Maintenance Free Car Battery Specification Example for Aftermarket Retail: Standard Replacement

This is a worked specification for maintenance free car battery in a standard replacement 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 standard replacement version exists because the duty cycle on aftermarket retail is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

Questions buyers ask

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.

How long does sampling take?

Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.

What happens if a lot fails inspection?

The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.

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.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
