## Quick description

## Description

## Who the Tudor TC400 is for

The Tudor TC400 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. If your car has no Start-Stop and had a 40 Ah battery, the TC400 is a direct replacement.
At 40 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The TC400 belongs to the Tudor TUDOR Standard range. [The full range of Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## Tudor TC400 vs TB440 and TC440: which one to choose?

Torn between the TC400 and another similar Tudor? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Tudor TC400 (this one) | 40 Ah | 320 A | 175 × 175 × 190 | right | 10.4 kg |
| Tudor TB440 | 44 Ah | 400 A | 175 × 175 × 190 | right | 10.7 kg |
| Tudor TC440 | 44 Ah | 360 A | 207 × 175 × 190 | right | 11 kg |

- Tudor TB440: 4 Ah more, 80 A more cranking power, the same L0 case.
- Tudor TC440: 4 Ah more, 40 A more cranking power, a different case (207 × 175 × 190 mm).

## Check this before ordering the Tudor TC400

- The TC400 needs 175 × 175 × 190 mm of space (European case size L0): measure it with the hold-down clamp in place.
- With the terminals facing you, the positive terminal of the TC400 is on the right.
- Capacity of the TC400: 40 Ah; the same as your current battery or slightly more is fine.
- The TC400 delivers 320 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the TC400 is not the right one: it needs an EFB or an AGM.

## Lead-acid technology in the TC400

The TC400 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the TC400 needs no special registration: just connect it.

## Frequently asked questions about the Tudor TC400

### TC400 or TB440: which one suits me?

Compared with the TC400, the Tudor TB440 has 4 Ah more and 80 A more cranking power. If your current battery says 400 A or more, choose the TB440; if it says 320 A or less, the TC400 is enough. Both measure 175 × 175 × 190 mm, so they fit the same tray.

### Can the Tudor TC400 be used in a car with Start-Stop?

No. The TC400 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Tudor TC400 weigh?

10.4 kg, with 40 Ah of capacity. For reference, the Tudor TB440 (44 Ah) weighs 10.7 kg.

### Which battery is equivalent to the Tudor TC400?

With the same dimensions, polarity and similar capacity you have the Exide EC400, Fulmen FC400 and Deta DC400. As the TC400 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TC400?

Case size L0: 175 × 175 × 190 mm. The TC400 fits any standard L0 battery tray such as the Exide EC400.

### Which side is the positive terminal on the Tudor TC400?

On the TC400, 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.
