Question Battery Question

I am starting to think my orig BMW gel battery may be headed south...slow starts in the AM about 20-30 degrees here....but it starts and quickly goes into a little bit of fast idle....am thinking of the Odyssey pc680 but also see a PC680M( i think thats it)..anyway...it retails for 85 and 95 respectively...question is what is the difference...also is there some sort of modification needed?..also...is that a good price?...and is it ok to disconnect the battery and will i need to reset any codes or anything?...I have an 03 LTC...tks Mikey

The 680 and 680MJ are the same battery, except that the MJ has a metal jacket. This isn't necessary, but doesn't hurt either, so get whatever one is available.

The battery should fit into the same spot as the factory battery without any trouble. Some people have added adapters to the battery terminals to make it easier to get to the cables, and to add a few more cables, but those aren't strictly needed.

After swapping out the battery, you should reset the throttle position sensor. Turn the key on but don't start the bike. Turn the throttle full open then full closed, then go open and closed again. Then start the bike and ride off.

All lower 48 states plus Alaska on the K13GT in two weeks . . .

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Mikey,

I don't know where you're located but I had to replace my battery and got the Odyssey from BatterysPlus. Here is the page with the batteries they have for the KLT. http://www.batteriesplus.com/findBat...d=524524242424
They had it in stock and took my old one off my hands. Use there zip code finder for a location near you. Call them for a price. I think mine cost me $85ish out the door.

Just a WalMart battery

For the sake of throwing a fly in the ointment...this past year I replaced my stock battery with the BMW gel battery. Purt-n-near cost me $100! Ouch! Next time, I think I'll go up to Wally World and see if they have a 12v battery that is the same size, and give it a whirl. After all...12 volts is 12 volts, right? And if it costs me under $50...I think I'm ahead of the game. The question is, will I actually do it when the time cometh? I can't answer that today.

I'm late to the party as usual....

Ken, are the adapters you mentioned required, or a matter of convenience? It sounds like from your comment that the factory cables will work without the adapters, but they may be a bit of a PITA....

I am running things through a Blue Sea fuse box, so farkles shouldn't be a problem. Just don't know if (or how easy) the 'factory' cables will work.

Also, for the uneducated, what advantage is the Metal Jacket?

My '03 has the gel battery and has been slow to start the bike in the 20 degree weather even though I plug her in to the charger every night.

Thanks in advance...

Ok, I answered part of my own post --- "The PC680MJ (MJ=Metal Jacket), means the battery is housed in a metal jacket. This enables the battery withstand higher ambient temperatures. The PC680MJ is rated to withstand temperatures of 176 degrees Fahrenheit vs. the standard PC680 is rated at 140 degrees Fahrenheit."

Thanks,
