Battery Draining Issue

Something is killing your battery, maybe the charging system needs to be checked. I usually get 3-4 years from original battery. If you are near a Batteries Plus store they warranty their batteries for 2 years Duracell brand.

I'd recommend you get one of these:

Amazon.com

It's a pretty cool tool that you just leave connected to your battery on the bike and an app on your phone monitors the battery over time. It'll tell you how quickly the battery is decaying and can tell you if your charging system is working correctly when the bike is running. I agree with the previous posts though that your battery is definitely not in good shape right now. Perhaps it's possible to recover it, but anything below 12.0V is by definition a completely dead battery. Do you have a battery charger you can hook up to your battery to try and charge it off the bike?

So I finally got multimeter ;-)
Charged battery 11.3V , when connected to the bike went down to 4.3V - is that normal?
And a bike would not start, not even hazard lights.
Disconnected straight away and battery was showing 10V.
No idea what does it mean

NO, NOT AT ALL. 12.5 is a over 50% drained aka dead battery, 12.6 is unhealthy, 13.1 is new, 12.85 to 12.9 is normal for a healthy battery. REGUARDLESS of being hooked up. 10.9 volts ish when cranking.
that battery is a paperweight. trash it.
AMAZING when you have a tool how you can figure things out now!
