@corklad I think what you are running up against is a battery issue. Amazingly enough we forget that the batteries in our “smart devices” i.e. cellphones etc are also smart batteries. They do more than just provide the needed power. If those batteries are discharged beyond a certain point ( that point on cellphone batteries is around 2.6V) your regular charging circuit does not recognize the battery. The battery then turns into something like a possum and plays dead. Sometimes, and I do not say it is smart or works all the time, you can wake those batteries up. Use a 9V battery and connect that to the positive and negative connection of the cellphone battery for a few minutes. This will “charge “{ the cellphone battery just above that point of not being recognized. Hope this makes sense.
Hi friend,I think you need change the battery.
If it charges battery A but not battery B. Then I think it should be obvious that battery B is at fault.
Yes, a dead unchargable battery .
