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.
