How to use Battery Equivalents & Cross-Reference
- Type a battery code like LR44, 357, or CR2032
- See every interchangeable brand and standard name for that cell
- Check its size, voltage, chemistry, and any fit warnings
About Battery Equivalents & Cross-Reference
A single battery can go by a dozen names, and that is exactly where swaps go wrong. This cross-reference lets you type any code — LR44, 357, AG13, LR1130, LR41, AG3, SR626SW, 377, CR2032, A23 and more — and see every interchangeable brand and standard name for that exact cell, along with its size, voltage and chemistry. Instead of a flat chart you scroll through, it groups all the aliases for one physical battery together, so you can confirm a match at a glance.
It covers the codes people hunt for most: the button and coin cells in toys and key fobs, the small silver-oxide watch batteries like SR626SW and 377, and the AG-series alkaline naming (AG3, AG13) that maps onto the SR and LR numbers. Look up the battery in front of you, or the one a device is asking for, and the tool shows what it is equivalent to across the alkaline, silver-oxide and lithium lines.
Crucially, it flags where "fits" does not mean "safe." Two cells can share a size but differ in voltage or chemistry — a rechargeable lithium in place of a primary cell, or a 1.5 V alkaline where a device wants a steadier 1.55 V silver-oxide — so each group notes those differences rather than pretending every same-size cell is a drop-in. There is nothing to install and no sign-up. Every lookup runs entirely in your browser, so nothing you type is uploaded anywhere.
Look up a battery to see the equivalent codes that fit the same slot — a quick cross-reference chart.
Frequently asked questions
- What is equivalent to an LR44 battery?
- The same 11.6 x 5.4 mm cell is sold as AG13, A76, L1154 and GPA76 (alkaline), and as 357, SR44 and 303 (silver-oxide). Silver-oxide holds a steadier 1.55 V, which is better for meters and calipers.
- Is a 357 battery the same as an LR44?
- They are the same size and swap physically. The difference is chemistry: 357/SR44 is silver-oxide (1.55 V, flatter discharge) and LR44 is alkaline (1.5 V) — either works in most toys, but precision devices prefer silver-oxide.
- What battery types can I look up in this chart?
- Button and coin cells across the three common chemistries: alkaline (LR and AG codes), silver-oxide (SR codes) and lithium (CR and rechargeable LIR codes). That spans tiny watch cells up to CR2032 and A23 — type the number printed on your battery or in the device manual and you get its full equivalent group.
- What is a watch battery like SR626SW or 377 equivalent to?
- 377 and SR626SW are two names for the same 6.8 x 2.6 mm silver-oxide watch cell, also sold as SR626, D377 and V377. Its alkaline counterpart is AG4/LR626, which is cheaper but drops voltage faster, so most watches stick with the silver-oxide version.
- What is an LR1130 battery equivalent to?
- LR1130 is the alkaline cell also called AG10, 189 and L1131. The silver-oxide equivalent in the same 11.6 x 3.1 mm size is SR1130, sold as 389 and 390 — it holds 1.55 V versus the LR1130's 1.5 V, which matters in watches and laser pointers.
- What is an LR41 battery equivalent to?
- LR41 is the alkaline cell also known as AG3, 192 and L736. Its silver-oxide twin is SR41, sold as 384 and 392. All share the same size and swap physically; the silver-oxide versions give a flatter 1.55 V discharge.
- What do the AG battery numbers like AG3 and AG13 mean?
- AG is a simplified alkaline naming scheme, so each AG number maps to a standard LR (and often SR) code: AG3 is LR41, AG4 is LR626, AG10 is LR1130 and AG13 is LR44. Type any AG number into the tool and it shows the matching LR/SR equivalents and voltage.
- What is an AG13 battery equivalent to?
- AG13 is the same cell as LR44, A76, 357 and SR44 — see the LR44 group in the tool for the full list.
- Can I use a CR2032 in place of an LIR2032?
- Be careful — they are the same size but a CR2032 is a 3.0 V primary (single-use) cell and an LIR2032 is a 3.6 V rechargeable. Putting a 3.6 V rechargeable where a 3.0 V primary belongs can damage the device, and a CR2032 must never go in a charger.
- Can I get a printable or PDF version of the chart?
- There is no fixed PDF to download, but you can look up any code on screen and use your browser's Print command (Ctrl+P or Cmd+P) to save that result as a PDF or print it. That way you get exactly the batteries you searched for rather than a huge generic table.
- Is it always safe to swap equivalent batteries?
- Only when the size AND voltage match. Physically fitting is not enough — check the voltage and chemistry, and never substitute a rechargeable lithium cell for a primary one of the same size.
