Who the Exide EL550 is for

The Exide EL550 is designed for automatic engine stop and regenerative braking. In a Start-Stop car, the EL550 keeps the radio, climate control and lights running with the engine off without losing capacity.

At 55 Ah it covers petrol compacts and small diesels, the best-selling format in Europe. The EL550 belongs to the Exide EXIDE EFB range. More Exide batteries

Inside the EL550: EFB technology

Inside, the EL550 uses EFB technology, a reinforced version of the flooded battery. The EL550 works with normal chargers that have a lead-acid or EFB mode.

What to look at before buying the EL550

  • The EL550 is an EFB: it suits cars that had an EFB or a conventional battery. If yours had an AGM, fit another AGM.
  • The EL550 delivers 540 A cold cranking (EN standard); do not go below what your original battery states.
  • With 55 Ah, the EL550 replaces an original battery of that capacity or slightly less.
  • Polarity of the EL550: positive terminal on the right (if yours has it on the other side, the cables will not reach).
  • Measure the space: the EL550 takes up 207 × 175 × 190 mm (European case size L1).

Frequently asked questions about the Exide EL550

EL550 or EL600: which one suits me?

Compared with the EL550, the Exide EL600 has 5 Ah more and 100 A more cranking power. If your current battery says 640 A or more, choose the EL600; if it says 540 A or less, the EL550 is enough. Mind the space: the EL600 measures 242 × 175 × 190 mm.

Can the Exide EL550 be used in a car with Start-Stop?

Yes, the EL550 is an EFB: it suits Start-Stop without brake energy recovery, or cars that already had an EFB. If your car left the factory with an AGM, fit another AGM.

How much does the Exide EL550 weigh?

14.1 kg, with 55 Ah of capacity. For reference, the Exide EL600 (60 Ah) weighs 17.5 kg.

Which battery is equivalent to the Exide EL550?

In EFB or AGM, with its dimensions and polarity: Tudor TL550 and Fulmen FL550. A conventional battery does not replace the EL550.

What case size is the Exide EL550?

Case size L1: 207 × 175 × 190 mm. The EL550 fits any standard L1 battery tray such as the Tudor TL550.

Which side is the positive terminal on the Exide EL550?

On the EL550, the positive terminal is on the right with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

Why does a Start-Stop battery cost more than a standard one?

Because it uses reinforced plates and separators to withstand thousands of starts and partial discharges. A conventional battery in a Start-Stop car can fail in under a year.
