Uh oh, I've patched a RFT and I don't change my oil every 2500 miles. Here's the end of me, I replaced a lead acid battery in my E60 over 2 years ago and I did not register the battery. I even bought the battery from Autozone without a BMW sticker on it!!!!

With that being said, anyone know what size AGM battery is on the X5? Places to get an AGM at a decent price?

The last time I brought this up was in March when it was 0 degrees in my garage so I had no inclination to look at the battery. In July, it's now 100 degrees with high humidtiy.....I just can't win. I either need to man up or go to the dealer.....
