In trying to keep full records of my repairs I
have to document the easy and difficult repairs, right! This might
come in handy for a n00b, but most of you seasoned individuals could
do this blind folded. Note: I didn’t say with one hand tied behind
your back, why? because these batteries are HEAVY.
Scenario, car sat for a couple days, then I
started messing around with some electrical stuff and this killed my
battery. I recharged it at a slow pace but it just wouldn’t hold a
charge, so a new battery was needed. The battery I am replacing was
just about 4 years old, so I feel I got some good life out of it
given the electrical gadgets I have installed in the car.
I opted for the BMW branded battery which was
list $180, but $161 with my BMWCCA discount. So basically, less
core and discount, my total out the door with tax was $173.23 for a
battery part number
61 21 6 901 815. The “werker” brand at batteries
plus was $159 + tax.....
Not much needed,
20 minutes or so, 10mm wrench or socket and you’re ready to go.

Here’s a shot of the new battery, look at
the blue circle and you might be able to notice the nice green
dot. The red circle just shows you specs.

Here’s the replacement procedure. There
are basically 5 steps before you pull the battery, 1-4 are
shown below and then 5 which is the vent hose removal will
come later. All 10mm except the wing nut on the jack. Remove
everything is this order:
|
 |
|
Remove this long bolt and the plate it threads through. This
holds the battery in place: |
 |
|
Then remove the negative battery cable, I
wrapped it in a towel as you’ll see below: |
 |
|
Then switch over to the other side and
remove the positive battery cable, I wrapped it in a towel as
you’ll see later:
|
 |
|
Pull the positive cable off:
|
 |
|
Next carefully slide the battery towards
the rear of the car [the tail light area], see the blue arrow,
and remove the vent tube. The vent tube nipple just pulls
out:
|
 |
|
Now grab these two handles and get up
your strength, is heavy and awkward so take your time:
|
 |
|
Now get ready to put the new one in.
Once in and situated, slide it back if needed and attach the
vent tube:
|
 |
|
Again, it just snaps in:
|
 |
|
Now situate the battery and bolt the
plate in to secure the battery in place:
|
 |
|
Like so:
|
 |
|
Then hook up positive first:
|
 |
|
Then negative:
|
 |
|
Slide the jack back on the: |
 |
|
And attach the wing nut:
|
 |
|
And here’s the final result, looks just
the same as before doesn’t it.
