## Description

## Who the Tudor TB320 is for

The Tudor TB320 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 32 Ah battery, the TB320 is a direct replacement.
At 32 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The TB320 belongs to the Tudor TUDOR TECHNICA range. [The full range of Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## Inside the TB320: lead-acid technology

The TB320 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the TB320 needs no special registration: just connect it.

## Before ordering the TB320, check this

- If your car has Start-Stop, the TB320 is not the right one: it needs an EFB or an AGM.
- The TB320 delivers 270 A cold cranking (EN standard); do not go below what your original battery states.
- Your current battery should say about 32 Ah; a little more is also fine.
- Polarity of the TB320: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the TB320 takes up 178 × 135 × 225 mm.

## Frequently asked questions about the Tudor TB320

### TB320 or TB356: which one suits me?

Compared with the TB320, the Tudor TB356 has 3 Ah more and 30 A less cranking power. The TB320 cranks harder; the TB356 is only a good option if your original battery says 240 A or less. Mind the space: the TB356 measures 187 × 127 × 220 mm.

### Can the Tudor TB320 be used in a car with Start-Stop?

No. The TB320 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Tudor TB320 weigh?

9.6 kg, with 32 Ah of capacity. For reference, the Tudor TB356 (35 Ah) weighs 8.9 kg.

### Which battery is equivalent to the Tudor TB320?

With the same dimensions, polarity and similar capacity you have the Exide EB320 and Fulmen FB320. As the TB320 is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Tudor TB320?

On the TB320, 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.

### 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.
