Mine did the same n i took a brass bore brush n cleaned the contacts on the collar n charger. Corrosion can cause it not to make a good contact. Another collar did it n it was the connection inside the battery housing that was broke n only 1 leg was making contact. I put it together best i could n dabbed a tiny spec of super glus on the 2 terminal halves n its workn good so far
