Maintenance Free Car Battery Specification Example for Long-Haul Trucks: Load Rated Version

This is a worked specification for maintenance free car battery in a load rated version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The load rated version version exists because the duty cycle on long-haul trucks is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

Questions buyers ask

What is the minimum order quantity?

The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

What testing is included?

Standard lots ship with dimensional and hardness reports. DOT documentation is issued with the shipment when your market requires it.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
