One of my engines was slow cranking (diesel 3126 - two batteries for each engine). I disconnected the batteries, and checked each individual cell in each battery using a hydrometer.
I only found one bad cell out of all of my batteries. I only replaced that one battery, and left the others in the boat.
Is this a bad idea? I have heard that you should replace all batteries in a bank, but is that am I just wasting money if the cells check out good with a hydrometer? Should I replace the other battery in that bank?
