Hi all,
First post so go easy on me?! :-\
Had a couple of winters which have killed a battery and put it down to freezing temps whilst it's parked up for six months.
2001 M900 Dark Fuel injection
Got the meters out this spring cos I was fed up buying batteries and found a drain on the same circuit as the ECU (Pulled fuses until the drain stopped)
We're only talking a few milliamps but over six months that has to be the main cause of dead battery.
Anything common before I start going through every circuit?
MODS:
Heated grips (I know 'big girls blouse' but they were on it when I bought it, honest)
They are on a different fuse and switched via a relay. No drain from there that I can find.
Sat Nav cradle direct of the battery with it's own in-line fuse. Again no drain there
Side stand switch has been pegged closed so I can leave it running on the stand.
Other than that, bog standard.
Any help will be gratefully received by me... (but my local battery supplier won't thank you!)
The drain is the ecu.
There's nothing you can do about it. If you're leaving your bike parked for more than a month or so disconnect the battery or pull the main fuse.
Or keep it on a battery tender
you cant expect to leave a bike for 6 months and it be ok
many bikes over many years dont like leaving for long periods
a battery tender is the best thing you can buy
keep the battery topped up and when you want to use it again it goes straight away
have had a few ducatis and batteries that are not 100% charged have always had issue starting
So basically shite electrics...
Never had any such voltage leaks on my hondas over years.
Batteries lasted ages. Even on my race bikes that had no charging circuits!
Oh what a hobby it is owning a Ducati!
Well there's ya problem.

Was your Honda fuel injected? Was it equipped with an immobilizer? Your new Honda would, and would have a similar drain. As the battery drains it's freezing point raises. A discharged battery will freeze. Even with no drain a battery not in service will discharge and batteries sulphate while discharged, lowering their capacity and life.

I got 7 years out of the original battery in my 2000 M900Sie
An old carned XL250 used a couple of times a year
Road carbed NC30 used whenever the sun came out but parked all winter
A carbed race NC30 parked for a few months at a time
Fuel injected race CBR600 with no altenator
Batteries lasted ages on all four left in the same garage in the same winters...
Oh well... Guess I'll fit a mains switch to get round the Italian shortcuts

That's probably way easier than hooking up a tender :)

all of those bikes dont require the CCA that the twin does
as i said before from experience unless the battery is at 100% you will likely have issues starting
go the battery tender , you will be guarenteed starting and aside from that bike charging systems dont like actually charging
batteries rather just keeping the battery topped up
