I bought a charger that will wake up a Lithium battery and charge them. Its from CTEK. It has 7 LEDs - it got to the test LED and then started blinking on mine (basically says that the battery won't take a charge).

At this point, I'm really trying to figure out alternatives. Our battery stock says

770A
69AH
860 CCA

Now my question is - how does one read these specs. Maybe I'm cynical but I really wonder about the 69AH.

Options: Braille i48CX - as noted -
25 AH
but, right below that it says 75 LAH (Lithium Equivalent to Lead Acid Amp Hours). So I'm wondering if stock quote of 69AH is actually LAH

Another option: AntiGravity group 48

It can be spec'd out with 60AH which seems close. Price is much cheaper than all these alternatives.

On the other hand, this site shows the stock battery at only about $150 more - considering how much these are, maybe its worth just getting that. https://www.bmwpartsdeal.com/parts-l...m/battery.html


Hello , i have just today 23.08 received my charger ,revived my battery using noco 10 genius
i will write a full post soon on how i did it.

I will also write a quick guide here

What i did was dis-asamble battery out of tray and hooked up charger directly to cells bypasing module, after they were charged 14v it still woud not unlock module, so i gave it force charge for 5 mins 20v it unlocked module and battery was saved!

Write me in my DM's i can call you via facetime and explain it to you
