## What to look at before buying the EA406

- Length, width and height of the EA406: 187 × 127 × 220 mm.
- The EA406 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 40 Ah; a little more is also fine.
- The EA406 delivers 350 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the EA406 is not the right one: it needs an EFB or an AGM.

## Lead-acid technology in the EA406

Inside, the EA406 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## Frequently asked questions about the Exide EA406

### EA406 or EA386: which one suits me?

Compared with the EA406, the Exide EA386 has 2 Ah less and 50 A less cranking power. The EA406 cranks harder; the EA386 is only a good option if your original battery says 300 A or less. Both measure 187 × 127 × 220 mm, so they fit the same tray.

### Can the Exide EA406 be used in a car with Start-Stop?

No. The EA406 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Exide EA406 weigh?

9.3 kg, with 40 Ah of capacity. For reference, the Exide EA386 (38 Ah) weighs 9.9 kg.

### Which battery is equivalent to the Exide EA406?

With the same dimensions, polarity and similar capacity you have the Tudor TA406, Fulmen FA406 and Deta DA406. As the EA406 is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Exide EA406?

On the EA406, 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.

Between 4 and 6 years in normal use. Very short trips, extreme heat and leaving the car parked for weeks without starting it shorten its life.
