Porsche AGM Battery for 2007 997.1 GT3
(CA) | June 22nd, 2016
I already had the original GT3 (Moll 80-Ah, #BATTERY542) battery replaced twice. Not too bad for 9 years. That being said, Moll is a very high maintenance battery. During these 9 years, it's always being hooked up to a Porsche battery maintainer (PBM #95504490054) and I had to check the acid fluid level on a regular basis. It's time to replace the battery again and I got tired with the maintenance so I wanted an AGM. I have checked other brands such as Odyssey, Bosch, Exide and more. Only Banner & Exide offer 80-Ah as required by GT3s. Since SunCoast offers Banner 80-Ah at a great price, I went with this Porsche OEM. SunCoast shipped it fast and well packaged in a box. Installation's a simple DIY and took only 10 min. Like others mentioned, the 'venting hole' was on the other side or on the negative side and the venting tube was too short to reach it. Since AGM batteries are sealed and no venting's required, I did not hook up the venting tube and so far no problem at all. I still hook it up to PBM nightly with no charging or compatibility issues. A fully charged battery is always a happy battery. I highly recommend getting both the Banner VRLA & a PBM from SunCoast as this combo will last this battery for long time.
Porsche AGM Battery for 2003 996 Targa
(Washington, DC) | June 7th, 2016
My last battery was not Porsche original equipment due to the circumstances under which the prior battery failed, and developed a bad cell after a year and a half. I think that it is worth the extra money for the sturdier construction and dry mat technology of the AGM, not to mention the depth of endurance and strong hot start performance. If you have a front strut brace (mine was a Schnell), you will have to remove it to get the AGM seated properly. Also, my battery vent hose is on the positive side of the battery, and the AGM came with a small white plug for the vent hose opening on the positive terminal, so I needed to remove the plug and transfer it to the negative side. Not a big deal, but the plug is almost flush with the battery case and not very large, so you need to take a little care in removal.
It's a battery.

Product worked as described with one exception. On a 2008 987.1 Boxster the Battery vent hose will not reach the vent port. It is on the exact opposite side compared to the stock non-AGM battery. Every battery has of course two ports, but on the AGM Battery it is sealed on the (+) side and open on the (-) side. -- The battery still needs to be vented, regardless of it being AGM or not. Also this AGM battery is a bit heavier than stock. I measured the old battery at 41.6 lbs, the new AGM battery at 51.5 lbs., same 70Ah.
