measuring the terminal voltage of a battery is NOT a true test of any battery.
Normally you do a 'load test' on a battery to calculate it's 'state of charge'. More testing and friggin math, but if you follow the MFRs proceedures, you'll get close to what they say. With Gate's batteries I was using, I did a 'load test' every 22.5 minutes and had 'alarm' bits sent to the host as 'OK', 1/2, 1/4, 1/8th charge left.
Silly thing with EV batteries... you HAVE to use their energy to warm themselves up before they can be used in Winter(cold days) yet 'they' don't publish how much that costs in fewer miles driven. Same with NOT reporting what happens when you have the heated seats on, defrosters on, heater at max, infoscreen, etc. while stuck in a traffic jam Xmas eve..... Also not posted is what happens when the battery gets real low. In the case of Teslas(1st gen for sure), you can drain the battery down and NOT be able to get into the car after it locks itself. At least Ford has a 'cutoff', where car can't be driven BUT you can still get into the trunk to get the power cable !
