Ok boys, now what? I got a new battery a couple days ago, but just now got a notification (I have the HUM thing by Verizon plugged in) that there is a "rapid decline in battery voltage", the exact same thing that happened before when the battery was dead and would not start.
Never heard of it but why didn't it give you a warning before?
And google returns ton of results that HUM is possibly the problem. You didn't think to tell us of that before? lol
If your Verizon hum causing car problems, you must be frustated! Here in this guide, learn the reasons behind the issue & also how to solve the problem.
Does Hum drain my car battery when the engine is off?
When your car is off, the Hum OBD (On-Board Diagnostics) Reader goes into a low power mode.
maybe its defective
"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."
"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"
It did give several warnings before, and almost every time the battery was dead, especially if we didn't try to start it until a few hours after getting the warning.
Anyway, so last night my daughter drives the car to work, new battery and all. She parks at 9:30pm. At 2:30 in the morning I got an alert of "rapid drop in battery voltage". Same warning the other times when the battery was dead.
I checked the app, it shows 11.36 volts.
Now, fortunately she just texted me and said the car started. Also, usually when this happens I will get another notification that the battery is back to full health.
So, what on earth is causing a brand new battery to have a "rapid decline" in 5 hours when there are no lights on or anything obvious that is drawing power?
I'm really not thinking it's a defective HUM considering the times it has sent me an alert it was accurate considering the battery was totally dead almost every time, and the other times the car was started before more time passed.
