## Description

## Who the Exide EA770 is for

The Exide EA770 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. Its job is to start the engine in the cold with margin to spare and keep the car's electronics powered.
At 77 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The EA770 belongs to the Exide EXIDE Premium range. [More Exide batteries](https://bateriasonline.es/en/exide-batteries)

## What it means that the EA770 is lead-acid

The EA770 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.

## Check this before ordering the Exide EA770

- If your car has Start-Stop, the EA770 is not the right one: it needs an EFB or an AGM.
- The EA770 delivers 760 A cold cranking (EN standard); do not go below what your original battery states.
- Your current battery should say about 77 Ah; a little more is also fine.
- The EA770 has the positive terminal on the right: compare it with your current battery.
- Length, width and height of the EA770: 278 × 175 × 190 mm (European case size L3).

## Frequently asked questions about the Exide EA770

### EA770 or EB740: which one suits me?

Compared with the EA770, the Exide EB740 has 3 Ah less and 80 A less cranking power. The EA770 cranks harder; the EB740 is only a good option if your original battery says 680 A or less. Both measure 278 × 175 × 190 mm, so they fit the same tray.

### Can the Exide EA770 be used in a car with Start-Stop?

No. The EA770 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Exide EA770 weigh?

17.4 kg, with 77 Ah of capacity. For reference, the Exide EB740 (74 Ah) weighs 16.6 kg.

### Which battery is equivalent to the Exide EA770?

With the same dimensions, polarity and similar capacity you have the Tudor TA770, Fulmen FA770 and Deta DA770. As the EA770 is a conventional battery, an EFB or AGM of the same size also works. Its Bosch equivalent is the Bosch S5 008, the same as for the Varta E44. Bosch is not part of our catalogue; we list it so you can compare.

### What case size is the Exide EA770?

Case size L3: 278 × 175 × 190 mm. The EA770 fits any standard L3 battery tray such as the Tudor TA770.

### Which side is the positive terminal on the Exide EA770?

On the EA770, 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.

### Does the new battery need to be registered in the car?

In cars with energy management (common since 2010) it is worth registering the battery in the control unit so it adjusts charging. In older cars you just connect it.
