We recently had a "Battery Life" error message appear on our Brother GT-541 digital screen. After a little research we found out that we had to replace the lithium battery, model CR2032. We needed to disassemble parts of our DTG printer in order to change-out the battery. Some of the instructions we found online didn't cover every step. There wasn't an instructional video online, so we recorded a "how to" guide on replacing the battery and getting your Brother GT-541 back in service. It's nerve wracking to have printing orders due and then have your printer fail. Hopefully this video saves you some time and gets you printing ASAP!
