What Exide does differently

Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Exide EG1203: Start PRO range and conventional lead-acid technology

The EG1203 is part of the Exide Start PRO range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

Usage and maintenance tips

During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing.

Warranty and coverage

The Exide EG1203 comes with the manufacturer's official warranty against manufacturing defects. An important note for commercial vehicles: most trucks use two batteries connected in series (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace both at the same time.
