Query: Waste of money and not even the product advertised.

I order two Powersonic PS-12180NB batteries sold by eComElectronics on Amazon. What they sent me were two ub12180 from another manufacturer (which can be bought cheaper on eBay). The batteries charged and seemed to be working fine but after the first charge neither battery would charge in the device I bought it for nor would they charge out of the device on a battery charger. I notified eComElectronics and they did not respond. Complete waste of money and not even the product advertised.
