long term battery disconnection ( non Seat)

[shaunw]

My Dads had a stroke and he wants me to prepare his car for storage in his garage; get it up on blocks, drain the fuel etc.

My question is what (if any) effect long term disconnection of the battery may have on the cars electrical systems (ECU, bluetooth, etc). I'm not sure if any of these systems use backup batteries and if they do, how long they are designed to last without power from the main battery.

Can anybody enlighten me?

Cheers

Shaun

i would imagine that there isnt realli any problem, just as long you have all the codes etc for your headunits and stuff! i think most electrical products will store any info onto ROM and hence will still be there when you turn the power back on!

thats what i think anyhows!

Vauxhall's will lose some of the setting in the ECU. Although this isn't a bad thing as it will force it to relearn the driving style, some people do this on purpose.
What car is it?
Have you considered a trickle charger? Obviously disconnecting the battery is cheaper!

what car is it? commonly its not worth storing a modern common car, as it will depreciate, its better to sell and buy another one when you come to needing it again. Depends how long the storage is for as well, the longer it is the more suitable it is to sell.

Cheers for the replies guys.

The car is a Citreon C4.

Dad wont entertain selling it as it was it was his first brand new car and is only just a year old. He paid a fortune to have leather seats, sat nav, glass roof etc. He also bought an automatic as he realised he wasnt getting any youger and wanted something that was as easy to drive as possible.

The other problem with selling is it is that we have no idea how long it will take him to recover. it could be as short as 6 months or maybe never. God willing doctors tell us, he could be back driving within a year.

Trickle charger could be an idea, hadn't thought of that.

thanks again

prob'ly the best bet Halford's and CTEK came out best in last weeks Auto Express tests as they have pulse conditioning, and can be left connected, a service before storage might be a good plan also, hope it all goes well

yeah, everyone seems to do it when theyve had mods put on.

they say to disconnect for 30+ mins and then drive normally after, the ecu settings will be re learnt and hence possibly a smoother, better drive
