Hello warp2diesel,
I am 95,000 miles on my original optima battery.
When I load test it with my tester is reads fine. When I take it to the Advance Auto store it says replace.
Every-time I use my boost-box the car fires up fine. It does look like the evidence is pointing to a battery. What is very confusing is that the car may start up with no problems for 5-8 times and then start "clicking" again...
Thanks,
Tom
Is your "tester" a multimeter? I believe, a true, battery tester puts a load on the battery and measures the voltage/current emulating what is needed to engage the starter and provide cold cranking amps (CCA). So, Advance Auto's test and your starting behavior may indeed point to the battery.
Sorry, I didn't see "When I load test it with my tester..." Maybe it could be it can't hold a charge?
