Dead batteries SUCK

Welp my evening ride went to ****. My bike died at a light and wouldn't start back. Get my pop to come jump it and get it home n check it n its charging. AT idle its putting bout 12.3-5 out. Rev it n hold and it jumps to 14. SO I dont get it less the battery is toast. It has been doing good, tho I don't know how old it is. other than the battery being of shot, anyone have any suggestion on what to check?

Cuz the thought of not riding SUX!

batteries are cheap.. from experience, once a battery has completely drained, the plates sometimes gets damaged (shorted) and will not last another year.

Once the battery is charged up and good.

Let the bike and battery sit for about 1 -2 days. Then check to see if its holding that charge. Should show 12.8 volts or so. Just sitting with the bike and key off. If not.. most likely the battery is toast.

If you have a service manual it would tell you how to check the VR (Voltage regulator). Usually all it requires is disconnecting the VR from the stator system and checking ohlms. However... you already said that the stator was putting out the right amount of voltage with the idle up. If the VR was bad that wouldn't be happening.

Understand that the VR converts the AC voltage from the stator to DC voltage for your bike.

Question, on a car you can take the battery cable loose n see if the car stays running if the charging system is good. Does this hold true for motorcycles as well?

OK I waited until just a bit ago (sat all day yesterday, rain) to check the battery's voltage, it was at 12.5v and starts fine, and shows its charging when checked with a multimeter. Any clues?

Well there are only 3 parts to the charging system... battery, stator, VR... 85% of the time the battery is always the weak and most wearable link. 12.5 is a bit low... should be 12.8+

You can try the disconnect the battery. but if you're getting high voltage shown on the battery with the bike running and idle up then its most likely good.

I have a trickle charger for motorcycle batteries which charges in about 6 hours. In a pinch however, I've used my ride lawnmower to jump it at the start of the season.

If you or a neighbor have a ride lawnmower, hopefully it will have the battery right under the seat which will allow you to run jumpers from your bikes battery right to the mower. Of course you need to keep the mower running at medium to full throttle while jumping, just like a car.

The leads on such small batteries are pretty tiny so you my have to hold the cables on each post.

Beats buying a new one for a couple weeks though

Hope this helps.

Actually you don't want to jump start a bike with a RUNNING car. Too much amperage! A mower... idk.

I don't get it... The system should not source more than it needs unless there's a short... Even then, a decent car battery can source a kiloamp if shorted...

No the charging system on the car. When the car is running the car's alternator puts out X # of power to the car's battery. But when you piggy back your small bike battery to it with jumper cables. The amount of power from the car's alternator is a bit much for the small bike battery. Same theory as to why you only charge a bike battery on 2amps or less. They are just to small and can't take any more than that.

Further you could probably start 10 bikes off one car battery!

Thankfully all has went well since I let the battery charge over night off a 2amp trickle charger. Been riding since sunday with no problems, and lord willing it will continue lol.

Bad news, battery died again. Worked fine all day, was hooking up a led tag light n turn the key on to see if it worked. Switch was on long enuff to turn it on n step back n look at the tag light and back n hit the starter.. click click.

So any recommendations on what brand of battery to get?

What are the dimensions on your battery? I have a brand new non-spillable battery in my garage. It has about 40 miles on it. About 3 weeks old and has been on the battery tender. Got it thru a warrenty on the big dog but don't need it. I'd sell it to you for cheap if it will fit...
