I have put my cars on a 33-36 month preemptive replacement schedule (I find they conk out at that time). I have a new to me Highlander that has been parked in a garage (my cars are outside 24/7), and so far, has had 4-5 years on batteries (car has been in the same area as I live in). The three year anniversary of its replacement is Oct 2019. The cheapo in me wants to try to squeeze as many more months out of the battery as I can get. The impatient part of me that hates it when I have to call a tow truck, wants to replace it now.
I called my local WM TLE and I was told that I can bring the car in, and that it would take about an hour or so, but they can test the battery to see how much life is left in it. Is this a reliable test? Is there in fact a reliable test for how much charge is left in the car battery (I'm talking about the 12v, not the hybrid traction).
