Heat does most of the damage. Months of high under-bonnet temperatures, short hops along Jumeirah Beach Road and long spells parked outside wear a Fiat battery down faster than it would in a cooler climate, and the weakness tends to show up in summer.
Fiat models take compact batteries that are quick to replace. Versions with Start&Stop need an EFB or AGM battery.
We regularly replace batteries in the 500, 500X, Tipo, and Doblo. Whichever Fiat you drive, the technician tests the old battery first, confirms the correct size and type for your car, then fits and checks the new one while you watch.
