I have a new joye 510 mega battery that would not charge. I tried it in two different wall chargers and neither would charge it. So I just recharged my old battery with no problem. I contacted the seller who asked if the charger light was blinking. So I put the dead battery on to check that, the battery started blinking red (not the usually blue) and now the charger won't charge my other battery. Could the battery have shorted out the charger?
