General topics » Replacing original 2016 Battery

Having no indications of battery trouble, but a few recent throttle fault warnings, I'm replacing the original battery (March 2016 build) with the full-size YUASA YTX14H. The part-size original battery provided over 5-years of service for more than 27,500 miles.

I also have great luck with YUASA batteries. Did you keep in on a charger at all?

The OEM battery is a part-size battery. Your replacement ETX14/YTX14 will fit when the Styrofoam spacer is removed.

ETX14 dimensions 150 x 88 x 145 mm East Penn Website
YTX14 dimensions 150 x 87 x 145 mm Yuasabatteries Website

No point going for the smaller OEM battery, take advantage of the full size and remove that styrofoam under block.

yes, I'm sure the BMW designers pull a standard battery off the shelf when they design the battery box then the accountant comes along and says we have these super small Brazilian batteries costing 27p so use them with a spacer. Although my 2016 OE batteries have been durable with the XR lasting 4 years and the RS one is 5 years old next month. Neither has been on a charger very often, especially the RS that is ridden more often in winter.

Replaced both the R1200RS March 2017 original mini battery (bike already in stock so battery age unknown)
Plus the 2005 R1200ST (at least 7 years old) larger correct battery - both were bmw units.
Replace with two full size Exide batteries from nippy norman a couple of months ago, same battery.
Usually the ST is hard wired to an optimate since new and the RS uses the bmw charger via the mini accessory socket.
Can say both bikes fire up quicker and run better - maybe 'lazy' battery or trying to justify purchases?

Funny thing is - batteries were packed 'layed down - base to base - in one box - transporting as marked 'up arrows' would have kept both on their sides.
Box delivered 'upside down'anyway, so any 'right way up' advice was unseen or ignored?

No leakage in packaging, left upright 24 hrs before charging and then fitted - both were 12.4 - 12.8 volts as supplied.

I recently replaced my OEM with a Shorai Lithium Iron battery. Put both on a scale at work and the Shorai came in at 2.5lbs with the OEM at 10.5lbs. Virtually identical dimensions and still cheaper then what my local BMW dealer wanted for another OEM battery.

Is there a specified period whereby the battery in an RS should be changed?

My RS is 2017 with 12k miles, original battery. Everything appears to be running fine (going to regret saying that!)...should I consider a new battery?
