BMW R1200RT/R1250RT Forum

I'm looking for an aftermarket battery for my 2011 R1200rt. I found a Bikemaster that fits but the AH is 16 or 17 instead of 19 as per manual specs. Will this be a problem? Any suggestions re Gel vs. AGM or manufacturers/retailers? Any help will be greatly appreciated. Thanks. Roger.

Which one, http://online.fliphtml5.com/lxnd/cjbv/#p=22, they offer four for the RT, http://bikemaster.com/catalogsearch/result/?q=51913

Highly recommend a Motobatt.
I think the part no is MB51814.
AGM 22AH
Cheers.

BikeMaster do a conventional battery with a capacity of 19, http://bikemaster.com/conventional-battery-6730.html

Bikemaster seem to be US based only.  Their gel batteries cost more than an OEM one. You wouldn't believe the damage a lead acid battery can do if it spills.

The BikeMaster TruGel Battery costs $167.95, http://bikemaster.com/trugel-battery-5142.html

The BMW OEM one costs $190.61, http://www.sierrabmwonline.com/product_ ... 19as-p-371

$168 is £131. Same price just about as an OEM.  Do we know where he is.  I assumed UK.

My guess is the US, "BikeMaster is distributed exclusively in North America by Tucker Rocky Distribution".

The BikeMaster battery has a 2 year warranty, https://www.youtube.com/watch?v=fZ4u1LAY0_0

I wasn't sure as his first post was all about an Optimate and he types (English)

Optimate are available in the US.

One of US will be correct, the suspense is killing me.

Now if Steinar made it impossible to register without adding your location life would be much easier

No, that wouldn't be half as much fun.
