Hello,

I have a quick question concerning the BMW OEM battery for the R1200RT:

I need to replace the original battery (after more than 6 years of use) that came with the bike. I am planning to buy the OEM battery from the dealer. Since I would like to pick up a battery that was manufactured not more than 6 month ago I am wondering if the battery has a manufacture date on it. If it does, where is it located? How old of a "new" battery would you still consider buying? Is the 6 month a good cut off period?

Thanks for any info.

I can't tell you much on the BMW OEM (replacement battery's ) as to me personally they are WAY overpriced for a moderate to low quality battery.

(But) -If like the OEM original battery's there should be a tag on the side of the battery with "month & year" of battery build & a "sell or install by date".

Shorai makes a Lithium Battery that I have now. My original was from 08' and worked fine but like many with a big trip looming I went with it.
PS. The pads they give you to make up the size in the box, well just apply them to the battery instead of the box. Much easier and you can always put an OEM size back in later if so desired.:)

Shorai seems to be the way to go... nothing like saving 11 lbs or so.. and that weight is carried up high.

So the Shorai is $230 and the Westco is about $110 and less than that if you use the ADVRider discount. Now why would anyone want to use the Shorai? I am serious as I do not know the difference in the two batteries. What does the Shorai bring to the table that benefits me twice the price of the Westco?

You can get it for cheaper than $230... I've seen it for $180 or so.. 70 to 80% LIGHTER (and these are pounds up high, that is -top heaviness) can hold a charge for 1 year... these are the newest technolgy. Lithium polymer .. MC Product of the Year.. If you ever picked one up.. you would think it was a hollow for show "plastic model"!

Yes, it is more expensive.. that I'll grant you, that is then a decision you have to decide if the weight and the newer technology is something you wanna spend for.

Personally, so far anyhow, they do nothing to impress me as a long term high current motorcycle starting battery unless weight savings is a major factor in battery choice. Might be a good choice for racing or a light weight off-road bike.

The Shorai is a Lithium Iron construction. Strong points are light weight & long shelf life without losing charge.


Disadvantages are a need to have controlled re-charging, decreased capacity with age, so far unproven in long term motor vehicle use. Some can have a decreased extreme cold weather power output also.

The auto companies have been looking at them for weight reduction but so far there have been enough concerns & durability issues that they aren't currently being used for high current discharge conventional starting batteries.

They do seem to be working good in non automotive application for back up power supplies & such & for non high discharge starting applications.

Quite a few people now installing them as replacements in motorcycles & power sports vehicles but not enough long term power sports usage yet to prove them out or to show me they are worth all that extra money.

6 years is "moderate to low quality?"

You were very lucky... mine was giving up the ghost after little more than two years and my brother's died a sudden death one week out of warranty (it was replaced at no cost by BMW, no questions asked).
If you want an excellent bang for the buck battery I can only suggest you the Yuasa 51913. While it doesn't have the same monster starting power the Enersys ones (Hawker/Odyssey) have it's still a big improvement over stock.
The good news (for you) is that's an old fashioned battery, meaning you buy it dry and have to add acid to it. That means manufacturing date is much less of a concern than with a sealed battery.
The bad news is you will have to keep an eye on levels... but is it such a huge hassle?

The lithium batteries have been used in racing(automotive and motorcycle) for some time.
Only time will tell for our application.
And yes mine was $181 shipped.
