, Dekoff offers a technically coherent and professionally specified range of battery accessories. Every component in this category is selected to meet the specific demands of the truck and trailer industry in terms of safety, reliability and continuous availability.
