The battery in your BMW E60 is an absorbed glass mat (AGM) type, which is different from the older style lead acid batteries. AGM batteries house the battery acid in glass mats. Lead acid batteries house the fluid between lead plates. AGM batteries are made of very thin glass fibers woven into a mat. This increases the surface area enough to hold sufficient electrolytes on the cells for their lifetime. Where lead may absorb some of the acid, shortening battery life. There are positives and negatives when using AGM over lead acid batteries. For example, an AGM may charge faster, but is more susceptible to damage from over-charging. They produce less gas than a lead acid battery, can be mounted in any position (do not leak) and are safer for the environment because of this. One downside is the increased cost. Also, charging systems have evolved along with the battery type, allowing greater control of charging current via sensors and computer controlled adaptation.

The battery in BMW E60 models is located in the right side of the trunk, behind a trim panel. When replacing your battery, be sure to use a high quality unit. Replacing the battery can be done in a short amount of time. Read the battery connection notes before disconnecting the battery. Before disconnecting your battery, remove the key from the vehicle and store it in a safe place and note the radio presets. When the battery is reconnected or loses its charge, the following items may need attention (depending on vehicle equipment). You may have to reset your clock, enter the radio presets, initialize power windows, initialize the sunroof and normalize the steering angle sensor. Once your battery has been replaced, you will have to register the new battery with the vehicle's computer system. This tells the DME the age and health of the battery to ensure proper charging.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you are working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users. Do you have questions or want to add to the article? Leave a comment below. When leaving a comment, please leave your vehicle information.

Charging battery: You can connect a battery charger directly to the battery or under the hood at the positive (+) and negative (-) grounding point junctions.
Figure 1

Charging battery: You can connect a battery charger directly to the battery or under the hood at the positive (+) and negative (-) grounding point junctions. The battery junctions are located at the left front strut tower. The green arrow points to positive, while the yellow arrow points to negative. However, I suggest removing the battery from the vehicle when you need to charge the battery. This will avoid filling your trunk with gas vapor that the battery emits during charging. Follow the manufacturer's instructions on settings and using the battery charger.

Jump Starting vehicle: A vehicle with a discharged battery can be jumpstarted using a good battery or a good battery in another vehicle.
Figure 2

Jump Starting vehicle: A vehicle with a discharged battery can be jumpstarted using a good battery or a good battery in another vehicle. When jumpstarting: Be sure to work in a well-ventilated area. Batteries can produce an explosive gas. Wear gloves and eye protection and if battery acid comes in contact with your skin, immediately flush with water and seek medical assistance. Move both vehicles close together but do not allow them to touch. Turn the ignition OFF in both vehicles. Connect one end of the positive jumper cable to the positive (+) battery terminal of the vehicle with the good battery. Connect the other end of the positive jumper cable to the positive (+) junction terminal (green arrow) vehicle with the discharged battery. You will have to flip open the lid on the positive (+) junction connection. Connect one end of the negative (-) cable to the negative (-) battery terminal of the vehicle with the good battery. Connect the other end of the negative (-) jumper cable to the negative (-) junction terminal (yellow arrow) of the vehicle with the discharged battery. Start the engine on the vehicle with a good battery. Allow it to idle. Then raise the engine run rate to 2000 RPM. Next, start the engine of the vehicle with the discharged battery. Once the vehicle with the discharged vehicle starts, shut OFF any electrical accessories, radio, HVAC blower, etc. Carefully disconnect the jumper cable in the reverse order you connected them in. Allow the vehicle with the dead battery to idle to recharge the battery.

Replacing battery: Working in the trunk on the right side, using a flathead screwdriver, twist the trim panel locks (green arrows) counterclockwise 90° then remove (inset) them.

Replacing battery: Remove the battery trim panel cover from the trunk.
Figure 5

Replacing battery: Remove the battery trim panel cover from the trunk. Pull the side closest to the trunk opening away from the fender and rotate it toward the spare tire to remove it.

Replacing battery: Using a 13mm socket, remove the two battery hold down fasteners (green arrows).

Replacing battery: Using a 13mm socket, remove the two battery hold down fasteners (green arrows). Then remove the battery hold down (yellow arrow).

Replacing battery: Using a 10mm socket, loosen and remove the battery hold down (green arrow).
Figure 7

Replacing battery: Using a 10mm socket, loosen and remove the battery hold down (green arrow).

Replacing battery: Using a ratchet and a 10mm socket, disconnect the negative (-) battery cable (green arrow).
Figure 8

Replacing battery: Using a ratchet and a 10mm socket, disconnect the negative (-) battery cable (green arrow). Move the negative (-) cable aside and cover it so it does not accidentally come in contact with the battery terminal.

Replacing battery: Release the locking clip and open the battery safety terminal cover.
Figure 9

Replacing battery: Release the locking clip and open the battery safety terminal cover. The photo shows the lid open. There is one plastic lock you have to release by pulling up. Then using a ratchet and a 10mm socket, loosen the positive (+) battery cable (green arrow). Lift the positive (+) battery cable off the battery and lay it aside.

Replacing battery: Move both battery cables toward the spare tire and away from the battery.
Figure 10

Replacing battery: Move both battery cables toward the spare tire and away from the battery. This gets the cables off the battery to make removing it easier. Then disconnect the battery vent hose. The vent hose is located at the front of the battery, near the positive terminal.

Replacing battery: Lift the battery up and remove it from the trunk.
Figure 11

Replacing battery: Lift the battery up and remove it from the trunk. Be careful and make sure you have a good grip; the battery is quite heavy. You will have to move cables around and keep them out of the way as you remove the battery from the vehicle.

Replacing battery: Clean the battery compartment thoroughly.
Figure 12

Replacing battery: Clean the battery compartment thoroughly. Clean corrosion from the battery cable ends if present. Before installing the new battery, check that the battery vent line (green arrow) is not pinched, in good condition and properly routed. Replace it if needed. Install the battery in its compartment and attach the vent line. Connect the positive (+) cable. Next connect the negative (-) cable. Install the battery hold down bracket. Then reassemble the trim cover and trunk carpet.

Replacing battery: Once installed, you will have to use a BMW scan tool to register (green arrow) the battery.
Figure 13

Replacing battery: Once installed, you will have to use a BMW scan tool to register (green arrow) the battery. A capable BMW shop can do this. I recommend doing it immediately after replacing your battery.

Andy Comments: Hello, I am Andy and I would like to piggy-back on Daniel question from 3 Mar 2016. Over the last 60 days my 2008 E60 550i began loosing time on it's clock at a rate of 3 - 5 minutes daily even after I reset the correct time. Sometimes the time and date disappears on startup and has to be reset. I have not experience any starting problems however when I look at the battery today I notice the green eye on the battery no longer glows. Is this an indication of future battery or charging problems. I only had the car for 2.5 years and do not know the age of the battery. the date tabs were not set at the last replacement.
Thanks for your comments.

  Followup from the Pelican Staff: Batteries usually last about 5 years. The eye is only one cell. Best bet is to have the battery tested, if weak I would replace it. - Nick at Pelican Parts  
PhilB Comments: When replacing a battery can you hook up a 12 volt auto battery at the jump starting terminal to preserve your code settings?
October 17, 2016
  Followup from the Pelican Staff: I would not recommend it, if the cables touch when you have the battery out electrical damage can occur. - Nick at Pelican Parts  
peter530xit Comments: I think it's important to note that the battery does not need to be physically removed from the car but rather electricaly disconnected from the car.
May 29, 2016
  Followup from the Pelican Staff: Replacement? For what reason? - Nick at Pelican Parts  
Al Comments: I have a 530d se and fitted a new Battery, I still need to charge from time to time. My charger indicates it is for cars up to 1800cc Is this information correct as I have received information to the contrary, Kindly advise
May 23, 2016
  Followup from the Pelican Staff: You may need a new alternator. I would first figure out why it isn't charging. - Nick at Pelican Parts  
Daniel Comments: My bmw E60 2007 keep on giving me a late time 5~15min late on every time I start my car. Any idea what's goes wrong?
Cheers, daniel
March 3, 2016
  Followup from the Pelican Staff: What do you mean by late time? I don't follow. - Nick at Pelican Parts  
Sebon Comments: Which scan tool mentioned in article I should buy for battery registration? My car is bow 535xi sedan.

February 10, 2016
  Followup from the Pelican Staff: You will need and advanced BMW scan tool. Autologic Assist or BMW ISTA. - Nick at Pelican Parts  
Tphung Comments: What is a Deutronic?
February 6, 2016
  Followup from the Pelican Staff: A vehicle power supply. - Nick at Pelican Parts  
Tphung Comments: My BMW E60 has been sitting in the garage for the winter, can I trick charge it?
February 4, 2016
  Followup from the Pelican Staff: Yes, but remove the battery before charging. - Nick at Pelican Parts  
Olly Comments: My car started losing voltage and just about all alarms popped in. The original 110Ah wet battery was 11years old, so I replaced with a new original BMW same type, and registered the change in the car ECU. Problem is that using a "Sigarette-lighter voltmeter", I see that the car doesnt start charging the battery before after I have driven like 6-8miles. At that time the voltage jumps from like 11,9V to 15,0 weather is cold here. After that, it will charge from the start evertime I stop and start the car. But after resting overnight, the same happens. Need to drive 6-8km before charging starts. Starting to think maybe my old battery was ok. Is the "delayed charge" normal?
January 12, 2016
  Followup from the Pelican Staff: The tester you are using is not a good way to check the charging system. You will need to check charging system voltage and current at idle no load and under a load. Don't trust what you are seeing with yout tester. - Nick at Pelican Parts  
Laura Comments: When replacing the battery where is the battery vent supposed to be properly routed to? I dont ser that in the illistration. Is it to be connected to something? I see it standing alone.
December 2, 2015
  Followup from the Pelican Staff: The hose runs through the body, at the bottom of the battery tray. - Nick at Pelican Parts  
Charles Comments: The text next to figure 13: "Replacing battery: Once installed, you will have to use a BMW scan tool to register green arrow the battery. A capable BMW shop can do this. I recommend doing it immediately after replacing your battery." implies I have to drive to a BMW dealer to register the new installed battery. This means I have to drive about 26 miles to get there. Is that a problem?
October 21, 2015
  Followup from the Pelican Staff: 26 miles should b e fine. It is the long term charging pattern that would be bad if not adjusted. - Nick at Pelican Parts  
West Comments: I have a question about charging your battery. Is it really necessary to remove the battery out if I want to charge it? I know u said so it removes gas build up in the trunk but if I was to leave to battery on and just charge it how it is, will that damage or harm my car in any way? Thanks.
August 4, 2015
  Followup from the Pelican Staff: If you do not have a vehicle power supply, like a Deutronic, the charger (smallest amount of a/c voltage) can damage the electrical system. Not worth taking the chance. - Nick at Pelican Parts  
Jett Comments: I'm new to this battery replacement procedure. My question is why recharge isn't that the responsibility of the alternator? Will a regular battery charger or a part store be able to recharge the battery?
April 4, 2015
  Followup from the Pelican Staff: The alternator does charge the battery and supply the vehicle with the needed electrical current to operate. At times a battery may become discharged, then you would have to charge it.

Sure, most chargers will work. As long as the battery is removed from the vehicle. - Nick at Pelican Parts
 
Rick Comments: Is the scan tool something I can buy and if so, where could I find it? My car is a 2007 530xi.
February 13, 2015
  Followup from the Pelican Staff: It depends on what functions you want it to perform. For code reading and clearing, we can get you set up. Give our parts specialists a call at 1-888-280-7799. More advanced stuff, you will have to look at professional models. - Nick at Pelican Parts  
Miki Comments: Does the same registration procedure applies to when the same battery is removed from the car, recharged and installed back into the car? I assume that charging system will not be aware of the new recharged condition of the battery until reset or am I wrong? Bythe way my car is bmw e60 530i 2004.
October 29, 2014
  Followup from the Pelican Staff: No, only when replacing. No need if just charging it. - Nick at Pelican Parts  
Miki Comments: Thanks for the reply Nick. I'm completly aware of registration procedure when replacing old battery with new battery on bmw e60. Let's stick to procedure of recharging a battery off the vehicle. In the article you suggest to remove the battery from the vehicle when charging it, due to gas build up in the trunk. When you install the same recharged battery back in to the vehicle, do you have to reset the ibs, the same way as when installing a new battery? I assume that charging system of the vehicle will not be aware of battery beeing recharged or am I wrong?
October 29, 2014
  Followup from the Pelican Staff: No, only when replacing. No need if just charging it. - Nick at Pelican Parts  
Miki Comments: How will the IBS sensor se the battery which has been charged off the wheicle ?
October 27, 2014
  Followup from the Pelican Staff: The IBS looks at current. If you are asking why the module needs to be reset. The charging system adapts to the voltage and discharge rate of the current battery. If you do not tell it it has a new battery the battery can fail prematurely. - Nick at Pelican Parts
