Where is the battery in a 95 749il?

[chapstick]

Who knows where the battery is for a 95 740il?? During a snow storm, I couldn't pull my car out for a couple months, I tried to start it this morning and didnt start. I was able to get a jump.. But it wouldnt start back up .. Is this something i can do myself or do i need to take it to the dealer ?

Don't know about US editions, but in the European E38 models the battery is always in the trunk, below the right cover near the tail-light.

In the motor-compartment (on top of the right-front part of the engine) there's a positive battery-pole (underneath a plastic-cap). A negative pole can be found just to the right, on top of the chassis-suspensionmounting. Connect both to a (powerful!) battery and jump-start. Must work.

On the 88-93's, I believe you had the optional battery in the trunk, meaning that if you had this optional battery, you had two batteries. E38 Euro spec's might have been different in this respect. It would be interesting to know if you have a battery under your rear seat as well. That would be the main battery if you did. The main battery for the E32 was under the right rear seat, with an optional battery in the trunk, usually used for the optional phone and a select few other accessories.

The battery pole is on the left side of my E32, and it is a left hand drive Jap spec, imported to Canada about a year ago. I might be different for the Euro spec/right hand drive E32/E38's.

E38 740i and il batteries are in the trunk. Right side behind fold down trim panel. E32 and E34 are under the rear seat. E38 750il has 2 batteries. Both in the trunk. Even the protection models. I can't believe some of the ridiculous answers I've been reading to some of these posts. lol

Well, then BAVARIANM, share with us your insites and almighty wisdom about the 7-series BMW's! We're doing our best with the people we have on hand.

I, for one, am more familiar with the E32's. I have found that some things on the E38 are similar to the E32's and I help where I can and learn new stuff along the way. I'll admit, I don't know much about the E38's.

Sometimes people will post for help and NO ONE will respond for days. Take a look at the other post you replied on. The first post was made almost a month before. Perhaps you are just what this forum needs, but don't let that go to your head. We're all here to contribute, some know more about our beloved 7's and others ask a lot of questions. I'd never let any BMW Master tech touch my seven cuz one told me once that he and his mechanics would rather take a beating than work on a 7-series BMW. How can that master tech call himself a master tech if he's only good for working on 3- and 5-series? Not that I had planned on letting any Mechanic other than myself work on my car. It's not that hard in reality. (And in no way am I insinuating this of you)

I'm just trying to help where I can. I appologize if my answers have been ridiculous at best and have failed to reach a certain level of knowledge as a result. But I, for one, will be more than happy to hear where my comments have been 'ridiculous' and I welcome any correction you can provide, oh great one!

I don't know anything about the E32, but on most E38's there's just one (large) main battery in the trunk. In my car (with extra alarm/security package) there's a small back-up battery for the computer backup, alarm-system and siren and localizing device, but it can't be used for i.e. starting, lights, etc (seperate wiring).

As far as I know, the regular E38 does not have this 2nd battery. Only if an extensive alarm-system is present. The back-up battery is stashed away somewhere underneath the car, along with the alarmsiren, well hidden behind the right exhaust and heat-covers. Totally unreachable whithout trashing the entire car first

Good to know...thanks for this, DutchDaniel! If you want to know a little something about the E32's, the main battery is located underneath the right rear seat. It's a bit of a pain in the butt to get the seat out and back in again, but one get's proficient in the art of E32 rear seat removal. The optional battery was in the trunk. Not too sure where they put it in the trunk, as I know the car never had the option installed, but it was in the trunk...

Having the battery so close to the trunk, or in the trunk if you have the optional battery, make for a very breezy install of an aftermarket amplifier, as the only wall you need to go through is the trunk, at most. I have been thinking about installing a second set of positive and negative battery terminals in the trunk in case I need to jump start my car, I don't have to do the emergency unlock procedure to open the hood to get at the 'remote battery terminal' under the hood, which as you know, all the locks are powered, except the trunk....anyways, you probably get the picture.

My E38 has exactly the opposite: The trunk-opener is electronic, also closes electronic (can be done by remote on the key). The hood-opener however is mechanical (pulling a wire) and therefore the second set of battery poles are reacheable under the hood.

[lincolnmaster80]

The hood on the E32 is mechanical as well...but getting to the release in the car with a dead battery is next to impossible with powered locks. There is procedure you can do by taking the left kidney grill off to access the cable and open the hood...just hope that the OBC alarm isn't coded else the alarm will sound while you're doing this and get's annoying after the first few moments.

Here are some other ways people have come up with to open the hood remotely:

The emergency/manual unlock procedure involves one of the front doors...don't know which one cuz I've never had to do it. Basically, you put your key in, turn it while lifting the door handle, and you'll feel a little knotch in the handle. Then turn the key some more and the door pin can be unlocked manually. This will not work if the car is deadlocked or doublelocked. The only problem is, you have to re-sync the door locks, else that door will not lock with the rest of them. To do that, you basically lock it in the same manner you unlocked it.
