## The Exide EC900 at a glance

The Exide EC900 is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. The EC900 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 90 Ah it moves into large diesels, SUVs, vans and cars with heavy electrical equipment. The EC900 belongs to the Exide EXIDE CLASSIC range. [See all Exide batteries](https://bateriasonline.es/en/exide-batteries)

## What it means that the EC900 is lead-acid

The EC900 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.

## What to look at before buying the EC900

- If your car has Start-Stop, the EC900 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 720 A or less, the EC900 covers your engine.
- Your current battery should say about 90 Ah; a little more is also fine.
- The EC900 has the positive terminal on the right: compare it with your current battery.
- The EC900 needs 353 × 175 × 190 mm of space (European case size L5): measure it with the hold-down clamp in place.
