Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The build starts from passenger vehicle production and parc volumes by powertrain type, split between internal combustion, start-stop, mild-hybrid and hybrid electric, and applies a realised battery price per unit for each chemistry and voltage class, distinguishing OEM fitment from aftermarket replacement. Aftermarket volume is derived separately from average replacement intervals applied against the installed vehicle parc by region. This bottom-up build is then checked against disclosed revenue and shipment figures from the largest lead-acid and lithium-ion suppliers named in this report. Where a chemistry's bottom-up volume implied a unit price inconsistent with supplier disclosures, the unit-price assumption was corrected rather than the volume input, since production and parc data are the more reliable of the two.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Interviews target procurement and category managers at vehicle manufacturers who set battery specifications and dual-source agreements, plant-level purchasing contacts at the largest cell and plate producers, and channel managers at automotive parts distributors who see replacement demand directly. Regulatory contacts are included where start-stop or emissions requirements shape specification timing. Sampling emphasises China, the United States, Germany and Japan, reflecting where vehicle production and battery manufacturing are most concentrated, with additional coverage in India and Brazil to capture faster-growing aftermarket demand in expanding vehicle parcs outside the largest manufacturing hubs.

Secondary sources, this report

Desk research draws on national vehicle registration and production statistics published by regional automotive associations, harmonised customs codes covering battery imports and exports, and type-approval and emissions filings that record start-stop and mild-hybrid fitment rates by market. Company filings and investor disclosures from the largest listed battery manufacturers are used to check unit pricing and shipment volumes. Trade-body benchmarks on replacement battery life and warranty claims inform the aftermarket replacement-interval assumptions used in the bottom-up build. Battery chemistry patent filings and industry association technical standards are reviewed to confirm which voltage classes and chemistries are commercially available in each forecast year.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built on the pace at which start-stop and mild-hybrid fitment become standard equipment across new vehicle production, the rate at which hybrid electric vehicle output grows within total passenger vehicle output, and the price trajectory of lithium-ion and emerging sodium-ion cells relative to lead-acid. Replacement-cycle volume is projected forward from the existing vehicle parc as lifespans lengthen for several chemistries, not held constant at historical rates. For the forecast to hold, start-stop and mild-hybrid mandates already in force need to remain in place, and lithium-ion cell costs need to keep declining at a pace consistent with recent years.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Historical output for 2020 through 2024 was checked against recorded vehicle production and registration growth by region to confirm the base build tracks actual market movement rather than a smoothed trend. Segment share shifts, particularly the pace at which lithium-ion displaces lead-acid and hybrid electric vehicles displace conventional internal combustion output, were reviewed against analyst commentary from the named manufacturers' own disclosures. Sensitivities were tested on the pace of start-stop mandate adoption and on lithium-ion cost decline, since both assumptions move the forecast total the most if they run faster or slower than modelled.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is strongest for lead-acid and lithium-ion volumes in the largest manufacturing markets, where production and registration data are detailed and frequently updated. It is weaker for sodium-ion, which is still moving from pilot to volume production and has limited disclosed shipment history, and for aftermarket volume in markets with less formal vehicle parc data. A structural risk that would force a revision is faster-than-modelled full battery-electric substitution in markets currently forecast to retain a large hybrid or internal combustion share, which would reduce demand for the chemistries and applications sized here.
