Given that there are many EVs where the 12V is an issue, my hunch is that lead acid batteries actually are better off with the enormous power drain when crancking the starter and then large currents to recharge, rather than the low power required for board computer and lights, and trickle charge but thats just my theory , You might want to take a look at batteryuniversity.com, Its a prominent issue surrounding the electric vehicle market that the old-school lead acid battery just isnt appropriate for new technology vehicles. Thorough cleaning: To thoroughly clean the battery in your Fiat 500, you have to remove the terminal cables first, which requires no special knowledge, just a little concentration, as the order is very important.

The reading should be at or very close to zero ohms. Corrosion occurs when the battery acid reacts with the metal terminals which can lead to loss of contact and reduced current flow. This workaround is effective when the parts inside the starter are stuck together or the gears are slightly out of alignment. out what it is. I took the car to the mechanic and indeed it was a bad starter,
