Flat as a pancake after 12 days

[the dodger]

I've left my car for two weeks before without connecting the trickle charge - several times. If it's going to be more then I plug it in and over the winter usually fire it up a few times as well. I last used it on Bank Hol Monday but yesterday when I turned the key NOTHING! - not even any warning lights on first position! Car in (narrow) garage battery-side hard against the wall so I thought I'd plug in the Draper 300mA charger - and wait. Lots of clicking going on around the door-locks then ZAP! the central locking energised and locked me out! Early Chim with key locks so I thought no problem. Was it ! - Key operation failed, still couldn't get in.

Fortunately as car in secure garage the roof was off so I could reach in and twist the door opener but I wondered - Is there another way in for this situation?

Left charger on overnight and today the key operation worked! (just) and door now unlocked. Strange that when the battery voltage dropped the alarm didn't go off???

Anyway, any ideas why the battery flattened itself? New siren fitted a few weeks ago but other than that, no changes.

had exactly the same thing happen to me yesterday. 2 weeks on hols and got back to find flat as a pancake and had to get in via another method as my roof was up. will be plugging in the trickle charger for anything more than a couple of days me thinks next time. have mailed you method i got in.

Used to own a Griff 500 that suffered from this.It used to flatten battery overnight,even after a good run!
It was found that the wiring loom was shorting out in 2 places,the ice warning light circuit,and the headlight circuit.It needed a new loom fitted.These 'shorts' seemed to occur after I had to have the car jump-started by the RAC.

...Was wondering the exact same thing myself .
I went away for 3 weeks and havent left it for any length of time before. Id never got round to ordering a trickle charger and so had to decide whether to leave a window open or roof down so I could get back in. Eventually decided to leave the window open expecting it to be as flat as a witch's t*t on my return but luckily she fired up without a problem .
