Oh Hell here we go again BLOODY BATTERY

Please Advise

After been stuck on the top of the A66 all night freezing to death due to been out of hours and having to sleep in the fookin truck again. got back to yard and got in to frozen solid old faithfull disco 1 300tdi.

Switched on ignition and awaited glowplug light to go off then motor turned over very very very slowly and finally fired up. Though hmmm should get round to that new battery I have been promisisng the old girl so went over to local bloke in order to have battery checked and lo and behold I was wrong the battery is not knackered after all more a case of previous owner has fitted a small dinky batter for a mini !!!!! amazed it starts at all. I now have a nice shiney heavy duty battery that is the correct one sitting in the back of the disco now for the question. Can I just go and swap them str8 over as I would normally do or will disconnecting the battery cause me loads of problems with the alarm/ immoboliser and if it is gonna whats the best way to go about it please

I know this has probably been covered somewhere else but I cannie find it so please forgive me and any advice offered greatly recived

oh and does n e one want a good mini battery?

As long as you're quick, you should only need to reset the radio... too long and you may need to reprogram the key fobs i would think.

I didn't even think about it when playing with my earths though so just swapping it over should be fine!

havent long done mine ,just swaped batts over
but make sure you have radio code?

Well here goes then I will just be quick and swap it fingures crossed and ta for the help

we had the batter disconected for weeks on the 300tdi disco at work no problems

All done that musta count as easiest landy job ever lolol
don't know why I was worried now I just hope the problems fixed !!!!
Ta for the help guys

If you get two cig lighter plugs on the end of two longish wires then you can plug one end in your lighter socket and the other end in someone elses socket parked close by and you wont loose your radio code.

Just need a small amount of power to the lighter socket actually to hold the code.
