12 Volt A27 disposable battery Pro Tips:
Check your device manual: Always use the specified battery type.
Avoid mixing: Never combine old/new batteries or different types.
Storage: Keep in a cool, dry place to prevent leakage.
In short: If your device requires a 23A, the larger-diameter 27A won’t fit.
Conversely, a 23A will be too loose in a 27A compartment.
Choose based on your device’s specifications!
