AGM or Lead Acid Battery
Hey all,
Car wouldn't start this evening after sitting in the work carpark for ~6hrs. First time it's done this. It wouldn't even begin to crank over however all electronics worked. Jump started it and drove for 2hrs and now it's fine. I'm running on the OEM battery from 2010 so this has lead me to think that the battery may be on its way out.
So my question is (after doing research): [are there any negatives if I replaced the battery with a non-AGM/lead acid battery? Or is it recommended that I stick with AGM (what the OEM battery is)?
Cheers,
Linh

AGM has a different profile on discharge etc but generally better than lead acid.
I have no idea what is in my car. It is stock.
Only reason I know a little bit about AGM is that RVers have gone to them but our charge controllers have to be changed for a different rate and so on.
Some are going to Litthium Ion, which are super expensive but one batter can replace 4 very heavy high capacity lead acid and save a tremendous weight. But one batter of right size is over 4 grand right now.

ok, AGM it is. i couldnt find many ppl on here who have tried lead-cell. most people have recommended to just stay with AGM.
well as of today, the car has started fine and has started a few times just fine throughout the day. not sure what happened yesterday. i'll monitor for now and IF it dies again, i'll definitely replace with an AGM.

Measure the voltage across the terminals in the morning to see how charged it actually is. I would get a trickle charger (which will also show the actual charge level) and get it back to 100%.
I left a load on my battery by accident and drained the thing down to like 7v....completely dead. I put it on a charger/desulfator for a week and it was back to 100%.

lets' say something were to go wrong with the car electronically, and you take it to the dealer, and they see that you have swapped out to a non OE battery, could they deny coverage?
