The Tudor TB800 is made for petrol and diesel cars without automatic engine stop. If your car has no Start-Stop and had a 80 Ah battery, the TB800 is a direct replacement.
At 80 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The TB800 belongs to the Tudor TUDOR TECHNICA range. [The full range of Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## Tudor TB800 vs TL800, TB802 and TK820: differences

How the TB800 compares with Tudor batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Tudor TB800 (this one) | 80 Ah | 640 A | 315 × 175 × 190 | right | 19 kg |
| Tudor TL800 | 80 Ah | 800 A | 315 × 175 × 190 | right | 22.1 kg |
| Tudor TB802 | 80 Ah | 700 A | 315 × 175 × 175 | right | 17.8 kg |
| Tudor TK820 | 82 Ah | 800 A | 315 × 175 × 190 | right | 23.3 kg |

- Tudor TL800: the same capacity, 160 A more cranking power, the same L4 case, EFB technology.
- Tudor TB802: the same capacity, 60 A more cranking power, a different height (175 mm instead of 190 mm, LB4). It is the option if your battery tray cannot take the 190 mm height of the TB800.
- Tudor TK820: 2 Ah more, 160 A more cranking power, the same L4 case, AGM technology.

## Equivalents and alternatives to the Tudor TB800

Batteries that fit the TB800's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the TB800.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Exide EB800 | Lead-acid | 80 Ah | 640 A | 315 × 175 × 190 |
| Fulmen FB800 | Lead-acid | 80 Ah | 640 A | 315 × 175 × 190 |
| Deta DB800 | Lead-acid | 80 Ah | 640 A | 315 × 175 × 190 |
| Varta F16 | Lead-acid | 80 Ah | 740 A | 315 × 175 × 190 |
| Kronobat PB-80.0 | Lead-acid | 80 Ah | 740 A | 315 × 175 × 190 |

## Lead-acid technology in the TB800

Inside, the TB800 is classic lead-acid: liquid electrolyte and lead plates. If the TB800 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Check this before ordering the Tudor TB800

- If your car has Start-Stop, the TB800 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 640 A or less, the TB800 covers your engine.
- With 80 Ah, the TB800 replaces an original battery of that capacity or slightly less.
- Polarity of the TB800: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Length, width and height of the TB800: 315 × 175 × 190 mm (European case size L4).

## Frequently asked questions about the Tudor TB800

### TB800 or TL800: which one suits me?

Compared with the TB800, the Tudor TL800 has 160 A more cranking power and EFB technology. If your current battery says 800 A or more, choose the TL800; if it says 640 A or less, the TB800 is enough. Both measure 315 × 175 × 190 mm, so they fit the same tray.

### Tudor TB800 or TB802: what changes?

Mainly the height: the TB800 is 190 mm tall (L4) and the Tudor TB802 175 mm (LB4), with the same length and width. In capacity and cranking power, the TB802 offers 80 Ah and 700 A against 80 Ah and 640 A. Before choosing between the TB800 and the TB802, measure the free height of the battery compartment with the cover or bonnet closed.

### Can the Tudor TB800 be used in a car with Start-Stop?

No. The TB800 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 TL800.

### How much does the Tudor TB800 weigh?

19 kg, with 80 Ah of capacity. For reference, the Tudor TL800 (80 Ah) weighs 22.1 kg.

### Which battery is equivalent to the Tudor TB800?

With the same dimensions, polarity and similar capacity you have the Exide EB800, Fulmen FB800 and Deta DB800. As the TB800 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TB800?

Case size L4: 315 × 175 × 190 mm. The TB800 fits any standard L4 battery tray such as the Exide EB800.

### Which side is the positive terminal on the Tudor TB800?

On the TB800, 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.
