    You don't need a bigger battery unless you live in Svalbard - something else is awry. The stock-size battery will crank the bike very briskly if the battery and bike's starting system (cables, starter, starter relay, bendix) are in good shape.

    Before buying yet another battery, try two tests: first, jump-start the bike from a car battery, which will have way more capacity than the bike battery. If it cranks slow, the bike battery isn't the problem; second, make sure it's charged and then pull the bike battery and have it load-tested - that's the only way to determine if it can deliver the current it's supposed to. If it fails, replace it; if it passes, there's something else wrong in the starter system.

    Have you removed, cleaned, and reconnected both ends all the battery cables and the big cable to the starter? Connections sometimes look and feel good, but aren't.

    This thread should be in Hexheads

    If battery passes the load test and all connections are clean, check out the starter. Brushes may be worn or crudded up.
    May be an issue with the magnets as well (common to earlier oilhead starters, not so with hexheads)
    You did not reveal the mileage.

    Ufda happens..........

    It's all about the details.

    Good. How about the other (non-battery) ends of those cables?

    Size does matter

    What are the battery specifications? Cold Cranking amps and the like? Compare the specs for your Interstate bsl 1116 sealed agm to what is recommended for your bike and make sure the battery specs are what is recommended for your bike.

    How old is the battery? Do you keep it on a trickle charger or are regular rides long and frequent enough to keep a good healthy charge in the battery?

    Has the bike always turned over slow?

    Before going to far looking for problems in your wiring or starter make sure the battery has the recommended specifications for your bike, always has a good charge and is not on just worn out.

    A 9 year old bike with 28,000 miles suggests to me the bike isn't ridden often and may just be enjoyed on short and infrequent trips, perfectly alright in my opinion. That kind of riding time will wear out batteries especially if you don't keep them on some sort of trickle charger during the down time.

    Don't go crazy looking for a wiring or starter problem until you are sure the battery is good and getting an adequate and often recharge.

    I got the bike this July with 24600 on it.. i put the rest of the miles on myself.. long rides and use a trickle charge when not going anywhere. The bike has always turned over slowly..
    but started up.. It seams to start with more "gusto" now, with cleaned terminals and wire ends. But I will check the specks and see if its too weak of a batery. It wouldn't surprise me if the person I got it from put a low end batery in the bike.

    Thx for all the comments ! Any brands of batery to be recomended? Hopefully will not have to buy one now?

    Bat Rays

    All sorts of bat ray suggestions on this forum. Anger solves nothing, just address the issue. It's one of those
    things where the more you spend the better you get IMHO

    One thing to remember about BMW motorcycles

    Some times the cheapest thing you find on one is the owner. I have had great success with Oddesy batteries. My 04 GSA (delivered in 8-03) is on its third battery, OEM battery died after two years, the first Oddesy was given to a friend after 6 years of faithful service and the second and current one is still cranking strong.

    When you do install a new battery I would strongly suggest attaching a fused battery tender lead/pigtail directly to the battery and securing the plug end some place convenient for easy access. You may already have that setup or may use the power outlet adapter plug, both work but in my opinion the hard wire directly to the battery is a better setup.

    I currently have Odyssey PC680-P batteries in the family RTs and highly recommend.

    I put a Yuasa GYZ16 in my R1200GSA, it has the same physical size as the stock battery but much more plate area and capacity. I noticed a difference in cranking speed on the cool fall mornings. Price was under $90 online.

    A failing starter exhibits the same sounds as a dead battery, especially when the bike is hot. Suggest you replace the battery and see if it goes away. I had a starter fail at only 7,000 on one of my BMWs, so its not unusual for that to happen in a bike with relatively low miles. It does that same "tick, tick, tick" sound and lights go low, as it draws so much juice. When its warmed up, the engine is harder to turn over.
    For what its worth, I have Odyssey PC-680s in all 3 of my BMWs, and am in year 7 on one of them with no issues at all. Keep them on a Deltran Battery Tender Plus 24/7 when I'm not out riding.

    I had the same symptoms on my recently acquired 07RT with 36K miles on it. I had the BMW battery installed by Haps in Sarasota and it made a world of difference.
