Battery Cross-Reference & Equivalent Chart

A battery cross-reference turns one model number into every code the same cell is sold under — LR41 = AG3 = 392 = SR41, for example. Enter any number below to see the equivalent names, the factory specification of that cell and the cases where a substitute is not safe.

JavaScript is disabled in this browser, so the interactive lookup is unavailable. The full equivalent chart is printed below and every model links to its own specification page.

Equivalents & specifications

One cell, several naming systems: IEC codes are the international standard, AG and SG codes are Japanese, the three-digit numbers are US watch and calculator codes, and DL / ECR / KCR prefixes are manufacturer codes.

Typical capacity — a reference value. Request the datasheet for guaranteed minimums.

Can it be substituted?

Direct equivalent — same size, same voltage. Match diameter, thickness and voltage exactly. A cell with the same diameter but a different thickness can sit loose in its holder and lose contact.

Before you substitute

Never charge a primary cell. Every model in this table is non-rechargeable (alkaline, silver oxide, lithium manganese, carbon-zinc, zinc-air).

Data source & last review

Specifications are the factory values already published on this site (model pages) and in the EU Battery Information Files, whose document number is shown for each model. Cross-reference codes follow IEC 60086, Japanese AG/SG and US watch-code conventions. Last reviewed: 2026-10-14.

Cross-reference questions

Is LR41 the same as AG3?

Yes. LR41 is the IEC name, AG3 the Japanese name and 392 the US watch code for the same 7.9 mm x 3.6 mm button cell. In alkaline form it delivers about 32 mAh at 1.5 V; the silver-oxide equivalents run at 1.55 V nominal, so they are not chemically identical.

Can I use a different model if the voltage matches?

Only if diameter, thickness and voltage all match. A 20 mm lithium cell comes in three thicknesses — CR2016 1.6 mm, CR2025 2.5 mm and CR2032 3.2 mm — and a thinner cell may work only intermittently in a holder designed for the thicker one.

Are these batteries rechargeable?

No. Every model in this cross-reference is a primary cell: alkaline, silver oxide, lithium manganese, carbon-zinc and zinc-air chemistries here are all non-rechargeable. Charging them can cause leakage or rupture — replace the cell instead.
