Right for the second time in three weeks, battery has gone flat (and I mean pancake flat) over night. Checked this morning and couldn't see anything obvious (something staying switched on even if the keys weren't in). She had the journies to and from work both Tues and Wed, so I'm a bit flumoxed. I've got her on the optimiser, but have a sneaky suspicion I may need a new battery?
Any thoughts, suggestions (polite and clean) and ideas.

She is 2008 model and I have had her two years, orig battery as I understood it. She was fine this evening after a day on the optimiser. Only thing I have extra is the alarm. I have given her a quick once over and cant see anything like wires etc. Will have a better look at weekend.
Looks like new battery (sigh). Thanks guys and to everyone who pm'd
TBH if the battery's four years old then it'll be getting towards the end of its life. Might possibly be your charging circuit has gone belly up, in which case a quick check with a voltmeter across the terminals when the engine is running should show it up (should be about 14.5 volts) but frankly I doubt it. A proper battery shop - Google one, or try your local Yellow Pages - will be able to check it out, but I'll bet my last penny it's simply a case of it giving up the ghost.
99% certain it's just needing a new battery. They very slowly lose their ability to hold a charge, and as most are sealed these days you can't do anything except fit a new one.
I don't use an optimate and have never had a problem with batteries, My Harley only gets used every other weekend and even with the alarm system it never fails to start first time. I've had the bike seven years and still on the same battery. I know a lot of people who use optimates and have had issues with their batteries...
you defo need a new battery your supposed to change them every 2 years ( all electrical goods normally last for 1000 charges ) approx. 2 yrs lol Kawasaki pull a lot of amps at start up hope it helps :)
