The Battery Box Assembly is the primary steel enclosure that houses the vehicle’s batteries. It is fabricated from heavy‑gauge, corrosion‑resistant steel and features a durable powder‑coat finish. This assembly is designed to fit the C7H chassis perfectly, with pre‑drilled mounting holes and integrated cable routing channels to keep wiring organised and protected.
The Tension Rod is a threaded steel bar that secures the battery clamp plate to the box base, providing a strong downward force to hold the battery firmly in place. It is made from high‑tensile steel with a corrosion‑resistant coating and is adjustable to accommodate different battery heights.
The Rubber Buffer Block is a moulded elastomeric component placed between the battery and the clamping plate. It absorbs shock and vibration, protecting the battery casing from damage and reducing stress on the internal plates, thereby extending battery life.
The Rubber Mat is a full‑size sheet that lines the bottom of the Battery Box, providing a non‑slip, insulating layer between the battery and the steel floor. It prevents electrical shorts and cushions the battery against road impacts, and its raised edges contain any minor acid spills.
The Hexagon Flange Nut M8 is used with the tension rod and other M8 fasteners to secure the battery hold‑down components. Its flanged design provides a wide clamping surface and eliminates the need for a separate washer, ensuring a secure, vibration‑proof connection.
The Type 1 Hexagonal Nut is a standard M8 nut used for general fastening within the Battery Box assembly. It is manufactured from grade 8 steel with a zinc‑plated finish, providing reliable clamping force and corrosion resistance.
These heavy‑duty M14 flange bolts feature serrations under the head that provide a positive locking action, preventing loosening under severe vibration. They are used to mount the Battery Box assembly to the chassis frame, ensuring the entire enclosure remains securely attached.
The matching serrated flange nut completes the M14 fastening set, providing a self‑locking connection that resists loosening. Its flanged design distributes load evenly over the mounting surface, protecting the chassis and box structure.
The Battery Clamp Plate is a specially designed hold‑down bracket for 240Ah batteries. It incorporates an integrated mounting point for the seven‑circuit fuse box, allowing for neat, space‑saving installation. The plate is made from thick steel and is powder‑coated for durability.
The Battery Box Cover is a secure, lockable lid that encloses the battery compartment, protecting the batteries from theft, weather, and accidental short circuits. It features ventilation slots to allow gas escape and a rubber seal to keep out dust and moisture.
Our Battery Box is manufactured to Sinotruk’s original specifications, using heavy‑gauge steel and premium coatings that withstand road salt, stone chips, and extreme temperatures. It is tested to ensure it can support the weight of two heavy batteries without deformation.
The combination of rubber mat, buffer blocks, and secure clamping ensures that the batteries are isolated from chassis vibration and impacts. This extends battery service life and prevents internal plate damage, giving you reliable starts every time.
We supply every bolt, nut, rod, cushion, and clamp plate needed for a full installation. The kit includes both M8 and M14 fasteners with serrated locking features, so you have everything required to mount the Battery Box securely.
The clamp plate is designed to accept the seven‑circuit fuse box, keeping all battery connections organised and protected. This reduces cable clutter and simplifies maintenance, making this Battery Box a smart choice for modern trucks.
The Battery Box is one of the most critical structural components on any heavy truck, providing secure housing for the batteries that power the starter, lights, and all electronic systems. A poorly maintained or damaged box can lead to battery damage, electrical shorts, and even vehicle fires.
Our genuine Battery Box is designed to hold two 240Ah batteries (or a single large battery) securely in place. The steel construction is braced with reinforced corners and gussets to prevent flexing, even on rough terrain.
The tension rods and clamp plate work together to apply even pressure across the battery top, preventing movement that can cause terminal damage. The rubber buffer blocks and mat absorb road shock, reducing the risk of internal battery short circuits.
Replacing an old, corroded Battery Box with our new unit not only improves safety but also restores the correct battery position, ensuring that cable lengths are correct and that the starter and alternator wiring is not strained.
The cover is a vital part of the system, protecting the batteries from rainwater, road spray, and accidental contact with metal tools. Its lockable design deters theft and unauthorised access, adding a layer of security to your vehicle.
The M14 serrated flange bolts and nuts are specifically chosen for their superior resistance to loosening. The serrations dig into the mating surfaces, creating a mechanical lock that prevents the fasteners from backing out due to vibration.
All hardware is supplied with the correct torque specifications in the installation manual. Following these values is essential to avoid over‑tightening, which could strip threads or crack the battery casing.
We recommend inspecting the Battery Box every six months for signs of corrosion or damage. The rubber components should be checked for cracks, and all fasteners should be retorqued to the specified values.
For fleet operators, maintaining a consistent Battery Box standard across trucks simplifies battery replacement and reduces the risk of mixing different battery sizes or types, which can cause charging imbalances.
The integrated seven‑circuit fuse box mounting provision allows for neat, centralised protection of the battery circuits. This reduces the number of in‑line fuses and simplifies troubleshooting.
We back our Battery Box with a 12‑month warranty against manufacturing defects. Should any component fail, we will replace it promptly. Our technical support team is available to assist with installation queries.

Choosing a genuine Battery Box ensures that your C7H maintains its original safety and structural integrity. Aftermarket alternatives may use thinner steel or inferior corrosion protection, leading to premature rusting and failure.
The rubber buffer blocks are a unique design that conforms to the battery shape, providing maximum contact area and even pressure distribution. This reduces the risk of stress fractures on the battery casing.
