Is my battery dying? Weird 'won't start' event...

Hey folks! I was out riding on Sunday doing something that involves a lot of stops and starts (Ingress if anyone knows it, if you don't, dont' worry about it). At one stop, I was idling for perhaps 3 minutes, and went to move off... now, my bike stalls easily - I chalk this to "I rode a big heavy 4 cylinder bike for ages, these tighter 2 cylinder engines are not as forgiving". The stalls usually are "one cylinder fires, then the 'fwee' sound of a miss, and it stops".

A quick buttonpush and I'm usually on my way again (I've done this rolling into intersections even).

This time,however, there was a very weak turnover, and my instrument panel reset (gauges rolled right and left, clock reset to 1:00).

After checking over everything and trying a whole combination of things, I had to admit "This is behaving like the battery is dead.". I rolled the bike up a little incline, down again and popped it in third gear, and it started right up.

After I rode home (being careful to avoid a stall), I shut it down outside the carpark, and started it again. Ticked over perfectly! No problem. I've started it 3 times since then, and every time, no battery or "slow turnover" problem, it's a perfect "hit the power, get the fuel pump whine, push start, it starts right up" sequence.

Talking with a friend who has experience with the Stroms, he points out that they start acting twitchy when the battery is on it's way out. Before I drop bucks on a replacement battery, I call to the wisdom of the Troopers. Is this an indication of a dying battery?

I have no electronics on the bike that are not self-powered, so there was no random drain going on.

Thanks!

Those are low power signs. A marginal battery or cable connection are the things to check.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I have moved my battery connection once, but that was weeks and weeks ago, and it's secure and strong (I checked that). Got a suggestion on the best way to get a battery tested? Is this just Joe Bob's garage and use a battery tester? Ohh, wait, there's a Batteries Plus down the street, I can probably have them do it. Hmmm!

Check your voltage over 13.4 at 3000 rpm

Update...

So on Sunday I hauled the battery out of the Wee and took it to the local Batteries+. These guys have been super-helpful in the past. They tested it on two different battery testers, and both showed an output of 11v (should be 13.5, looks like a dead cell).

Low voltage is a sure indicator of a blown battery, so I replaced it. Things have been running perfectly since.

Thanks for everyone's feedback!
