I typically buy the 'best' battery. I found it confusing the AGM is the highest price, but has a 3 year warrenty compared to the conventional wet battery, which has a 4 year warranty. My last wet battery lasted 6 years, so this time I am trying a AGM, which are 'supposed to' last longer. I also do not fit OEM size batteries. I fit the largest battery that will fit the tray. Porsche fits a group 47 as OE, but the tray has the correct hold down for a 48. So, I fit the 48, which is about the same dimensions as a H7. My disappointment with this battery is that it didn't come with a hose kit. My hose fit, but I had to pry out the plug for the other side. If you buy this battery, don't forget to stick a plug in the other side that doesn't have the hose. I think the vendor should supply a hose kit, When I bought my wet battery 6 year ago, they did. now they don't. Just beware.

2 yrs ago bought this battery for my 2017 Honda pilot went bad the 1st yr. Got it replaced and within the next yr it goes bad. Took it back and got a new replacement and was told that if this one goes bad in this next yr that'll I'll have to buy a new one because I got my 3 yrs although it took 3, 3 yr batteries to get 3 yrs out of it. Come on, a 3 yr battery should last 3 yrs, not make you have to lose time going back and forth to be replaced and on my replacement receipt it says my warranty begins 3-4-22 and ends 3-4-2025 but the guy said that wasn't the case that the began from my original purchase. Well I got a receipt that say different and if it goes bad in a yr I will file small claims suit to get my money back because as I said, my receipt say my warranty ends on 3-4-2025. I wouldn't recommend this piece of junk of a battery to my worse enemy !!! 😡
