Lithium Ion Car Battery Specification Example for Municipal Fleets: Upgraded Version
Lithium Ion Car Battery Specification Example for Municipal Fleets: Upgraded Version
This is a worked specification for lithium ion car battery in a upgraded 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 upgraded version version exists because the duty cycle on municipal fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Natural Rubber, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- shot blasting
- surface grinding
- assembly line testing
- gravity casting
- precision stamping
- die casting
Where this example applies
Programmes that run upgraded version most often specify this build for municipal fleets. Related applications include camper conversions, long-haul trucks, three-wheelers, workshop replacements, city buses.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
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.
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.
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.
What is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
