Can I replace CR2430 with…

Cells that fit the same space but differ in chemistry or voltage.

Lithium, 24.5 × 5 mm. Different footprint — check the compartment before buying.

Lithium, 20 × 3.2 mm. Different footprint — check the compartment before buying.

Check before you swap. Batteries with similar dimensions are not always interchangeable with the CR2430. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.

CR2430 questions

What batteries are equivalent to the CR2430?

The CR2430 is sold as DL2430, BR2430. All of these describe the same 24.5 × 3 mm lithium cell at 3 V.

Can I use a CR2450 instead of a CR2430?

In many low-drain devices, yes — the sizes match. Check the voltage and chemistry against your device's requirement first, because a small voltage difference can matter in calibrated equipment.

How long does a CR2430 last?

A CR2430 holds a typical 270–300 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.

Is the CR2430 rechargeable?

No. The CR2430 is a single-use cell and should not be recharged.
