Terlalu banyak kereta nampak. Yes it's definitely recommended as you can use it on your other batteries too. The real question is, will you be hardworking enough to use it after getting it OR will it sit hidden in some drawer later on ? I have an existing client just like in your situation, too much cars and has an external charger too. One day he pulled it out and ask me how to use it ?

FYI the AGM battery may still be in good condition but there could be other problems that are preventing your vehicle from cranking too.

What is your vehicle make & model bro ?

I tried looking for your model but it's not in our listing. Upon checking further, is it correct that for your vehicle battery replacement to be completed, the battery needs to be registered into your BMW BMS ? Since that is the case I am not sure if Amaron even has the battery code on the battery to complete your battery registration.

Would you know what is the dead battery brand in your vehicle at the moment ?

I do not know what Mixtech battery is that, but what you really require is a BMW battery that has specific battery codes on it which will be required to complete the battery replacement process properly. Installing an incorrect battery without the proper codes to complete the battery registration into BMW BMS will damage the battery prematurely.

I believe the codes refers to the specific number beside the QR code in picture.
