I had not ran or operated on my layout for 3 years and 9 months! Right before I tore up a bunch of track back then and used my new Railpro at the time. Probably about 3 or 4 times. Anyway my problem is as soon as I run a train within 10 minutes the HC-1 shows about 50-60% charge already. It goes down from there, but not as fast. I'm only running 1 train for about 12 scale miles while doing laps. Also, do switching and it goes down in the same manner. Is it a bad battery or is a reset in store? It did run down fully 1 or 2 times over the those 3 years 9 months. Always charged right back up. but I wasn't using it. Thanks!
