i have a pivot megaraizin installed in my car. i noticed that most of the time it shows two readings. 4.7v and 10.5v if i remember correctly. i understand thru some research that 4.7 is the lowest voltage at the start of engine and 10.5 is the real voltage. my questions is how will i know if this is healthy? how will i know if its time to change the battery or my battery has some problems?

i went thru this but still dont get it...
