## Before ordering the TA852, check this

- Measure the space: the TA852 takes up 315 × 175 × 175 mm (European case size LB4).
- The TA852 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 85 Ah; a little more is also fine.
- The TA852 delivers 800 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the TA852 is not the right one: it needs an EFB or an AGM.

## What it means that the TA852 is lead-acid

Inside, the TA852 is classic lead-acid: liquid electrolyte and lead plates. If the TA852 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Frequently asked questions about the Tudor TA852

### TA852 or TB802: which one suits me?

Compared with the TA852, the Tudor TB802 has 5 Ah less and 100 A less cranking power. The TA852 cranks harder; the TB802 is only a good option if your original battery says 700 A or less. Both measure 315 × 175 × 175 mm, so they fit the same tray.

### Tudor TA852 or TK820: what changes?

Mainly the height: the TA852 is 175 mm tall (LB4) and the Tudor TK820 190 mm (L4), with the same length and width. In capacity and cranking power, the TK820 offers 82 Ah and 800 A against 85 Ah and 800 A. Before choosing between the TA852 and the TK820, measure the free height of the battery compartment with the cover or bonnet closed.

### Can the Tudor TA852 be used in a car with Start-Stop?

No. The TA852 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 Tudor TL752.

### How much does the Tudor TA852 weigh?

18.5 kg, with 85 Ah of capacity. For reference, the Tudor TB802 (80 Ah) weighs 17.8 kg.

### Which battery is equivalent to the Tudor TA852?

With the same dimensions, polarity and similar capacity you have the Exide EA852, Varta F18 and Fulmen FA852. As the TA852 is a conventional battery, an EFB or AGM of the same size also works. Its Bosch equivalent is the Bosch S5 010, the same as for the Varta F18. Bosch is not part of our catalogue; we list it so you can compare.

### What case size is the Tudor TA852?

Case size LB4: 315 × 175 × 175 mm. The TA852 fits any standard LB4 battery tray such as the Exide EA852.

### Which side is the positive terminal on the Tudor TA852?

On the TA852, 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.
