Battery Problem

[RichInFla]

This has happened twice so far, and I've searched through the posts but can't find anything relating to what's happening. Might be a little long, sorry. First, no new equipment installed since I bought it. So, about a month ago, the bike sat for two weeks and wouldn't start, so I bought a charger, charged it up, and the next morning it started right up. Rode for about 3 hours. This weekend marked the end of another two week "rest" for the GZ, so Friday night I put the charger on it. Started right up Saturday morning and I rode for about 3 hours. This morning, went to go for a ride, it started right up, but I was coming to a light after about an hour of riding and it just shut off. Electric start did nothing, tried push starting (which I was successful with about a month ago), but it wasn't happening this time. Luckily, my HD riding neighbor had a truck and ramp, so he came and got me. Put the battery on the charger when I got home and it was at 16%/2A. :??:

He said it might be my "stator" (he pointed to a little metal thing with wires coming out mounted the frame right under the seat) or "alternator" (don't know where that is or if the GZ has one !!). He said the battery is just supposed to start the bike, but mine was "running" off the battery, draining as I was riding. He has a riding buddy who has the same problem (different bike). He said he can ride for about 4 hours, then it'll shut off and just won't start.

Okay, GZ Wizards, I'm in need of your infinite wisdom, I can't afford another trip to the "shop" after just purchasing tires and brake pads ! Is there anything I can try myself, I can follow instructions !! Thanks all !!

If the battery is over 3 years old, it's probably ready to replace. Take yours to the battery store and have them check it before anything else.

I'm not saying you need a battery, but I do suggest checking that first. Downtime kills 'em.

Can you actually tell if a battery is bad once it's fully charged ??

[Sarris]

They'll do a load test. It'll tell how well it keeps a charge. Worn out batteries can "take" a charge, but not "keep" a charge.

It's easy enough to get out, and most battery stores check them for free, so why not check that first?

Yes, **I** can. The question is can YOU ?? :biggrin:
(Sorry, couldn't resist.)

I'm assuming that you do not have a multi-meter. If you did (about $15 at Radio Shack), battery and charging system "rough" tests are pretty easy.

Like your friend, bike shops are often too quick to make ASSumptions and do the wrong thing.

Ride it to an independent battery shop....like Interstate....or an auto shop that sells lots of batteries......like Farm & Fleet, but call ahead to be sure they stock the battery for your bike......and take about $90 with you because what you have described so far is the classic story of an old, sulphated, worn out battery.

If you trickle charge it every night, it will get you to work and back every day.......for a few days or weeks. Then suddenly it will get you there and will be dead for the return trip.

What does this mean: "it was at 16%/2A" ??

Sorry, the charger I bought tells me the "% Charged" and "Amps". I have an interstate dealer down the street, so maybe I'll take it there. They close on Sunday at Noon, so it'll have to be during the week. The last time this happened, I called them and they said it'll take 3 hours to charge a new battery, which is why I went and bought the charger. If the consensus is "bad battery", I can handle that !! Thanks.

Can't reach a valid consensus without sufficient data.

You can make a rough test just with your fancy charger, though. Charge it until the charger says 100%.....or close to it. If it never goes above 90%, that's a good indication of a bad battery. If it does go to 95% or more, note the % charge, disconnect the charger and let it sit for 24 hours. When you reconnect the charger, it should not be read less than 5% below the previous charge level and should return to the first percentage withing a minute or two.
A healthy battery will NOT self-discharge any significant amount in 24 hours.

At this point, I think the consensus is: A trip to the Interstate store is in order.

Okay, more data...Coincidentally, I charged the battery yesterday until about 6:00 PM, which it stopped at 100%. Put it in the bike and it fired right up. Put it in the garage and removed the battery in anticipation of taking it to Interstate during my lunch break today. Ended up down in another part of town for work and never made it. Just went out and took it out of the Jeep and hooked it up to the charger (7:00PM, 25 hours later). It was still at 100%/13.1V.

Does that help/say anything ?? Thanks.

Yes. That tells us that your next action should be to take the WHOLE bike to Interstate.
At this point, I would say that it is not likely the battery is bad......although still possible.....and it might be the charging system at fault after all.

It is also possible that you just have/had a bad connection at one of the battery posts or at the other end of one of the main cables.

Let Interstate test.

[RichInFla]

Interstate can test the charging system ?? I thought you were joking about taking the whole bike to Interstate (thought all they tested were batteries) !! My neighbors recommended a cycle shop here in town, but I don't know if they work on Suzuki's. If Interstate Batteries can test for something else, they are right down the street !!

And sorry, incorrect info on the charger. It tells me % and Volts.
