Hi all, I searched the forums but didn't find anything for this...I have a Hum obdII reader and service from Verizon. It's generation one and I keep getting yellow battery alerts but the voltage isn't actually low. I called Verizon and they told me to have a garage clear the nonexistent low battery code Thai only exists from their unit in their software (facepalm).

Anyway, the actual battery voltage despite it reporting it was under 12 volts was actually 12.94 after sitting all day after the Alert and started just fine. Is anybody else having this problem or even use the dang thing? My in-laws insist we both have one for the accident awareness and safety reasons, but winter's a coming and I don't want to find out this little thing is draining my battery and just hasn't killed it yet.

2016 Honda Fit EX 21k miles. (New battery installed in September)

Thank you all!

So I looked It up and it says it continues to run in low power mode after you turn off the vehicle. I have been googling around the Internet and have found other people with similar type issues except my battery never Goes dead.

It happened again last night, and this morning when I check my battery it was at 12.94 V. I haven’t driven it all day and I just checked it again and it’s at 12.89 V. So even if there is something that is draining the battery, it is minuscule.

I guess other than an annoying false battery alert, this is a non-issue. It’s either a faulty unit that Verizon won’t replace, or there is something strange happening where the battery temporarily dips and then comes back up on its own without being charged...which seems unlikely.

Anyway, pretty lame for my first post :-)
