Hello I bought a EZ-Flash IV back in March and it worked flawlessly until today. Everytime I start it up now it says "WARNING! Low SRAM Battery!". The SRAM Battery is probobly the internal battery in the cart, though I bought it brand new and heard batteries last years before dying, though mine died already. I guess I need to replace it but what battery do I use? I have a 2015 microSD model of the EZ-FLASH just in case that is important. EDIT: I think I posted it in the wrong place since it is the MicroSD version and not the 3 in 1. Sorry about that.
