Read before buying

Specifications are the manufacturer's published values (2026-09) and should be re-confirmed for current production runs.
CCA figures follow the standard stated with the value; values from different standards are not directly comparable (see CCA vs CA).
Group size decides physical fit, not performance — match the group first, then the ratings (see group sizes).

Our Read

My read: This page presents the product as the manufacturer publishes it — the commercial section's role is structured access and honest context, not promotion. Where a value is missing, it is marked "per manufacturer quotation" rather than guessed.

Why: B2B battery sourcing lives and dies on spec accuracy. A catalogue that invents numbers is worse than one that admits a gap, so this section states its sources and its omissions side by side.

Editorial note — commercial section; specifications are the supplier's published values, not independently verified.
