trying to figure out besides being a sealed battery without liquid acid, what other benefits AGM brings, longer logetivity? Or what if anything does Lead batteries have any edge on AGM? Battery savvy here we go
Cmon it's got nothing to do with the previous posting I did, I'm curious about difference of these 2 types of batteries, I'd like to put my recent experience between the 2, and pls chime in.oh geeze, go search this topic, save us the arguments again!
long sotry short, go with what the car requires, charging issues with AGM and so on and so forth. read into it. variable charging, sinwave alternator outputs, proper charging, proper ventilation, there are a LONG LIST of reasons why not to and why you should.
just go with a quality battery that your car calls for. nothing else.
btw only 3 companies make batteries, ALL batteries are just off branded versions of these 3 brands.
DON'T BE FOOLED.

Yes I had one of those in my caddy way back in the days and now that you reminded me, it lasted like 7.5 years I gave it for an exchange for a reconditioned lead battery, and the culprit turned out to be the starter, so who knows how long that battery would've lastedthe yellow top optima in my tdi tacoma is over nine years old...ran it dead several times leaving the lights on with no sign of stopping.
I would agree, but I'd be careful not to lump all of the various battery chemistries in together. Obviously none of the Mars rovers have lead acid batteries. A buddy recently built an RV from an enclosed aluminum trailer with three solar panels on the roof. He was going to put in a gazillion pound FLA battery bank, but I told him about cheap, lightly used LiFePO batteries from medical devices (ventilators and such). Saved him a ton of weight on a trailer that was already just about maxed out.FLA GC2 batteries are used in golf carts without any suspension at all.. I'm sure they see significantly more vibration than the battery in your german car.
I actually don't think golf carts are very abusive to batteries as far as vibrations go. They also have deep cycle batteries with thick, robust lead plates. My tractor however sees real, sustained vibrations when it's working, and it's heavy duty lead-calcium FLA battery has held up exceedingly well.
Battery life all comes down to TLC, if you very carefully care for a battery and coddle it like your first born you can get em to go decades.. the mars rovers are proof of that.. but we're not driving mars rovers, our vehicle's are not coddling batteries it only uses for half a second to start. Your car is rather apathetic to your starter battery, its not charging it when its parked, or compensating charge voltage for battery temp, or maintaining environmental parameters to maximize battery life .. so buy the best quality you can get for the least cost, and thats almost always some form of East Penn/Deka FLA rebrand.
I call BS on Florida. Heat is what kills batteries. Most customers in SoFLo are getting 18mo to 2 years.Battery life is more dependent on where you live and conditions you drive in than the differences between AGM v FLA.. A person who lives in Florida, daily drives it and never does a cold start can often get 10y outta a Starter battery.. but take that same person, and same car, with same batteries to a less mild climate and getting 5y out of it could be a good job.
I used to get 6-7 years out of my batteries when I lived in the midwest, now I live in Colorado and its been 4 winters before a new battery.. Of the half a dozen cars I've had here in Colorado, not one of em had a battery last more than 4 winters.. AGM or FLA didnt matter.
When the battery in my Audi TDI went out, there was a ton of things that started acting wonkey.. the rear lift gate stopped closing, the infotainment system started cold booting, blind spot monitoring turned its self off, etc.. however it was still starting and going fine for at least a month with all those quirks before it finally refused to start.. put in an identical battery to the one I removed and suddenly all those grimlens vanished.. When you got a battery going out it acts as a big current sink and robbs other electronics of proper voltage, thats all that you had going on with your old dying battery.. probably had a bad cell internally and would never take a full charge, but could still start the car.
300 seems extreem seeing as coolant temp and engine temps wont really reach higher than 200ish with heat from the sun. 300f would definatly kill any battery, especially lead based ones.Heat kills lead acid batteries. Everybody knows that. I remember visiting my grandparents every winter in S. Florida- when opening the doors to my grandfather's Lincolns and Cadillacs the interior temp would be around 300°, lol. Sitting baking in the sun all day long is brutal on batteries. If you have a climate controlled garage, then it won't be so bad.
I don't know if it's crappy quality (VW penny pinching is showing in a lot of things) or the battery is just not suited well enough for the start stop and the new generator load biasing. I think a proper deep cycle/starter battery would have fared better.What is the deal with those EFBs anyway jason, noticed across the board they've been failing really quickly on everything from the atlas to golf Rs? High electric loads and tight engine bays seem to be the common denominator from what I take it
