Idle vehicles around the UK as a result of Coronavirus lockdown measures introduced in late March could lead to considerable damage to car batteries. In-vehicle electrical systems and alarms drain the battery continually, alongside the natural loss in charge. These factors could result in significant numbers of batteries requiring recharging or replacement in the coming months. Aftermarket supplier The Parts Alliance is encouraging garages to offer a battery testing service to their customers proactively. The company has produced a range of marketing materials to help promote such an offering.
