After full use of the battery, I am surprised that this one did not recharge the charger (LED charge indicator unlit) ..it seems that connectivity was a failure since it takes at least 5 Million for find the exact point of contact by putting the battery slightly askew so that the charge indicator lights and pray it does not move from this position the time to load ... I asked for a trade and waits response. I hope the seller will be conciliatory because a first battery was sent to me and the package was "lost" ... my bad battery is the 2nd sends me ... they did not bowl for me obviously.
