Let me explain first:
Couple of days ago I decided to do the 'boot trick' on my 2001 facelift model.
bonnet up, went to disconnect battery, then someone came up and I got chatting for 5mins or so, anyhow after they went, inside car pulled off the trim to get to the wiring, and unplugged the plug that has the wire to snip, suddenly noticed that the led on the console was flashing, in a panic I quickly snipped the wire for the boot feed, and plugged the plug back in place. All was well and till I came to start the engine, and that's where the problem starts !!.

So from here on;
everything back in place, go to start the car, it turns over very slowly like the batteries flat, so I think okay maybe to do with the immobiliser ?, do the ignition on and press the lock on the key fob, it does its lock and unlock, try again and no problem car starts, go for a drive & test the boot, all seemed well, then when to start the car later on in the day, and goes back to slow turn over initially, then try again, and starts normally. :-/
However, on the way to work this morning, key in ignition, turn, and very very slow and sluggish like the battery is flat.
Phone RAC, they come out & jump my car off the van and no problem, do a bit of checking, and a battery check came back as my battery is need of replacement.

I've replaced the battery & I'm hoping that all is well, I haven't yet rewire just yet, case I don't need to ?.
Oh yes... by the way, my old battery which is a Genuine Vauxhall one, and the little charge dot, isn't a light green, but more of a dark green colour.
Would appreciate any help / advise as hoping I haven't gone and done untold / un-repairable damage, otherwise there's going to be a car being broken up for spares on here soon
