These codes describe the same physical cell as the A27.
Can I replace A27 with…
Cells that fit the same space but differ in chemistry or voltage.
Alkaline, 10.3 × 28.5 mm. Different footprint — check the compartment before buying.
Check before you swap. Batteries with similar dimensions are not always interchangeable with the A27. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
A27 questions
What batteries are equivalent to the A27?
The A27 is sold as 27A, MN27, V27A. All of these describe the same 8 × 28.2 mm alkaline cell at 12 V.
Can I use a A23 instead of a A27?
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 A27 last?
A A27 holds a typical 18–22 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.
Is the A27 rechargeable?
No. The A27 is a single-use cell and should not be recharged.
