First of all, I love this trimmer. I've had it for probabaly 15 years. The settings are so precise and I'm so used to it that I would hate to replace it. It is a rechargeable model, which plugs into a cord, not a charging stand. The battery hasn't charged in probabaly 10 years. But since it stopped charging, I was able to keep using it by having it plugged in. I was able to do this for a long time until several days ago. When I'd turn it on while plugged into the outlet, the motor would barely even run. So I took it apart, looked around, and figured I would try to replace the rechargeable battery inside. I sourced a battery, installed it, and the trimmer worked again. I charged it overnight and went to use it the next morning. I got about halfway through when it just completely died on me. So I would turn it off for a few minutes, let it maybe charge a little and try to finish my trimming. At this point, I could maybe get 30 seconds of really weak performance before it would grind to a halt. I tried plugging it in and using it that way, as I had done so many times before, but that wouldn't work either. Can anyone advise me as to what's going on here? Why was I able to use it for so many years with the a/c/ cord and a dead battery, but now with a fresh battery, the a/c cord is useless for operation and obviously useless for charging as well? So I'm wondering if there might be a way to convert this trimmer to strictly a/c, remove the battery from the eqation, and operate it that way? I'm no electronics guru, by any means. But If instructed, I'm sure I could get this thing operational again. I don't care about it being battery powered anyway. I use it in the bathroom where there are a couple of very handy outlets. Thanks.
