## Who the Tudor TA640 is for

The Tudor TA640 is made for petrol and diesel cars without automatic engine stop. The TA640 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.

What sets the TA640 apart from its neighbours in the Tudor range:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Tudor TA640 (this one) | 64 Ah | 640 A | 242 × 175 × 190 | right | 14.9 kg |

- Tudor TA612: 3 Ah less, 40 A less cranking power, a different height (175 mm instead of 190 mm, LB2). It is the option if your battery tray cannot take the 190 mm height of the TA640.
- Tudor TK620: 2 Ah less, 40 A more cranking power, the same L2 case, AGM technology.

## Equivalents and alternatives to the Tudor TA640

Batteries that fit the TA640's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the TA640.

|---|---|---|---|---|
| Exide EA640 | Lead-acid | 64 Ah | 640 A | 242 × 175 × 190 |

## Inside the TA640: lead-acid technology

Inside, the TA640 is classic lead-acid: liquid electrolyte and lead plates. If the TA640 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Before ordering the TA640, check this

- If your car has Start-Stop, the TA640 is not the right one: it needs an EFB or an AGM.
- The TA640 delivers 640 A cold cranking (EN standard); do not go below what your original battery states.
- Capacity of the TA640: 64 Ah; the same as your current battery or slightly more is fine.
- The TA640 has the positive terminal on the right: compare it with your current battery.
- Measure the space: the TA640 takes up 242 × 175 × 190 mm (European case size L2).

## Frequently asked questions about the Tudor TA640

### TA640 or TB620: which one suits me?

Compared with the TA640, the Tudor TB620 has 2 Ah less and 100 A less cranking power. The TA640 cranks harder; the TB620 is only a good option if your original battery says 540 A or less. Both measure 242 × 175 × 190 mm, so they fit the same tray.

### Tudor TA640 or TA612: what changes?

Mainly the height: the TA640 is 190 mm tall (L2) and the Tudor TA612 175 mm (LB2), with the same length and width. In capacity and cranking power, the TA612 offers 61 Ah and 600 A against 64 Ah and 640 A. Before choosing between the TA640 and the TA612, measure the free height of the battery compartment with the cover or bonnet closed.

### Can the Tudor TA640 be used in a car with Start-Stop?

No. The TA640 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM; in this same size there is the Exide EK620.

### How much does the Tudor TA640 weigh?

14.9 kg, with 64 Ah of capacity. For reference, the Tudor TB620 (62 Ah) weighs 13.9 kg.

### Which battery is equivalent to the Tudor TA640?

With the same dimensions, polarity and similar capacity you have the Exide EA640, Fulmen FA640 and Deta DA640. As the TA640 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TA640?

Case size L2: 242 × 175 × 190 mm. The TA640 fits any standard L2 battery tray such as the Exide EA640.

### Which side is the positive terminal on the Tudor TA640?

On the TA640, 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.
