The Exide EC400: Classic range and conventional lead-acid technology

The Classic is the Exide range the EC400 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

How to make it last longer

A classic car often stands for long spells: a trickle charger connected in the garage is the best investment for the battery. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Official warranty

The Exide EC400 comes with the manufacturer's official warranty against manufacturing defects. The warranty does not cover deep discharge through inactivity: in a classic, a trickle charger is the best protection.
