About BatteryCross
BatteryCross answers one question: the code on your cell has stopped appearing on shelves, so what goes in its place, and what will that cost the thing it powers. Fit and voltage are answered separately, because they are different questions and merging them is how a cross-reference table misleads.
Who publishes it
BiLingoPlus LLC, a limited liability company registered in the State of Wyoming, United States. There is no invented author persona here and there will not be one: the pages are generated by a program the company writes and maintains, and the company is accountable for them. The site is independent and is not affiliated with, endorsed by or connected to any battery manufacturer or standards body.
Where the numbers come from
Dimensions, voltages, chemistries, capacities, impedances and operating ranges are published by the manufacturer and reproduced without change. This snapshot holds 215 designations assembled from 419 catalog records, taken on 01 September 2026 and pinned: the site is rebuilt deliberately, not on a schedule, so a page does not change under a reader without the date changing with it. Every cell page carries numbered references to the exact records and data sheets behind it.
Everything else is arithmetic on those figures and is marked as ours: whether one cell fits where another sat and in what sense, how far apart two voltages are and what that costs, stored energy and energy per cubic centimeter, the rank within an envelope, and the check of a designation against its measured size. The method page states each rule and the tolerance it uses.
What it does not do
It reads one manufacturer's catalog. It sells nothing, quotes no prices and carries no affiliate links. It is not engineering advice and not a safety certification: a cell that fits a compartment is not always a safe substitute, rechargeable cells are never a drop-in for primary cells, and where the equipment is medical or a safety device its own manufacturer names the cell. Pages say what the catalog does not contain rather than claiming the world does not contain it.
Corrections
If a figure here does not match the manufacturer's published data, write to hello@batterycross.com with the page and the row. Source figures are parsed mechanically, so a mismatch is a bug in our reader and we want it. If a substitution suggested here turned out to be wrong in practice, we especially want that. Corrections are made in the source data and the whole site is rebuilt, so a fix reaches every page that used the figure.
Reuse
The underlying figures are facts and not our property. The complete snapshot is published as a dated CSV so that anyone can check us against it or build something else with it. The text, the computed comparisons, the drawings and the arrangement are ours; quote them with a link.
