That is the "older" version that BMW sell and is made by Battery Tender. The newer version is made by CTEK.

I've been using the CTEK charger on my cars for over 6 years now, both through the "jump" terminal under the hood as well as various DC sockets without issue.

What's wrong with using the DC socket in the vehicle? These battery maintainers are very low amperage...usually no more than 3A to 5A, way below what the socket is rated for.

One can buy that exact model, minus the logo, for ~%25 less on the net:
Battery Tender Plus...
Amazon.com: Battery Tender 021-0128 Battery Tender Plus 12V Battery Charger: Automotive

I have used my pair for a decade+ on the old one, and several years on my newer version.

I use the alligator clips on the underhood lugs.

Some posters here rave about the Ctek charging unit, of which I have heard/read nothing but good things about, too.

Skip the logo version from the dlr, and use the under hood lugs vs the cigar light socket, imo.

Short answer: Just drive it.

....I wouldn't worry about needing that unless you park the X for extended periods. Replace the battery every 4 years and make sure your alternator is charging what it should and you'll be fine. I've left the X parked for 3-4 weeks on numerous occasions without incident.

I am planning on parking it until sept . but I was thinking more in the winter when it goes below -30c when I was having issues starting the X this pass winter. I just thought because of the battery being in the back it was a long run with the wiring to starter causing the problem.( by the way I have no garage).
this charger only draws 1.5amps.

No Garage???

Two Words

Solar Charger

solar charger might not work at night though (thinking winter months) would be great during the day though.

I have parked my '01 3.0 for 5+ months in an unheated garage, (maybe -10 degs F on occasion), every other year for the past 9 years.

I use my old Batt Tender Plus, hooked through a mechanical appliance timer to come on a couple times a week for 12+ hrs. I have it connected to the under hood batt lugs.

Every other Spring, after sitting for 5+ months, it has started on the first turn.

If you don't have a garage, with elec receptacle, all bets are off...if you do, storing a car for a long time is not nuclear engineering. I do it to one of my cars, (Vette or X5), and all 3 m'cycles, every winter with no ill effects simply using 'standard storing methods' and common sense.

Can you explain the bold portion?

Block heater (Yes, I know BMW doesn't recommend them), Zero (Arctic) weight oil, and a solid battery does wonders in those kinds of temps. Routine -30*C temps is just one of the way this place earns its "WinterPeg" nickname....

While this last point is more of a "provisional". Try using mid or regular grade fuel in the X during those extreme cold snaps. It works for some, not for others. I can say, however, that in my case, in the extreme cold here (-30c which felt like -40..or colder) the X fires quicker with regular grade fuel, than it did when I ran premium. Running shell's V-power (yeah, the branded gas discussion that's been hashed to death....But I use shell in all my rides) in those cold months caused the X to stumble for a second or 2 after it fired. The local dealer here even had a bulletin on the service counter about using lower grade fuels as they get inundated with cold start issues during cold snaps that usually boil down to shit just being too friggin cold here.

I'm using the version with alligator clip



Reason being: our 2009 328Xi definitely requires the alligator clip version because the cigarette lighter socket is not hot with the key off. The battery for this vehicle was on its 6th yr ( since 2008), Im planning to change on its 8th yr.

I agree with upallnight and others, that there is a better product out there than BMW battery tender. With the capability of trickle charger and full/fast charger. Do a research in your own about this.

The problem is you have no garage (with an outlet), even if you use the updated DC plugin, my gut feeling it is not right charging out in the freeze zone ( I can be wrong).

I always keep our m3 hibernate the entire winter with a trickle charge, and once in a while plugin the other two vehicles.


Good luck!
