Is battery load testing a sure way to tell whether or not the batteries in my burb are in need of replacing?
It seems that when it's 32F or colder, my truck is really hard to start because it turns over so slowly. But if it's plugged in, it starts very well. My theory is that the extended glow time needed when it's not plugged in puts more of a load on my batteries, and the voltage doesn't come back up quickly enough between glowing and cranking to turn the motor over fast enough.
I just put in all new 2/0 battery cables. However, this problem existed prior to that.
