High Performance Car Battery Specification Example for Passenger Cars: Vented Design
High Performance Car Battery Specification Example for Passenger Cars: Vented Design
This is a worked specification for high performance car battery in a vented design 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 vented design version exists because the duty cycle on passenger cars is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

Example specification
| Item | High Performance Car Battery |
|---|---|
| Application | Passenger Cars |
| Version | Vented Design |
| Base material | Zinc Plated Steel |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | painted |
| MOQ | 2,000 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | ECE R90 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Zinc Plated Steel, 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
- die casting
- assembly line testing
- sintering
- anodising
- precision stamping
- ultrasonic cleaning
Where this example applies
Programmes that run vented design most often specify this build for passenger cars. Related applications include emergency vehicles, camper conversions, agricultural trailers, light trucks, scooter fleets.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 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
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
What is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
