## Inside the TA456: lead-acid technology

Inside, the TA456 is classic lead-acid: liquid electrolyte and lead plates. If the TA456 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## What to look at before buying the TA456

- If your car has Start-Stop, the TA456 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 390 A or less, the TA456 covers your engine.
- With 45 Ah, the TA456 replaces an original battery of that capacity or slightly less.
- With the terminals facing you, the positive terminal of the TA456 is on the right.
- Length, width and height of the TA456: 237 × 127 × 227 mm (European case size B24).

## Frequently asked questions about the Tudor TA456

### TA456 or TB454: which one suits me?

Compared with the TA456, the Tudor TB454 has 60 A less cranking power. The TA456 cranks harder; the TB454 is only a good option if your original battery says 330 A or less. Both measure 237 × 127 × 227 mm, so they fit the same tray.

### Can the Tudor TA456 be used in a car with Start-Stop?

No. The TA456 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Tudor TA456 weigh?

11.8 kg, with 45 Ah of capacity. For reference, the Tudor TB454 (45 Ah) weighs 11.4 kg.

### Which battery is equivalent to the Tudor TA456?

With the same dimensions, polarity and similar capacity you have the Exide EA456, Fulmen FA456 and Deta DA456. As the TA456 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TA456?

Case size B24: 237 × 127 × 227 mm. The TA456 fits any standard B24 battery tray such as the Exide EA456.

### Which side is the positive terminal on the Tudor TA456?

On the TA456, 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.

### Which charger does the Tudor TA456 need?

An automatic lead-acid charger with cut-off or maintenance mode, rated at 10 to 20% of its capacity in amps. If it is a vented type, check the electrolyte level and top up only with distilled water.
