If you are going to try to charge/maintain a Porsche OEM battery, also be sure to verify battery "fluid" electrolyte level...... I had not had a battery go low in so many years that I forgot to check. I knew it was getting weak after sitting and I was plugging in the maintainer and/or charger. After I swapped it out, I removed the six little caps.....wow.... look I can see bare plates..... Obviously that's going to kill it real quick.....

I agree with the five year rule -- but extreme climates may require three year replacement intervals. As Bull said, depends on typical useage -- I believe daily driven batteries will last longer, possibly the full five years or beyond.
I had a Mercedes E class that would eat batteries about every two years -- and those are freakin' tractor batteries!!
