Replacement 9 Volt Rechargeable Battery
When to buy
- If there is no visual display and the unit is switched on and does not appear to be charging, it is likely the battery requires replacing.
- The counter continuously beeps and eventually turns off, this is normally due to a low battery. The counter requires a given level of power to operate correctly. If the battery doesn't have sufficient power it may continuously beep to warn you. If you turn the counter off for a few minutes it may recover slightly but the problem will not go away, a replacement battery is required.
