Thanks Lwillis and all for helping me.
Strangest thing, just gone to bed now and volume of beeps back to normal.
Only thing that is different is that I removed battery a second time and cleaned the battery connectors with steels wool as they were a bit black and oily looking
Im going to buy a new battery and if any further probs I will let you know.
Thank you all very much for taking the time to help me. I really appreciate it,
Thanks
Kev
