Changing your Watch Battery is a pain!
It seems the cheaper the Watch, the harder it is to change. And what makes it even more difficult is the fact that there are hundreds of different Watch Batteries. They come in different thicknesses, sizes, widths, it causes a lot of confusion and frustration. What’s even funnier is the fact that a lot of Watch Batteries (or Cells) look alike, but aren’t!
How is anyone supposed to know what’s the correct size for your Watch? Pull out your old dead battery from your Watch and look at it. Chances are, there’s a lot of gibberish on that battery. And some Watches sold in department stores don’t even list a battery number on them at all! ??? How’s that supposed to help you?
So what can you do to find the correct battery that fits your Watch?
(You can get some great deals on Watch Batteries from Amazon Here!)
Below is a Conversion Chart for the most common Watch Battery types. Both Regular (Silver Oxide & Mercury) and Lithium Battery Watch Cells. Take your Watch Battery Number, and look it up on the chart to locate its conversion number. Then go into any Jewelry Store and buy one. (Just about any Store, Jewelry or not, will sell Watch Batteries!)
Note: There are some batteries that will work for multiple Battery Numbers. So if they’re out of one battery, you can always use the other! I’ll list these at the end of the blog!
Here they are. The most common Watch Batteries, their Conversion Numbers and Voltage.
(Also note that Energizer is probably one of the most common brands of Watch Batteries sold! P.S. 364 & 379 are the two most popular Watch Batteries there are, so expect stores to be out of these! (Of Course!)
This Chart Converts Batteries and Voltage (most are 1.5 or 1.35 Volts) for Everready, Energizer, Duracell, Maxell, Panasonic, and Varta. And Coverts Battery Cell Numbers: 301, D301, SR43SW, SP301, V301, 303, D303, SR44SW, SP303, V303, 309, D309, SR754SW, WS6, V309, 313, D313, NP313, V313, 314, SR716W, 315, D315, SR716SW, V315, 317, D317, SR516SW, SP317, V317, 319, D319, SR527SW, SP319, V319, 321, D321, SR616SW, SP321, V321, 323, D323, WH-6, V323, 325, D325, WH-1, V325, 328<, 329, D329, SR731SW, V329, 333, SR610SW, 335, SR512SW, SP335, 337, SR416SW, SR416SW, 339, SR614SW, V339, 341, V341, 343, D343, NP343, V343, 344, D344, SR1136SW, WS12, V344, 350, D350, V350, 354, D354, V354, 357, D357, SR44W, SP357, V357, 361, D361, SR721W, SP361, V361, 362, D362, SR721SW, SP362, V362, 364, D364, SR621W, SP364, V364, 362, D362, SR721SW, SP362, V362, 365, SR1116W, 366, D366, SR1116SW, V366, 370, D370, SR920W, SP370, V370, 371, D371, SR920SW, SP371, V371, 372, SR916W, SP372, 373, D373, SR916SW, SP373, V373, 376, SR626W, SP376, 377, D377, SR626SW, SP377, V377, 379, D379, SR521SW, SP379, V379, 381, D381, SR1120SW, V381, 384, D384, SR41SW, SP384, V384, 386, D386, SR43W, SP386, V386, 387, D387, V387, 388, D388, V388, 389, D389, SR1130W, SP389, V389, 390, D390, SR1130SW, WS-10, V390, 391, D391, SR1120W, SP391, V391, 392, D392, SR41W, SP392, V392, 393, D393, SR754W, SP393, V393, 394, D394, SR936SW, V394, 395, D395, SR927SW, SP395, V395, 396, D396, SR726W, SP396, V396, 397, D397, SR726SW, SP397, V397, 399, D399, SR927W, SP399, and V399.
All Batteries listed are Battery Chemical System “Silver-Oxide” except for these few Batteries Listed: (313, 323, 325, 343, 354, 387, & 388) Those Batteries are actually Mercury Batteries!
Watch Tool Kit
And while you’re at it, Purchase a Watch Tool Kit so you can pop the case back off your Watch, change the Battery, and adjust any links. It works like a charm!

Lithium Watch Batteries are a little more odd!
Lithium Batteries are Flat, Thin Batteries that resemble Nickels! (See Picture)
Lithiums are commonly used for Calculators, Remote Control Car Starters and of course Watches. Watches that use Lithium Batteries are normally the ones that have lots of functions and dials and buttons on them. Functions that use up a lot of juice!
They Cost More!
The sad thing about Lithium Watch Batteries is that Lithium Cells are normally more expensive than Silver-Oxide or Mercury Batteries are. And Some Watches even use 2 of these! Just check out any Casio Watch with an LCD Screen and Stop Watch, it drains a lot of Cells quickly!
Check out the great deals on Lithium Batteries here!
So here you go, the Watch Battery Conversion Chart for Lithium Batteries…
Lithium Battery Chart
This Lithium Battery Conversion Chart Converts Cells for Everready, Energizer, Duracell, Maxell, Panasonic, and Varta. They are all 3.0 Voltage, and Coverts these Battery Cell Numbers: CR1025, ECR1216, CR1216, ECR1220, DL1220, CR1220, ECR1225, ECR1616, CR1616, ECR1620, DL1620, CR1620, ECR2012, CR2012, ECR2016, DL2016, CR2016, ECR2025, DL2025, CR2025, ECR2032, DL2032, CR2032, ECR2320, CR2320, ECR2430, DL2430, and CR2430.
CR1025 is made by Panosonic and goes by a couple of different names: BR1025, P031 ND, and P031 and has no conversion that I know of!
Now some Watch Batteries are interchangeable. Like Watch Batteries 376 & 377 . If your Watch takes either of these Cells, you can use 376 or 377 in your Watch. It doesn’t matter. Either one will work. (Good to know if the store is out of one number and not the other!) Same with numbers 396 & 397! Those can be swapped out! 361 & 362 will work for each other. As well as 395 & 399! And 386 & 301. Companies like Energizer will state right on the packaging what numbers it will work for. (See picture! 357 & 303 are the same!)
Are you Backwards?
Speaking of Batteries… I Don’t know if you know it, but if you put a Battery in backwards in your Watch, it’s very possible that the Battery will leak, explode and ruin your watch! Be careful! Oh, and do keep Batteries away from kids, (especially the Lithium ones) they can block the airways and that’s not a good thing!
So there you go… The most popular Brands, Types, Sizes, Numbers and Battery Conversions!
Hopefully it will help you get the proper Battery for your Watch. If not, have a Jeweler do it for you. I always advise that anyway. People have a tendancy of breaking their Watch if they don’t know what they’re doing. It’s not worth the trouble.
Just take it to a Jeweler and let them change it for you. They have all the tools, and it’ll only take them a couple of minutes.
Buy your Watch Batteries from Amazon and Save money! :)
Pick up a Watch Tool Kit as well! :)
… It makes changing batteries SO EASY! :)
