@davidherna88348 that will be a common CR1220W 3V Lithium battery. You can get one [https://www.jameco.com/z/CR1220-WIRE-LEADS-3V-CR1220-Lithium-Coin-Cell-Battery-with-Leads_2210010.html|like this] and splice the wire to maintain your connector. Of course, you can also look at places [https://www.computer-world.pro/cr1220w-asus-ux303l-p-89170.html|like this] and even Amazon sells them for a small fortune. So, always be aware that you can get poked in the eye :-) The only thing that matters for this battery is that it is a CR1220, because that is the physical size and that it has 3V. Stay frugal and save your money.
