Fiat 500 stop/start battery replacement

[LHRFlightman]

Is this something I can replace on my daughter's car? Halfords want to change over £100 to replace the damn battery.

Thanks

They want £100 to supply and fit or £100 to fit .... The battery will either be an EFB or AGM battery and will be around £100 alone. Bosch or Varta, preferably Varta are what you should aim for.
