Quick start
Just enter the number from your old battery, and we’ll instantly show you all compatible options available on Amazon.com. Every battery shown on the Amazon landing page is guaranteed to fit.
Or scroll down to search manually for compatible batteries.
Just type the number printed on your old button cell battery — like CR2032 or LR44 — into the search bar above. We'll instantly show you the matching battery. If it has other names, we’ll show those too. Click the orange button and you’ll be taken to Amazon with a smart search that includes both the battery and its compatible types.
No battery number? No problem. Just measure the diameter (the width) and height (the thickness) of your old battery using a caliper or a ruler. Enter those values into the filters below, and the list will update automatically. You can combine filters however you like — diameter and voltage, or just brand and chemistry — everything works together.
