What does your diagnostic tool say?

Tacking on this thread my question as it is battery related. Anyway, I got ISTA running on my laptop and connected it to my car. During the connection process, I got a message stating that the battery voltage is below the threshold. Reading the battery charge history, it looks like the battery only charges to about 80%. I normally drive 40minutes each way for work so I think it should be enough time to charge the battery. The battery is the original one which would make it about 5 years old. Is it time for me to change the battery?

The battery normally charges to between 80 and 90%, which extends battery life. Check the voltage after the car has sat overnight. If it's over 12v you should be good.

Do I look at my current battery and just buy the same thing?

Also, can either Bimmercode or Bimmerlink help me code the battery? What is the difference between the two?

Since I didn't use my car for a long time during the pandemic, my car was out of battery, too. But somehow I knew the battery could be resurrected. Instead of paying ₺2400 for battery + ₺300 service fees at the BMW service, I paid only ₺100 to my fellow of battery master and had the 12V 90 Ah Varta battery charged like new. It's working like a charm right now.

Ok so I am going to ask an ignorant question…..(2015-F33)
-bought OEM battery b/c I get parts discounts due to my job
-I have a SnapOn scan tool that has a section to register the battery
-We are headed to the Mouse House (hours away) this weekend and I need to put the battery in tomorrow to be safe.

What are the issues or malfunctions if I can’t get it registered by some dumb mishap?
We also have an Airpro scanner which links up remotely using BMW OEM scan tools from a remote location and trained programmers as a last ditch

The car increases the level of charge as the battery gets older, to compensate for its reduced ability to hold charge. If you don't tell the car that you have a new battery by registering it the car will continue to charge it as if it was old, reducing the life of the new battery.

Thank you, what a pain in the buttocks on a convertible....now to register

Hi - I'm looking to replace the OEM car battery on my 2015 335D
The Original BM battery is 90Ah and 900CCA - the closest equivalent I can find is the Bosch AGM 019 Car Battery - S5 A13, or the EXIDE EK950 019AGM, both of which are 95AH but only 850CCA. Will the 850CCA be sufficient for a 335D - anyone replaced their OEM with a different car battery ?

Comments/advice appreciated as both of these are approx £100 cheaper than OEM BMW batter at £233 and that's before fitting - which I'm looking to do myself.

1. Don't post the same question in more than one forum section.
2. Don't ask a question unrelated to the thread title. Start a new thread.
3. Don't post the same question in the same thread a half hour later.

Hey guys, so my CEL came on a few days ago. I don't have a scanner tool but started looking into getting one the next day. It's been on a few days now as I haven't been driving much but yesterday on the way home I finally got a low battery warning on the screen come up. My car is a 2013 f30 and its the original battery. I've heard about coding or registering a battery my question is if I install a new battery without registering it, it will still start correct? I don't see how the car would 'know' I have a new battery installed? The charging makes sense, I just wanted to check and make sure. Someone on here said most auto parts stores will register the battery for you or have a scanner tool a guy could borrow? Thanks!

Before fixing something make sure it's broken. Scan first to find out what that may be. Even if it is a low charge warning that doesn't necessarily mean that the battery needs replacing. It could be a parasitic drain issue.
Scan tools are not optional, they're a must have.

The vehicle will start but the alternator will overcharge the battery until it's registered.
