Charging Voltage

I have a 2008 TE510 that has killed two batterys. They die in the middle of a ride the bike starts to spuder a few times then just dies and the battery has less than 2v. I put a new battery in and checked the charging volts its 14.5 at idle my new Beta is at 13.1. is 14.5 normal or is this why my batterys die an untimely death by overchargeing

14.5 is not too high, Make sure all your grounds are solid and tight, especially the big one from the battery.

A fully charged battery should be north of 12.75 volts with the engine off. During charging via the stator it should be circa 14 volts or a tad higher,
If your bike is discharging a new battery so soon it can only be a short. Follow your leads and look for shorting out propects

it will go a year without an issue sit for months start fine ect. Then all of a suden doing a ride just quit and the battery will not take a charge its that dead I cant belive that a short would just kill the battery and not blow a fuse or something.

It does sound strange SoKal but it must be a major and sudden discharge to kill a battery that way. Sounds like the battery leads are the culprit as a first guess.

You are using AGM batteries and not Lead-Acid right? Just a thought.

Also would be worthwhile to check for any loose connections or corrosion on the stator plugs. Maybe the stator stops charging and kills down the battery. The main plug is round with 3 yellow wires and comes up off the stator and plugs up under the tank on the left hand side of the bike. Make sure no chaffing or anything.

Yes using AGM

If it's 14.5 at idle what is it at 5,000rpm ?

14.5 at idle is excellent-what is your idle at anyway-might be a tad high. I think 14.5 is pretty toppy.
