Query: Non-stop beeping

This product was used a time of day clock only. It worked for maybe a year. Non-stop beeping started. It kept beeping and displaying "L00". No button pushing could make it stop. I yanked the battery, it kept on beeping. The manufacturer: MacGregor is nowhere to be found. I'm going to have to trash the clock and dispose of the lead/acid battery.
