TL;DR Sealed premium AGM, Group 49/H8, 900 SAE CCA, 3-year full replacement warranty. Fits European-platform vehicles and non-PowerBoost F-150 14th gen; post-warranty service-life data not yet available.
The MTX-49/H8 is a sealed AGM in BCI Group 49/H8 (L5) with 900 SAE CCA published cleanly as the primary cranking figure. Covers European-platform vehicles (BMW, Mercedes, Audi, Volvo) and North American trucks with H8 tray space. Warranty is 3 years full replacement. Early performance is strong and the product is well-reviewed by owners; community service-life evidence past the warranty period is not yet available.
Right for non-PowerBoost F-150 14th gen owners (2021-2026 EcoBoost, V8, diesel) wanting an H8 capacity upgrade, and for European-platform owners needing 900 CCA Group 49/H8 AGM. Skip if you have the PowerBoost hybrid · the H8 physically won't fit.
Sealed AGM construction · no chemical exposure pathway in normal installation; the Prop 65 lead warning is a labeling fact on the lead hardware. Spent lead-acid batteries return through the retail core-charge system; a typical $15-$25 core charge is refunded on return.
It fits non-PowerBoost F-150 14th gen trims (2021-2026 EcoBoost, V8, diesel) as a capacity upgrade over the OEM Group 65. It does NOT fit the PowerBoost hybrid · the 48V mild-hybrid module physically occupies the H8 space in the PowerBoost engine bay. PowerBoost owners need an H7 battery instead.
Group 49/H8 (also called L5 in European nomenclature) is the standard battery size for many European-platform vehicles: BMW 7 Series, Mercedes-Benz E-Class and S-Class, Audi A6/A7/A8/Q7, Volvo XC90, and others. It also fits various Ford trucks/SUVs and GM full-size trucks with H8 tray space. Always verify against your owner's manual using your specific year and engine.
The 900 CCA figure in the product title is the SAE J537 cold-cranking amp rating · confirmed as the primary cranking-amp figure on the listing, with no PCA or other non-SAE marketing figure substituted. SAE CCA is the standard used by vehicle manufacturers for minimum specifications.
The product spec table confirms a 3-year performance warranty. The prorated extension period has not been confirmed from available sources. Note: community reports indicate warranty claims for Amazon-channel purchases may require authorization from an Interstate Battery dealer; the in-store purchase warranty process may differ.
Yes · confirmed from the product listing. It requires a minimum qualifying order or Subscribe & Save to purchase standalone. Factor this into order planning, or purchase in-store at an Interstate Battery dealer, AutoZone, O'Reilly, or NAPA.
California Proposition 65 requires a warning when a product contains lead or other listed substances. All lead-acid automotive batteries carry this warning · it attaches to the lead hardware in the battery construction, not to a chemical exposure from normal installation use.
