5 air-bag faults vs new battery???

Hello. There have been several posts about air-bag lights, but I can't find any threads mentioning a connection between a dodgy battery and air-bag faults. I see the sticky thread at the top, but that does not relate to air-bag problems. Here's the thing, as brief as possible:

Alfa 156 SW, yr 2000. 5 air-bag faults. 2 different people have reset the light, but the errors come back immediately. I haven't got the list with me, but it is something like:
passenger side bag squib fault.
driver side bag squib.
passenger squib.
Something about ECU low voltage.
air-bag ECU faulty.

Local garage reckons I have a wiring fault, and a specialist car electrician said he didn't want to touch it in case air-bags started going off.

Simple question: Do you reckon I should buy a new battery, and try resetting the light again before getting someone expensive to have a go at it ......No it answers itself. I am going to spend the dosh on a new battery, and a bit more money on a reset, unless anyone thinks it's a stupid idea.

Stupid or not? Is there any chance that I could cure the air-bag faults with a new battery? ...and if I paint it, will that stop the suspension squeak at the back ...
(The battery goes flat if the car is left unused for 2 weeks, but gut-feeling says this may be a wiring fault rather than the battery).

Remove old battery, after 15-30 minutes clean and reseat all airbag leads particularly those to ecu and under seats. Fit new battery and reset airbag lights.

btw remember you will need the code if it's the original stereo setup.

Good luck.
