Life Expectancy of OEM 12 Volt vs Optima(LearningAid)

[dorf]

I've read the prior posts on the 12 volt life expectancy but nothing posted on the Optima life expectancy.

I'm used to purchasing a 60 month battery and then just replacing it in about 36 months.

That seems to provide a measure of safety,of not getting stranded with a inop battery.

I'm assuming that the OEM 12 volt should be reliable for about 36 months and the Optima should last longer, but the Optima web site claims free replacement for 36 months nothing further ????


Anybody have actual and factual comments to share ???

Over last weekend my dome light got left on [cause uncertain,
not going to point fingers] bringing my Yellowtop down to about
7V for the first deep-drain since I installed it. I hooked up my
small UPS to the parallel Anderson connector to boot the car.
After having the system powered up for a while the battery seems to
have bounced right back; no perceptible diminished IG-ON voltage or
capability seen so far. And I'm pretty aware of subtle changes
in these areas...
