I was able to take care of the battery install without 19 to 23 (no damage to any of the parts nor didn't I need to disconnect HD wire), however after replacing the battery I am at the same place where I was when I started this replacement. Appears my issue was not a bad battery in a firs place. Device is constantly displaying "Charging. Please Wait..." with explanation yellow triangle and battery and the red bottom graphic. Anyone has any idea what the issue is, drop a comment.
