Would it be a total waste of cash to get a summer Lithium ion battery and keep the lead one for cooler weather? If they are both maintained I'd get twice the life out of them wouldn't I plus a few lbs weight savings on the battery for the summer.
 
Just went out to the garage and pulled the Yuasa MF oem battery out. It's now in the basement defrosting. I'll plug it into the charger later tonight. I bought a Yuasa Smartshot 900 charger.
 
Just for the fun of it I took my cheap multimeter and went to check on the battery I have equalizing to temperature. It was 12.45 volts. This is a battery that hasn't been charged since the beginning of December so that is the amount of drain from peak so it definitely needs charging.

Not sure why the interest in lithium ion for summer use for regular folks. What's the point? I can easily hold the lead-acid in one hand, I don't think a theoretical single lb or whatever it is savings in weight will make any difference in anything.

Did you not read the whole story? And what's with the slashes? Are you having a keyboard stroke??

He charged the battery over winter, went for a few rides, and then it died. It drained while running which is impossible unless the charging system wasn't charging the bike while running. Even according to your theory(3).... it was on a charger over winter so that's why it worked when he initially started it.... well the bike itself IS a charger while it's running... lol so why didn't it charge it enough to start it after he stopped it??

But hey, do whatever you want instead of testing anything first, makes no sense but it's your money!

for my bike the difference in weight is quite large, also for warmer weather use the lithium ion batteries are more efficient.

I don't get why you think checking ones charging system, or checking anything is not first and foremost, but rather go and spend the cash on a new battery ?

I just don't get it

Buy a multimeter for 10 bucks, do a few checks, and determine your electrical is in order, if all that passes, go get the battery load tested and see if it passes....

Why that is so difficult is not understandable, unless you are not mechanically inclined to perform these tests, then your suggestion of "get a new battery" makes perfect sense.....maybe you should call up Frekeguy and he can perfomr the simple taks of testing the electrical system for you, but I have a feeling you have more moeny to blow on new batteries, so even that would be a wate of effort....

OP, you will find how to test your electrical system in a manual, find it on the net if you don't have one, do the easy stuff, then spend the money on a new battery, at least the multimeter will be a great asset to your tool collection...even if it's only 10 bucks....

Nice try.....

Why don't you provide an answer other than buy a new battery.....why make the OP spend 80-100 bucks on a battery he might not need.....

I wish I had your disposable income......hey better yet, I'll just ask you to get me a battery each year and I will never have to worry about my electrical system at all.....

If you can't afford a $40-$80 battery then you got the wrong hobby.
You will get the answer in a few days. Wait for the OP.
 
It's not the cost of a new battery.......

What is the point of putting in a new battery if his electrical charging system is not doing it's job, all he is going to do is kill another battery in a few days, and what spend another 40 - 80 bucks on another battery......


Why not take the 1/2 hour or hour and go over the electrical system make sure it's working, have the battery load tested, and then you can say for certain it's time to get a battery.....

maybe your in the wrong hobby if you can't do that much at least, or have a friend who can do that much for you.....

Like I said seems you have more disposable income than you know what to do with......lucky you.....

It's actually a 6-8lb difference. Not necessary for most people but if your replacing your battery why not shed some lbs at the same time.

OP, buy a meter, check the battery, then check the charging system.

I charged once a month over the winter. put it back on the bike a week ago. Didnt ride it.. started her a few times. took her out today. Started np than stoped 3 times in a short 10 min ride around the block to do some errands. The last time it didnt start.


Does it sound drain? I know i know i should just get it check

Charging it once a month over the winter may not have been enough. I use a smart charger and just leave it trickle charging over the entire winter.
 
First thread I've seen where everybody's right. Buy a battery, multimeter, load tester, read manual, test everything, exchange battery for beer(optional) have disposable income.

Can anyone suggest the cheapest place to grab a Yuasa for 09 600RR. Every place seems to be $140+

Let me help you with this bike repair 101
1. likely an old battery
2. he wants to check the battery without a multimeter, uhmkay
3. battery has been charging over winter
4. battery is now dead and likely would need to be replaced...wait for it...wait for it...anyways
5. now you put in a new battery and check the entire charging system properly with a multimeter
6. he will have to replace the battery regardless...ride bike for an hour or 3 and check the battery again
7. now if NEW battery runs low he will know on restarts
NOW you know that you have another problem with the charging system likely the rectifier on that bike but none the less you will KNOW IT IS NOT the battery. Just put the battery on a good trickle charger and it will be fine.

or we would go with your idea and start replacing the MOST EXPENSIVE components to the charging system first.

new battery $40-$80 do it yourself 5 minute job + $10 multimeter
new rectifier iirc $300
new alternator I forget but likely in the $300+ range
labour to change the alternator, current shop rates ~$100 per hour plus taxes you can bet it will be at least 30 minutes

I did what you're saying. It was the charging system not the battery. Went through 2 batteries because I didn't check the charging system.

OP check the charging system too.
