Gs500 is draining my new battery

[broken26]

I checked the resistance on the positive cable and negative cable. Not entirely sure what reading I should be getting but at the lowest ohms resistance i'm getting infinite throughout most of the dials. At the highest 20M I'm getting 8.04ish resistance reading.

8M ohms is a lot. You'd only be drawing 1.5 micro-amps of current when it's off, so that isn't the problem.

In that case I'd agree you probably have a bad battery Sorry for the diversion.

Thanks for the help and reply. Just last note before I attempt to get my warranty to get a replacement battery. How would a battery be "bad" if the batteries plus people tell me because it passed the load test its good?

Is it no longer holding a full charge because build-up gunk ruining the battery while riding 2 weeks on low fluid levels? Or would a loadtest just not test for that. I don't really know what a load test means in regards to battery health.

If it were me I'd just tell them, "I don't know what the load test does but it doesn't work to start the motorcycle. I'd like to exchange it for one that will start the motorcycle" ... just play dumb and insist that a good battery should work to start the motorcycle after sitting overnight so this one must not be good, right?

You can google "why lead acid battery won't hold charge" just as well as I can, and the information you get there will be at least as good as what I would tell you. If you really want to know, then go for it. But they should replace the battery for you based on its actual performance in the intended application.

It doesn't really matter that the voltage reads 13.1 right after charging, for a flooded battery it should be 2.6 - 2.7 after it has been sitting for at least 4 hours. A good AGM battery will be anywhere from 12.8 to 13.1, your 12.2 reading would indicate that the battery is faulty that's only about a 40% charge. If it's three weeks old then the battery was faulty when you got it. Batteries don't lose enough water to get damaged in three weeks that is ridiculous. FFIW my flooded battery which is at least a few years old and has had the level drop down below the plates a few times, still reads 2.3V after standing overnight and still cranks the engine instantly.

It's an Xtreme xt9l-b 12v 9aH battery I got from batteries plus.

I'd like to add that even the 11Ah batteries are often marginal in the GS5.
I would ask for an exchange: pay just the price difference and get at least an 11Ah battery.
Even better, an AGM (Motobatt makes a 14Ah one in our size I think, MB10U).
