## Quick description

The Tudor TB454 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. With the positive terminal on the left, the exact counterpart is the Tudor TB455.

## Description

## Who the Tudor TB454 is for

The Tudor TB454 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 TB454 belongs to the Tudor TUDOR TECHNICA range. [See all Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

Torn between the TB454 and another similar Tudor? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Tudor TB454 (this one) | 45 Ah | 330 A | 237 × 127 × 227 | right | 11.4 kg |

The TB454 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the TB454 needs no special registration: just connect it.

## Before ordering the TB454, check this

- If your car has Start-Stop, the TB454 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 330 A or less, the TB454 covers your engine.
- Capacity of the TB454: 45 Ah; the same as your current battery or slightly more is fine.
- With the terminals facing you, the positive terminal of the TB454 is on the right.
- The TB454 needs 237 × 127 × 227 mm of space (European case size B24): measure it with the hold-down clamp in place.
