Automotive Batteries Attributes

Automotive batteries in the aftermarket are 12 V SLI (starting-lighting-ignition) lead-acid units in flooded, EFB, and AGM construction, sold by warehouse distributors and jobbers to installers, fleets, and DIY counters. Nobody buys them by brand. They buy the group size the vehicle takes, then compare CCA, reserve capacity, and warranty inside that bucket.

The data is hard because this is a fitment problem wearing a spec sheet's clothes. One footprint carries three names (BCI 48, DIN H6, EN L3) and suppliers send whichever their home market uses. CCA is published under SAE, EN, and IEC test methods that give different numbers for the same battery, and the carton usually prints the digits without the standard. Group size pins the case footprint and polarity, but height over terminals, hold-down ledge, and vent port live on a drawing, not in a table.

The same cell stack then ships under a dozen private labels with different MPNs, ACES fitment has to be maintained per vehicle-year, and core charge and UN2794 classification sit in the ERP rather than the product record.

Core

Every SKU needs these. Without them the record is not a product, it is a row.

BCI Group Size
enum
48 (H6)

The primary filter. Fixes case footprint, nominal terminal layout, and the hold-down interface for the vehicle's tray. Every buyer starts here.

Battery Technology
enum
AGM

Flooded, EFB, and AGM are not interchangeable on start-stop vehicles. Determines charge acceptance, cycle life, and whether the BMS needs re-registering.

Cold Cranking Amps (CCA)
number · A
760

Current delivered for 30 s at -18 C without dropping below 7.2 V. The number every buyer sorts on, and the one the OE spec sets a floor for.

Reserve Capacity (RC)
number · min
120

Minutes at 25 A to 10.5 V at 27 C. Sizes how long accessories, telematics, and key-off loads survive a dead alternator. Fleet buyers weight this over CCA.

Terminal Type
enum
Top post (SAE tapered)

Top post, side terminal, stud, or dual. Wrong terminal means the OE cable will not land, even when the case drops cleanly into the tray.

Positive Terminal Position
enum
Positive right (front face)

The only difference between group 24 and 24F, or 34 and 34R. Reversed polarity leaves the cable a foot short of the post.

Case Dimensions (L x W x H)
text · mm
278 x 175 x 190 (L x W x H)

BCI allows tolerance inside a group and private-label cases drift within it. Tray fit and clamp travel depend on the real number, not the group nominal.

Manufacturer Part Number (MPN)
identifier
48AGM

Anchors cross-reference across private labels, ACES fitment, and core return. The same cell stack ships under a dozen brand part numbers.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

Amp-Hour Capacity (C20)
number · Ah
70

20-hour capacity. The rating European and JIS datasheets lead with, and the one buyers cross-checking a DIN-coded OE battery ask for by name.

Cranking Amps (CA / MCA)
number · A
950

Same discharge run at 0 C instead of -18 C, so it reads roughly 20-25% higher than CCA. Suppliers print it on the carton; it must not land in the CCA field.

Height Over Terminals
number · mm
199

Case height plus post height. Governs hood, tray-cover, and trunk-panel clearance on top-post SKUs. Group size does not constrain it.

Vent Port Configuration
enum
Side vent port, both ends, 6 mm nipple

Trunk, under-seat, and cabin installs need a vent nipple and a hose route. An AGM with no port cannot replace a vented OE battery.

Hold-Down Type / BCI Assembly No.
enum
Base hold-down, 3/4 in ledge

Base ledge, top frame, or stud. The BCI assembly number encodes cell layout, hold-down, and polarity in one code the tray has to match.

Warranty - Free Replacement Period
number · months
36

The counter's second question after price and a live filter on retail rails. The prorated tail is a separate number and should not be merged in.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

CCA Test Standard
enum
SAE J537

Qualifies the CCA number. SAE J537, EN 50342-1, and IEC 60095 use different durations and voltage floors, so the digits alone are not comparable.

UN/DOT Shipping Classification
enum
UN2794, Class 8 (wet, filled with acid)

Wet flooded, wet non-spillable (AGM), and lithium ship under different UN numbers and packaging rules. Drives carrier acceptance and marketplace clearance.

GTIN / UPC
identifier
0-40001-23456-7

Required by every marketplace and by the PIES item record. Private-label SKUs frequently reuse a supplier GTIN across two brands, which breaks listings.

Country of Origin
enum
United States

Drives duty, marking, and government and fleet bid eligibility. Cell and assembly origin can differ; the record should carry the assembly country.

The fields that aren't in the schema at all

What most automotive batteries catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Supplier signal
+ CCA Test Standard (SAE / EN / IEC)

The same DIN-coded battery shows 760 A on the supplier's EU datasheet and 950 A on the US carton. Both land in one CCA column, and neither record says which test produced the number.

A CCA >= 800 filter silently drops EN-rated SKUs that outperform the SAE-rated ones it returns. Cross-reference tools then rank the better battery lower.

Review signal
+ Height Over Terminals

Returns on top-post replacements cite hood and tray-cover clearance, not performance. Group size pins case height; post height sits on the dimensional drawing and no catalog carries the field.

Battery goes in, hood will not close, unit comes back opened and non-restockable. The core is now the distributor's problem instead of the customer's.

Search signal
+ Vent Port Configuration

Buyers search 'AGM battery with vent tube' and 'vented battery trunk install' and land on AGM SKUs with no vent field, so the rail returns everything and filters nothing.

Trunk and under-seat fitments get an unvented AGM, the installer refuses it at the bay, and the counter eats a return plus a second delivery.

Competitor signal
+ Core Charge / Core Return Group

Retail PDPs show the core charge on the battery line. Distributor product records carry it only in the ERP price file, so the web catalog and the quote disagree.

Quoted price is wrong at the cart, the invoice surprises the fleet buyer, and statutory deposits (CA, SC, ME) get handled by hand at the counter.

Competitor signal
+ Start-Stop Standard (SAE J3012 / EN 50342-6)

Competitor rails expose a Start-Stop filter. Most catalogs carry only Technology = AGM, which sweeps in AGM SKUs never qualified for stop-start cycling duty.

A non-stop-start AGM sold into a stop-start car fails inside the free-replacement window and comes back as warranty, not as a return.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way automotive aftermarket suppliers spell it. A filter only works once they agree.

Battery Technology
AGMAbsorbed Glass MatVRLA / AGMSealed AGMMaintenance FreeDry Cell
AGM

'Maintenance Free' and 'Dry Cell' get printed on flooded, EFB and AGM alike. They are marketing words, not a technology value.

BCI Group Size
48H6Group 48/H6L3LN348 (DIN H6)
48

BCI 48, DIN H6 and EN L3 describe one footprint. Left as sent, the same battery splits across four filter buckets.

Cold Cranking Amps (CCA)
760 CCACCA: 760A760 A (EN)Cold Crank 760760A @ 0FEN 760 / SAE 950
760 A, standard = EN 50342-1

Digits and test method have to split into two fields, or the US and EU sheets for one battery look like two different products.

Terminal Type
Top PostSAE PostStandard PostTop/Side DualDual TerminalGM Side Post
Top post (SAE tapered)

Dual-terminal SKUs get filed as 'Top Post', so side-terminal fitments never surface them on the rail.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

  • Will it drop into my tray and take the stock hold-down, or do I need a different group?
  • Is the positive post on the left or the right when I'm looking at it?
  • That 760 CCA - is that an SAE number or an EN number?
  • Car has start-stop. Do I need AGM, or will an EFB cover it?
  • Battery's in the trunk. Does this one have a vent port for the hose?
  • Will the posts clear the hood, or is this taller than what came out?
  • What's the core charge, and can I bring the old one back here?
  • Truck runs a winch and a light bar - what's the reserve capacity?

Automotive Batteries data, in practice

Is BCI group size enough to guarantee fit?

No. Group size fixes the case footprint, nominal terminal layout, and polarity, which is what separates 24 from 24F and 34 from 34R. It does not fix height over terminals, hold-down ledge type, or vent port. A group 48 AGM with a taller post shroud will drop into the tray and still foul the hood or the tray cover. BCI also allows dimensional tolerance inside a group, and private-label cases drift within it. Carry real case dimensions, height over terminals, hold-down type, and vent configuration as their own fields. Group size is the filter, not the fit.

Should CCA, CA, and MCA live in the same field?

No. They are three tests at three temperatures. CCA (SAE J537) is 30 s at -18 C to a 7.2 V floor. CA, which marine sheets call MCA, is the same discharge at 0 C, so it reads roughly 20-25% higher. HCA runs at 27 C and reads higher still. Suppliers print whichever number is largest on the carton. Merged into one CCA column, a 950 CA battery outranks a 760 CCA battery that is genuinely stronger. Keep one field per rating, plus a separate field naming the test standard, because SAE J537, EN 50342-1, and IEC 60095 disagree on both duration and voltage floor.

AGM or EFB for a start-stop vehicle?

Take the vehicle's OE spec, not the cheaper one. EFB is the entry stop-start chemistry, qualified under SAE J3012 and EN 50342-6, with carbon-enhanced negative plates for partial-state-of-charge duty. AGM handles higher cycle counts and regenerative-braking charge acceptance, and vehicles that shipped with AGM generally need AGM back. Downgrading AGM to EFB shortens life inside the free-replacement window. Note also that plain 'AGM' does not mean stop-start qualified; AGM is sold for both stop-start and conventional applications. On most European platforms the replacement also has to be registered to the BMS, or the charge strategy keeps running the old battery's profile.

Where does this data actually live?

Spread across five places. Group size, CCA, and warranty are on the carton and in the price sheet. Reserve capacity and Ah are usually on the supplier datasheet. Height over terminals, hold-down ledge geometry, vent port location, and terminal centres are on the dimensional drawing, often a PDF with no text layer. The CCA test standard is a footnote, if it is stated at all. Core charge and UN2794 classification sit in the ERP, not the product record. ACES fitment arrives as a separate per-vehicle-year file on its own release cadence. Nothing consolidates them; the consolidation is the job.
