I got the regular ZeroLemon battery (not the extended life one) for my LG Optimus G Pro E985 and on its first week it was working fine but lately my phone's been showing me the invalid battery message after fully charging and turning the phone off and turning it on again. Removing the ZeroLemon battery, putting it back in and turning the phone on doesn't seem to work as after about 10 seconds or so, the phone will show the annoying invalid battery message again and the phone shuts down on its own shortly after. So what I did was put in my old battery, turn the phone on and leave the old battery in for like a minute, then turn it off, replace it with the ZeroLemon battery, then turn it on again and that seems to solve the problem. However, I realized that I have to do this whole ritual every time I charge my ZeroLemon battery and it can be quite a pain. IDK of any other alternative to get rid of the invalid battery message and it sucks BIG TIME :'(
