Edge 130 (original) Battery Life Declining

Hi Folks,

I’ve be using my Edge 130 (not Plus) for about five years.  In the past month, it has quit in the middle of a ride after no more than four hours of use.  When I get home and turn it on, it shows that it still has two bars of battery left.  What can account for this?
