Match My Battery

Compatibility methodology

A battery is compatible only when the relevant physical, electrical and application requirements align.

Exact match

Two markings resolve to one canonical profile, or the reviewed specifications align on dimensions, chemistry, voltage and the relevant drain behavior.

Conditional match

The case and nominal voltage may align while chemistry, drain profile, capacity curve or application behavior differs. The device maker must explicitly permit the alternative.

Not compatible

A material mismatch in dimensions, voltage, terminal layout, rechargeable system or application prevents a responsible direct-replacement recommendation.

Finite publication

The catalog contains 122 canonical profiles, 220 reviewed comparisons and 78 dimension groups. It does not publish every possible pair.

Primary source registry

  1. Omnergy / Yichang Power Glory — BR2450 lithium carbon monofluoride coin-cell product specifications

    Exact unsuffixed Omnergy BR2450 example: primary Li-CFx, 3.0 V, maximum body dimensions 24.5 x 5.0 mm in its product table. Not a universal BR2450 rating, terminal tolerance or replacement approval. Marketing claims about lifetime, constant output and other chemistries are not adopted.

  2. VIDEX — VIDEX 6HR61 300mAh, index 6HR61/300/1DB/8.4V, EAN 4820118294797

    This exact product lists 8.4 V Ni-MH and 48.5 mm height, 26.5 mm width, 17.5 mm depth. These specifications do not establish every 6HR61 pack rating, device/charger approval or physical fit. General charging and cycle advice on the page is not adopted.

  3. Exell Battery — Alkaline button cells: EB-L621 and EB-L626

    Manufacturer rows EB-L621 and EB-L626 support the catalog 1.5 V alkaline examples, 6.8 mm diameter and 2.1 / 2.6 mm heights. No silver-oxide substitution or holder approval is inferred.
