Equivalent batteries
These codes describe the same physical cell as the CR2.
Can I replace CR2 with…
Cells that fit the same space but differ in chemistry or voltage.
Lithium, 17 × 34.5 mm. Different footprint — check the compartment before buying.
Check before you swap. Batteries with similar dimensions are not always interchangeable with the CR2. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
CR2 questions
What batteries are equivalent to the CR2?
The CR2 is sold as CR15H270, DLCR2. All of these describe the same 15.6 × 27 mm lithium cell at 3 V.
Can I use a CR123A instead of a CR2?
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 CR2 last?
A CR2 holds a typical 750–850 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.
Is the CR2 rechargeable?
No. The CR2 is a single-use cell and should not be recharged.
