I just picked up this code scanner. It had an option to reset the battery monitor. I used it when I replaced the battery in my car. I believe it worked.
I only had the radio turn off once after a few minutes. Haven't tried for any length of time but I haven't noticed any issues. Battery the first day seemed to be charging normally. The old battery was consistent at 14.6-7 volts, the new one was more variable, but that makes sense to me. Will have to check it again.
