Did you know?: The original 600mA Yale control panel battery must be replaced every 3 years? Depending on your control panel model, it may not inform you of a low battery. To check your battery's life simply disconnect or unplug your control panel from the mains socket. If your battery powers the control panel for less than 30 minutes, the battery should be replaced asap. All batteries are available, please see my other listings for details.
In the even of a power cut, a depleted control panel battery will cause the siren bell box to sound. The Extended Life battery will offer 8 years life before needing to be replaced. If your control panel is beeping, it may be a sign that a new battery is required.
Collection in person is available from Wolverhampton, West Midlands. Please contact us before purchasing for details.
