Does anyone have a part number or suggestion on a replacement battery for a 2007 R1200RT? The OEM battery is rather expensive and the original only lasted two riding seasons.

Here is the 'part number' for what is in the R1200RT:

BMW Battery #: 61.21 – 2 306 200

As for replacing it, I have an '05 R1200RT with the original battery still going strong.

This Spring, I did drop in a Westco that a fellow BMW rider gave me free, but had that deal not come along, I'd still be running the OEM from '05, which now rests on my workbench, charged up once a month as a standby.

Not sure why you only got 24 months out of it?

Hi.

I too have an 05 R12RT with the original battery. Does just fine.
I recently changed a battery on my K75 after eight years (8). No reason. I just figured that it is at the end of its life.

Wow, I hope my wife doesn't develop the same attitude about me. She's had me way over 8 years; but, my charge is down a bit and my starter is dragging. ;)

As long as your warning lights go off when you get up out of your chair to move, there is still some juice left in you. I'd mention a trickle charger, but I hate to use that word in the presence of old men. :whistle ;)

I ordered the UB12220 from www.BatteriesASAP at 42.95 yesterday. 7.00 shipping to Massena NY. Its a 22Ah battery that fits fine in the RT.

The local BMW dealer quoted me 327.29 for the OEM replacement. When I questioned the price the service tech said it was because of the CANBUS system requirements. :bolt

Lots of folks have used the 'alternate' battery, either the UB12220 from Batteries ASAP ( $42.95 ) or the UB22-12N from eBatteries ( $74.95 ) with absolutely no issues.

Oh, and BatteriesASAP has a 5% discount coupon ( Z13109B5 ) good until the end of March.

What is your rule of thumb for battery replacement?
Is there a fixed rule? I've heard 3 years. I've heard "hey, I don't buy new until the old dies". I don't know if I like the latter response, seeing it could "die" while you are on the road.

I have an '07 RT as well. Had it on the official BMW charger on and off all winter. I'd let it sit a week or two then throw on the charger and let it cycle. Bike fired right off last weekend, first start since November.
So is my battery good or . . . . .

Thanks for the replies everyone. I really just want to replace the battery to make sure I don't have any issues on the road this year. My wife and I take a lot of long trips and I don't want to worry about the motorcycle not starting when we're hundreds of miles from home (or a dealer). The engine was turning over a little slow last fall so I figure it's time for a replacement. I had a 2003 K1200LT and a 2004 K1200GT and in both bikes the batteries only lasted two years. Maybe it something I'm doing to shorten the battery life?

The terminals are not facing the same direction as the original battery. Does the UB12220 come with adapters or did you purchase them separate?

Good question, (adapters...), I doubt the battery comes with any adapters since it is sold as a 'universal' battery. And from what I have read elsewhere there wasn't supposed to be any fitment issues. Drop it in and go...However I haven't received the battery yet so I guess I'll know better when I get it home.

For that price I could afford to have adapters made, ( or make them myself ) out of pure silver ;) .

My understanding was the most you have to do is use a piece of cardboard to fill the 1/4" space in the stock battery holder not used by the replacement battery. Oh, and drill/file out the terminal openings to 1/4" size. They are just slightly too small for the stock bolts.

I'll be happy to post comments after I get the battery home and installed.

Thanks Jim. Please let us know how the installation turns out.

The battery(from BMW) is fully warrantied for 2 years, not prorated either! Are you past the two year mark??? All replaced batteries by BMW are 2 years also, so keep it in mind:) Randy

Does BMW require proof of proper battery maintenance, i.e. ownership of a BMW charger, perhaps.

I've a dead battery (despite my BMW trickle charger reading green). Where can I read the steps to choosing a new battery and then to replacing it? What kind of battery should I buy? What dangers are there to this process that I must avoid? Will I need tools I might not have already as an average somewhat handy homeowner?

The battery is easy to replace. Wesco and Odyssey I think are the most popular. Take the old one out, put the new one in. I didn't need any adapters on my Odyssey. The wires I just twisted 90 degrees and mounted them flat on the battery.

Piece of cake.

Just keep in mind that the battery (at least, on an '07 RT) is a gel cell...

In disconnecting the battery, negative cable first then positive. Installing battery positive first then negative. Your bike and wrench will be much happier this way;)

I just installed a Shorai battery for my RT. http://www.shoraipower.com/

It has received good reviews in a couple of magazines, so I am trying it. Only been in 2 weeks, but so far so good! Starts right up!

Cheers,
