My 2 6V Optimas were not a matched pair but the new ones will be. Size was important to replace the original battery and to give the option of 6 or 12 volts. I have had good luck with the 12V Optimas in my '39 Ford and '64 Chevy pickup, both are much older than the 2 6Vs. I think the age and outside temperature with the engine heat and the placement of the batteries finally got to these batteries. I'm going to try a heat shield with the new ones.

With all the tools I have, I can't believe I didn't own a battery load tester. In addition to load testing the condition of the battery, it can be used to determine an estimate of cold cranking amps, read the voltage and determine alternator/generator output. Handy with a price of only $20 to $40.
