## Lead-acid technology in the TB440

Inside, the TB440 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## What to look at before buying the TB440

- If your car has Start-Stop, the TB440 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 400 A or less, the TB440 covers your engine.
- With 44 Ah, the TB440 replaces an original battery of that capacity or slightly less.
- With the terminals facing you, the positive terminal of the TB440 is on the right.
- The TB440 needs 175 × 175 × 190 mm of space (European case size L0): measure it with the hold-down clamp in place.

## Frequently asked questions about the Tudor TB440

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

Compared with the TB440, the Tudor TC400 has 4 Ah less and 80 A less cranking power. The TB440 cranks harder; the TC400 is only a good option if your original battery says 320 A or less. Both measure 175 × 175 × 190 mm, so they fit the same tray.

### Can the Tudor TB440 be used in a car with Start-Stop?

No. The TB440 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Tudor TB440 weigh?

10.7 kg, with 44 Ah of capacity. For reference, the Tudor TC400 (40 Ah) weighs 10.4 kg.

### Which battery is equivalent to the Tudor TB440?

With the same dimensions, polarity and similar capacity you have the Exide EB440, Fulmen FB440 and Deta DB440. As the TB440 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TB440?

Case size L0: 175 × 175 × 190 mm. The TB440 fits any standard L0 battery tray such as the Exide EB440.

### Which side is the positive terminal on the Tudor TB440?

On the TB440, 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.
