Every time I go to start my bike or I turn it off only for a minute, I always make sure the bike is either completely on or completely off. I'm always worried one day that I'll leave it on but not running and it will drain the battery. I feel like it wouldn't take long either but I honestly have no idea.

I was wondering if anybody is able to tell me how long the battery could go without dying while the bike is on but not running. I know there's a lot of variables but lets just say a year old stock battery with regular use. I also don't run anything else to my bike so there's nothing else drawing power and I don't have HIDs.

I'm really just curious about this because I feel like it would drain quickly. Thanks in advance for any help.

I left it on at a track day by accident once, and within an hour and a half it was dead. This was with an older battery that got replaced the following year though, so a newer battery would probably last a little better.

That's actually way longer than I thought it would last. I was sure anything close to 30 minutes would kill it haha. I'm even afraid of leaving it on for 5 minutes by accident lol

If your battery only last 5 minutes, there's a problem haha

I would guess that there won't be much drain of the battery if you leave it on for less that a minute. But really, if you do leave it on for several minutes, the question would be do you then drive it long enough to recharge what you have drained. If you continue to do this without riding enough to gain back the charge you lost, then one of those times it's gonna drain low enough not to start. Now you're stuck.

I would just try to get in the habit of always turning it off. Then you shouldn't have anything to worry about.

Well I've never tested it before so I have no idea how long it lasts. I don't really wanna test it either haha. This is my 2nd bike and I just have no idea how long these batteries last and I'd hate for it to die while taking a 10 minute break haha

Well I do always turn it off but you never know. Like I said this would probably happen while I am taking a nice long ride with some friends and we take a quick break. So I'm sure I would be able to recharge it back up.

Yeah I guess this wouldn't be a problem if your riding that far. I guess what I don't understand is why you leave the bike on. Is there some perceived benefit? If you just get in the habit of always tuning it off, you eventually can trust that your unconscious brain will always take care of that for you and you would be less likely to get caught on a long drive with a dead battery. I know on those long drives sometimes the breaks get longer than we think. Just saying, maybe its better to be safe than sorry.

I would say dead in 30 minutes to an hour if left on. I'm still on my 2009 original battery. Its plugged in to a tender most of the time.

This actually happened to me yesterday. I ran a quick errand, got home, hit kill switch, but left key in the On position.

I didn't time it, but I'd say it was left On for about 30mins or so. Keep in mind, bike was already running previously, so one head light was on. Anyway, after about 30mins headlight was on, but voltage had dropped enough to not start the bike.

Shit happens. Battery is a little over 2 years old.

I'm guessing all the effort to install the replacement stator went well?

OP, I've left bikes on without running a few times over the years..... it's a good thing to know how to bump start a bike.:naughty: Usually, if it has enough juice to run the injectors up to pressure there's enough in there to run the ignition as well..... if there's not enough to turn the motor over as well; use your legs.

 

[ZX6R Wallis]

Thanks for all the good info everyone. I am in the habit of completely turning off the bike as I do that every time but I have caught myself almost leaving it on once. Mistakes happen and that's why I was curious about all this.

Reserve time on batteries

Most reserve time on batteries are 60 to 90 min max.

On my previous bike I did this many times. It was a supermoto so my brain said dirt bike... Just kill it and get off like your kx. Took at least a dozen times going dead over two years to ruin the battery, so if you do this a couple times dont fret too much.

Yea.. Good memory. I had worries that the stator was getting a bit too hot, but its been running great so far.

Friend left his ZX-10R on for about an hour roughly and couldn't start the bike up after.

Didn't need to replace the battery just needed to charge it up after the incident and worked fine after that.

This is why i turn the bike off via key. I never use the kill switch. I believe the manual states to use the key for turning off the bike to avoid this exact problem.

Same here. Also I believe the kill switch is for emergency use? Maybe that's for a different topic not in this thread.

U can always bump start the bike if u forget the key on and drain the battery.

I've left my bike on for 20 min plus wile working on it started fine I wouldn't make a habit of it its alway good to have a routine of turning it off in my opinion it comes down to not being lazy it takes 3 seconds to turn it off keep that habitat going
