Hey Scotti
I have a 2021 Kia Sorento with one of them there AGM Bat-trees. I won't be needing one for a while but when the time comes does a replacement have to be an AGM or can I use a conventional type with the same cold cranking amp rating.
Go ahead tell my wife. I dare you!
The best place to check: your owner's manual.
I have always replaced AGM with AGM. I've upgraded from conventional to AGM when, as @kaizen pointed out, I've added more modifications that require more power.
I've never gone AGM to conventional as it can wreak havoc on your electricals. On most cars, as mentioned above, you also have to swap out the software to make the system identify that AGM is no longer in use. It's just a pain. If you have AGM, just stick with it.
I tend to concur. If a car comes with AGM, best to stick with AGM. The reason car makes go with AGM is because of the added power requirements for many modern cars.
If the car comes with conventional, I believe you can upgrade to AGM. IMHO, it is wasted money, UNLESS you modified your car for more electronics.
if the car comes with agm.. then get agm. I remember prof explained that to me... He said that If car comes with AGM then get AGM to keep it same. If you want to put lead acid instead of AGM, then I believe you need to change software on the charging system to match the battery.
i meant battery voltage and amps.
Most people don't need AGM. They're a waste of money in my opinion. What's wrong with a $100 conventional battery that will go 5-8 years?
AGM vs non-AGM have different charging characteristics / curves. So if you just replace an original AGM with nonAGM, your car wont charge the nonAGM battery correctly. So better just stick to AGM.
