Battery change, where to vent new battery?
After a few instances where my windows lost their memory recently, I've decided to replace my battery with a new one. I pulled the old one today so I can do a hard reset when I pick up the new one tomorrow and install it. The old one is not vented and I see no obvious place in the trunk to vent the new one outside. What am I not seeing?

One caution for which I can thank my specialist's technician. Many of the long case batteries have two vent ports on each end (You only have to use one.) In many cases they are both open when the battery is purchased and there is a little plastic bag attached to the case with the tube adapters and blanking plug for the unused port. If you have the unused port open, the gas will not vent through the overboard discharge defeating its purpose.

Just as a follow up. When I picked up the Advance Auto brand battery, there were no plugs or "kit" to vent it. They did give me one vent plug off another battery to use on one side, but I'll have to create my own fitting for the vent hose since it was missing on my old battery.

You're right. Out of an abundance of caution, a maker might put a vent on an AGM (maybe the lawyers or marketing guys demanded it; the engineers didn't) but it's really not necessary. AGMs are widely used unvented in confined spaces.

if i might add, the AGM vent where present is not an open atmospheric vent such as with lead-acid cells. it is a high pressure blow-off valve. adding this however ruins the neat aspect of AGM cells where they can be mounted in any position. when this vent is present, it must be on the high side. and no, it does not need an overboard discharge.

I had a failing battery putting out 12.V, as a result I was having numerous electrical issues and car went in failsafe mode (that is the worst position you can find yourself in short of dead on the side of the road). Just installed AutoCraft Platinum AGM Battery, Group Size H8, 850 CCA from Advanced Auto (actually 900 CCA) with a 20% online discount. Car runs perfectly and I removed the codes via my OBD II scanner. I have only had the car for a few weeks but I am learning that there is a wealth of info on this forum and youtube. In addition it is not difficult to do it yourself - tool accessibility is key but that is what Harbor Freight is for. The third key takeaway is find where Jag goes for their OEM - you will save quite a bit. Also the car was built in 2002, engineered/designed in the late 90s, we can improve on this, an AGM battery is just one example.

true to its heritage in many regards a hand designed and extensively hand built car with fit, finish and mechanical tolerances such as ours will never be seen again.
