Batteries galore

I'm not entirely sure why various battery powered devices all decided it was all change day - but they did, so I sorted out the batteries collection whilst I was at it! I forgot I had some hearing aid batteries. I don't need hearing aids (most of my students are of the firm opinion I hear far too much., far too quickly..) but I had a year where I had several students who did and it was well worth my while keeping a few spare ones in my meds bag along with the spare 2032 batteries I always carry for my blood glucose meter.

I've concluded the new battery in the door bell hasn't helped though... so a whole new one will be acquired in the near future.
