I posted a few months ago about the dead battery:

"I know this is yet ANOTHER dead battery question, but this is more of me confirming that what I've read is correct and that the steps I plan on taking are what you guys would recommend.

So I ride my Rebel mostly on short trips, 5 miles max, but I do use it daily. I also ride with the high beams on all the time (good for safety, bad for battery).

I understand that the battery only charges at higher revs and really needs longer trips to keep it juiced. So when it didn't start this morning, I was frustrated, but alas, not surprised.

Now, the bike only has 1,300 miles on it. I really don't think I should have to buy a new battery (I suppose I could be wrong). The lights still turned on with the key in, high beam light, kickstand light, etc. So I'm assuming there's at least SOME juice still in it, enough to get it started, and enough that its not completely dead. I mean, I didn't leave the keys in it, so I hope its not completely dead lol.

Here are the steps I'm planning on taking:

1. Go get a battery tender. 1/2 amp to 2 amps is what I read.
2. Jump the battery I have now with a car. Am I correct in that I can use my normal jumper cables, and all I have to do is connect them to the Rebel and my car and turn the car on, NOT start it, and it should jump? (If anyone has more detail about this procedure, or a link, that would be AWESOME)
3. Once the battery is jumped, I'll take it around the block, rev it high, and bring it home and plug it in overnight to the tender."


This worked...at the time. Now, I find that I'm having to tend it at least once a week or it literally won't start. Is this normal? Draining the Rebel's battery about once a week?

Some stats:
I ride about 40-50 miles a week or so, but the majority of that is 2 miles or less trips (to work, friend's house, etc).
I try to rev it higher to hopefully charge the battery while I ride...I don't think I'm doing much.

Anyway, if you guys tell me this is normal for someone who does such short trips as mine...so be it, I'll be more diligent about tending it. If not, I suppose I'll get a new battery.

If I need a new battery, how much should one cost and is it an pretty easy do-it-yourself instillation? Thanks for the info.

I think your battery has been damaged from being drained too many times and you should buy a new one. I have never had to put a charger on my bike since I got it running in July no matter what kind of riding i do.

Ok, Jumping off and riding the bike is not a good way to charge the battery.
It will get you home in an emergency (so will push starting) but the charging system is designed to keep a good battery with a full charge topped up, not restore a low battery to full charge.
Since you mention a sidestand light, I will assume you have a second generation Rebel between '96 and 2000. If its the original battery, its useful life may be over.
After running low a few times, even a new battery could die a quick death.
A new battery will run between $35 and $90 depending on what you want.
The low end would be a BikeMaster flooded cell lead acid and the higher gets in to the Yuasa AGM batteries.
Installation is straight forward. Pull the side cover, pull the battery holder. Take the ground cable off (should be a 10mm wrench) take the positive cable off, pull the vent tube off the side.
Installation is the reverse.

Rebel's Charging System.

stepcg6,

Something to Always Remember.

If the Battery won't Start the Rebel's Engine.

The Rebel's Charging System won't Recharge the Battery.


Learned from a Life Lesson. Been there, done that.

Just because the battery runs lights, does not mean it can spin the starter.
The amperage draw between lights and starter motor is enormous. Your battery charges just enough to get things going, but just barely. After removing the charger, the voltage rate probably drops quickly with no load on the battery whatsoever.
Your battery is just plain old.
My friend that works at Johnson Controls in the battery division told me that a battery that is dry (never had sulfuric acid added to it) will last forever. But once you add the acid to the battery, chemical reactions are occurring 24 hours a day, whether you use it or not. Even if you never used the battery since it was new, an 11 year old battery will have degraded chemically that the service life will be very short, if at all usable. All batteries have a shelf life, and just like people, the older it gets, the slower it gets.
Buy a new battery and enjoy the ride.:biggrin:

i have faced a similar thing. my bike is a 2009 model, had 2250 kms on it, but since the past 2 weeks, i only use it for practicing at low rev. today i lost the grip on the clutch, the bike stopped working, and since then i cant start it back. should i jump it? should i recharge it? should i buy a new one?

i only use the bike couple of days a week, if its battery going to die every couple of weeks, then this is a real headache

if you are not going on the high way yet, then up shift a little later then you normally would.

these are high revving motors and need to do so to charge the battery.

for instance the last few weeks i've been working close to my house. i have been riding at the high end of each gear to keep the revs high enough to charge the battery. so far so good, :)

well am now planing to jump the battery, and yeah, from now on i will upshift at later stages when am driving at low speed. thanx for the tip

Also remember they need air flow over the motor. Putting around below 20 mph is not good for anything but a lawn mower.:lol2:
