or more specific alarm key fob battery help My bike came armed with a Datatool alarm - usefull and annoying at the same time Anyways - after nearly a couple of years use the key-fob-thingy needs a new battery. I opened it up and found that it wasn't a nice standard battery that you can get from 't corner shop oh no, it's a 27A 12V super alkaline thingy. (looks like a AAA size but much smaller. I did pop into a bike dealers in Goole when I was passing last year and when they finally found one it was "HOW MUCH !!!" So, anybody on here got any idea where I can get a replacement battery without going into double figures thanks in advance
