About the question. No one here will tell you to go ahead. The liability is far too much for anyone to say yes.
I have a Acer aspire 5742z and the battery is faulty.
The original battery is a AS10D73 11.1V 4400MaH/48Wh. Looking to buy a replacement and found many alternatives (see links below) but the voltage is lower........ 10.8v. Is it safe to buy and use? It says the battery is compatible with my laptop model.
Any advice would be greatly welcomed.
