Are Stop Start batteries more expensive?

Yet, special batteries are also required for cars equipped with Stop-Start, which are, unsurprisingly, more expensive and more powerful than contemporary standard types. However, if cars with Stop-Start capability are not fitted with the correct replacement batteries, the electrical system can be damaged.

How long do stop/start batteries last?

How long so start stop batteries last? While the majority of regular LSI batteries are generally guaranteed to last around four years, they can in fact go on to last up to six or seven years.

Why is stop/start not working?
