Frequently Asked Questions

Can CR2330 be used in place of CR2032?

No, you cannot use a CR2330 battery in place of a CR2032 battery. Both batteries have the same voltage, but they are not the same in thickness and diameter. A CR2330 is bigger than a CR2032, so it will not fit in the same space. If you try to put a CR2330 where a CR2032 should be, you might break your device or the battery, which can make the battery not work right.

Are CR2330 and CR2032 batteries interchangeable in most devices?

No, CR2330 and CR2032 batteries do not work in most of the same devices. This is because they are not the same size. The size impacts how the batteries fit and work. Each one is made for devices with specific measurements. So, you usually cannot swap them out and use one instead of the other.
