Battery Reference Guide: Cross Reference Charts, Key Fob Finder, Device Lookup and More
Finding the right replacement battery should not require a degree in electronics. Whether you are trying to match a watch battery across brands, figure out which coin cell goes in your car key fob, or track down the right battery for a garage door opener, the numbering systems can be a maze. A 377 from Renata is the same as an SR626SW from Sony, which is the same as a V377 from Varta.
That is why we built our Battery Reference Guide, a free interactive tool with everything you need in one place.
Cross Reference Chart
The heart of the guide is our coin cell cross reference chart covering 55 batteries across 7 major brands: Renata, Energizer, Panasonic, Sony/Murata, Maxell, Varta, and Rayovac. Search by any part number, filter by chemistry type (silver oxide, lithium, or alkaline), and sort by voltage, diameter, or height. Every row has a shop button that expands to show the exact products we carry with direct links to buy, plus pack sizes so you know what you are ordering.
Key Fob Battery Finder
Not sure which battery your car remote takes? Our Key Fob Battery Finder covers over 35 vehicle brands and 295 models. Just select your make, model, and year, and the tool shows you the correct battery along with links to order it from our store. We cover everything from Acura to Volvo, including popular models like the Toyota Camry, Honda CR-V, Ford F-150, and BMW 3 Series.
Battery Finder by Device
Beyond key fobs, our Device Finder helps you identify the right battery for watches, garage door openers, calculators, medical devices, toys, flashlights, smoke detectors, fitness scales, and smart home products. Pick a category, find your specific device or brand, and see the battery type instantly. We cover popular names like Casio G-Shock, Chamberlain garage openers, Texas Instruments calculators, and Apple AirTags.
Battery Size Comparison
Sometimes you just need to see the difference. Our visual size comparison shows watch batteries, lithium coin cells, and standard batteries (AA, AAA, C, D, 9V) in correct proportions to each other, so you can tell at a glance how a CR2016 compares to a CR2032 or where a 377 falls next to a 390. Every battery in the chart links directly to our store.
Custom Battery Packaging
Need batteries packaged under your own brand or in specific quantities for resale? We offer custom coin cell battery packaging for retailers, OEMs, and businesses of all sizes. From private label tear strips to bulk branded packs, we can build a solution that fits your needs. Learn more about custom packaging.
