That's the plan...if I can ever find the time to get over there and take a look. So..what's the best way to test the cells? Pop the cover off and use a multimeter?
Yes, but I've not looked into the circuit design to know whether you'd need to disconnect any buss bars between cells to get accurate readings. I'm guessing that isn't required since TechStream can read the cell voltages, but that info is being fed through ECU and it wouldn't be powered up in this case. I would probably first try reading V across the plug to test the whole thing at once (assuming your DMM is capable of reading up to 300 VDC), but I don't know what the pinout is.
how much is the battery pack? if it really is an extremely good deal.. you could buy it.. save it for when your current pack has one or two dead modules, replace those, and sell your pack, then order a greenbean battery with lifetime warranty and use the dead junkyard core as the trade in for green bean.. if it's really dead.. if it's good, then sell it and profit.. mean while learning to fix it without any down time of your current car?
65,000 miles a little high....Really, my 2015 Prius C 2 has 106,000 miles and when I checked my batteries in early spring, they were still at 85% capacity (which is really good).... to the original OP...depends on how the batteries was stored after being pulled....Heat is the killer of batteries and heat does lower the life expectancy of batteries.
Well if you were selling your battery, then it would make sense for someone to snatch it up quickly. It would depend on your driving style/conditions I suspect. Not all 106,000 mi batteries are in the same great condition as yours, and we just don't know what condition this one is in exactly....
True, the majority of my driving is superslab...76 miles roundtrip and 60 being superslab-the other 16 are county highways/roads....a few dozen trips from Indiana to Florida in the past 6 years....I really dont do much stop/go city driving...summers, the highs are mid 90s F and winters may get down to around 0'F (no heated/air conditioned garage-stays in the barn at home).
Battery technology is improving and prices are coming down.. so it makes sense to wait until you need it to buy it.
