Yup... that pretty much sums it up. Usually its best to updatr the VO first and then do the coding. then check to make sure the setting are set properly. Then last step is to register the battery once you are ready to close up and call it a day.

Below are specs from Group 49 batteries. I selected Group 49 as it is the biggest that will fit in a E9x without modification. You will notice I paired up Lead Acid vs AGM batteries for each brand to be as close of a spec comparison as you will get. Since you probably aren't very observant, I will point some things out for you. When comparing each pair of Group 49 batteries, you will see: - All of the Lead Acid Batteries have a higher cold cranking amps - All of the Lead Acid Batteries have a higher reserve capacity - All of the Lead Acid Batteries weigh less - All of the Lead Acid Batteries are less expensive Napa Legend, Lead Acid, CCA 900, 185RC, 56.5lbs, $139 Napa Legend, AGM, 850CCA, 170RC, 58.5lbs, $179 Super Start Extreme, 900CCA, 185RC, 55lbs, $160 Super Start Platinum, AGM, 850CCA, 170RC, no weight given, $175 Duracell Ultra, Lead Acid, 900CCA, No RC given, 54.5lbs, $151 Duracell Ultra, AGM, 850CCA, No RC given, 57.75lbs, $204 Bosch Premium, Lead Acid, 900CCA, 185RC, 49lbs, $180 Bosch Platinum, AGM, 850CCA, 160RC, 52lbs, $220 Hmmm, odd, that backs up EXACTLY what I originally posted. Imagine that. |

I run an ACR in my Malibu, with one battery running the stereo and the other the rest of the boat. I have a 20amp dual bank on-board charger (setup for AGM and it's a nice charger) and charge it after every outing. Yet I still only get 2-3 years out of the batteries, even with the better than normal care they get (including a maintainer charge from my charger all winter). I have never seen any advantage in my boats or ATV's for AGM's lasting longer than lead acid. As mentioned in my post above, they weigh more and have less capacity. IMO, unless you need a sealed battery, there is no good reason to go with AGM over a Lead Acid. I can't comment on Gel cells as I've never messed with them and Lithium Ion are way too pricey to play with. |

let me clarify..
i took out the old bigger capacity lead acid.. it freakin weighed a ton and was a total bitch to get out.. well i went with a slightly smaller AGM in my car e92 with all options... and its running great... it was lighter and easier to install.. i like it thats my experience...in car... not a boat ... not a plane. the reason i got a Duralast Platinum is because of its 3 yr... new battery replacement... so if it craps out i get a new one.. its also got some good reviews: http://www.bobistheoilguy.com/forums...Number=2897005 so your going to comment on your AGM boating experience? which is a total different application then cars? why you dont you put 2 AGM in your cars like i have and let us know how it goes? a battery thread is like an oil thread... everyone got the personal preference and experience... no need to be rude to one another... i read AGM have better cranking power in the cold?

As for your example, you could have put a smaller lead acid battery in as well. It would have been even lighter and had more output. As for AGM, a lead acid battery has more CCA (Cold Cranking Amps)...that should answer your question. |

I had an NB Miata. Those came from factory with Panasonic AGM batteries. Lasted 10 years for me and could last even longer. Many users reported 10 years or more usage. And this is with a car usually not driven daily and stored for winter, which means battery seeing more deeper discharges. It could be the quality of the Panasonic but I bet it had something to do with it being AGM also.
News and reports I found say BMW has chosen AGM on its cars that has stop-auto start and intelligent alternator control features, due to battery being discharged more often and AGM being more robust in that. |

Old thread revival... Figured I would give an update on my car and the AGM battery.
I am almost at 190k miles and my voltage in the hidden menu still shows about 12.2v I believe the AAP H8 AGM battery went in around Nov 2014 at just under 100k miles. I’ll provide another update if I still have this car in Nov 2021 at the 7 year anniversary. I suspect by then people would be talking about LiFePo4 battery installs? Below is what INPA shows about my battery today: Last edited by fazman; 01-05-2020 at 09:53 PM.. |

Hi Everyone,
My apologies for asking this, but it appears that there's so many conflicting reports. I need to replace the battery on my wife's '08 non idrive 335i that currently has a Bosch S3 lead acid battery. Can I get a brand new generic replacement battery without having to reprogram it or do you have to go with an oem battery to avoid reprogramming it? Again, this is a non idrive 335i. Thank you greatly in advance for the help, input and advice! |

it must be registered to tell the car you've installed a new battery.
it will need coding if it is not the same AH capacity as the original. |

If you can the exact same battery type and specs, you will only need to register it as a new battery. If you change the specs or the type, you will have to program and register. |

Buy the AGM and code it using Carly. I've done it before with Carly. No issues. I bought the AGM battery that Autozone sells for our cars.
In the future, you are way better off with Bimmergeeks app & cable. |

I just replaced my battery 1 month ago (when I bought my used 335i) and was stuck with the same issue about which battery to buy. Showing the same symptoms of some comfort features starting to be turned off. So here are the results of my research and what I did.
I went from Lead acid to AGM. The old owner of my vehicle has never changed the battery (est. 2008). I bought the Oddysey 49-950 (https://odysseybattery.ca/product/49-950/) as it was near the "AH" as the original battery (stock batt: 90 AH Odyssey Batt: 95 AH). Used that link to purchase the battery. I think they are located in Ontario so it voided any custom fees I had to pay. Total cost with shipping was around ($400 CAD). As for the coding. I have researched about methods to code and register the new battery. Came across Carly, because it was easy and convenient. Then I stumbled upon a video that said to never use carly as it doesn't properly change the values in your car. Then I stumbled upon a video that shows how to properly code the change from Lead Acid and AGM and Code it the correct AH capacity using INPA and NCSexpert. So I set up INPA and NCSexpert and did it that way. Car has been with the new battery for about a month now with no issues. (PS: if you want the link to the videos that I used that helped me code and install the new batt, or the video that proves that carly doesnt code the car properly just shoot me a DM) Last edited by tomasp001; 02-18-2020 at 08:47 AM..
