## Quick description

The Tudor TB456 is a car battery with 12 V, 45 Ah and 330 A cold cranking current, case size B24 (237 × 127 × 227 mm), with the positive terminal on the right. Need the positive terminal on the left? The same battery is the Tudor TB455.

## Description

## Where the Tudor TB456 fits

The Tudor TB456 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 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The TB456 belongs to the Tudor TUDOR TECHNICA range. [See all Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## Inside the TB456: lead-acid technology

The TB456 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the TB456 needs no special registration: just connect it.

## Before ordering the TB456, check this

- If your car has Start-Stop, the TB456 is not the right one: it needs an EFB or an AGM.
- The TB456 delivers 330 A cold cranking (EN standard); do not go below what your original battery states.
- Your current battery should say about 45 Ah; a little more is also fine.
- With the terminals facing you, the positive terminal of the TB456 is on the right.
- The TB456 needs 237 × 127 × 227 mm of space (European case size B24): measure it with the hold-down clamp in place.

## Frequently asked questions about the Tudor TB456

### TB456 or TA456: which one suits me?

Compared with the TB456, the Tudor TA456 has 60 A more cranking power. If your current battery says 390 A or more, choose the TA456; if it says 330 A or less, the TB456 is enough. Both measure 237 × 127 × 227 mm, so they fit the same tray.

### Tudor TB456 or TB455: what is the difference?

Only the polarity: the TB456 has the positive terminal on the right and the TB455 the positive terminal on the left. Capacity (45 Ah), cranking power and dimensions are identical.

### Can the Tudor TB456 be used in a car with Start-Stop?

No. The TB456 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Tudor TB456 weigh?

11.3 kg, with 45 Ah of capacity. For reference, the Tudor TA456 (45 Ah) weighs 11.8 kg.

### Which battery is equivalent to the Tudor TB456?

With the same dimensions, polarity and similar capacity you have the Exide EB454, Exide EB456 and Fulmen FB454. As the TB456 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TB456?

Case size B24: 237 × 127 × 227 mm. The TB456 fits any standard B24 battery tray such as the Exide EB454.

### 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.
