I had purchased the battery 2012 for my elderly MDA Pro. Since the power supply of my tablets had recently given up the ghost and I could not get a replacement at short notice, I was on my MDA Pro 21:12:14 take again substitute in operation. The battery I had, perhaps loaded since buying in 2012 3-4 times. After a short time, the battery trim my MDA Pro raised significantly. Pale with fright, I immediately pulled from the charger cable. But see for yourself - When I solved the battery panel, a picture of the destruction gave me! To appoint third-party batteries from the Far East, is extremely dangerous !!!
