Best place to hook up a battery charger

With the IBS in mind where is the best place to hook up the CTEK battery charger?

The shop manual states "to prevent the intelligent battery sensor from malfunctioning, use the charging points in the engine compartment."

I have a 4 year old battery that I want to replace. It works fine except when I try to listen to the radio (play with the options) for 1-2 minutes with the car off, at that point the battery light comes on. I have the upgraded ~16 speaker package so I assume the battery draw is high. Wonder if a new battery would buy a few extra minutes or if the CTEK charger will allow me to listen to the radio indefinitely with the car off if i'm hanging out in the garage.

I guess I should just read the manual and take it to BMW for every service too.

There are reasons to let the Intelligent Battery Sensor see every Coulomb through it, charge and discharge, and their rate. The IBS is first a Coulomb counter reporting to the ECU. Coulomb rate in seconds is amperes.

There are two charging points under the hood. Positive has a red plastic cover, negative is nearby.

They are on the driver side of the engine compartment.

You have a sum total of NINE posts on Bimmerfest... Some of them (most of them) Utterly newb posts.

Yet you decide to wisemouth someone with 5000+ posts who is usually, if not always. On point with technical advice.

And in fact, in this case- as you can see by all the other people saying the same- he was spot on with his advice.

Do you understand the unique maintenance issues around the E70 V8s, battery wear and the CCP recall? You should.

I think it is pointless. I have a feeling this was wishful thinking post and attempt that there is someone in the crowd to confirm that wishful thinking.

OP - This is a tough crowd but if you can look past that, the wealth and depth of knowledge here is akin to what you can expect in a Land Cruiser forum.

It is a tough crowd. I guess I'll just connect the battery charger to the engine bay terminals from time to time.

I used to work on my e46 back in the day when I had more time. Now I don't so I purchased the X5 with a Carmax warranty because I knew the v8's or just the x5's in general could have a number of big ticket repairs based on the forums. Some of the mentioned repairs are beyond my abilities. I don't have a lift for example so i can't drop the transmission to replace the rear seals.

I could care less regarding the issues with the v8, battery draw, or customer care package. I just drive it into the BMW dealer and they fix it with much cost or any to me. I've already had the rear and oil pan seal, turbos, and various suspension components replaced. I'll enjoy a perfectly sorted car for years to come without worrying about expensive repairs and will sell it one day in a perfectly mint mechanical condition before the warranty runs out.

So far my warranty has paid off just getting the car sorted. Yes it was a lot. I can always get my money back based a prorating(mileage/time) if i decide to cancel it or I could even transfer it when I sell the care.

Should I have bought a newer car without a warranty, maybe. I wanted to try something different this time around and hope it works out.
