The Tudor TA900 is made for petrol and diesel cars without automatic engine stop. The TA900 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.

## Check this before ordering the Tudor TA900

- Measure the space: the TA900 takes up 315 × 175 × 190 mm (European case size L4).
- Polarity of the TA900: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Capacity of the TA900: 90 Ah; the same as your current battery or slightly more is fine.
- The TA900 delivers 720 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the TA900 is not the right one: it needs an EFB or an AGM.

## Inside the TA900: lead-acid technology

Inside, the TA900 is classic lead-acid: liquid electrolyte and lead plates. If the TA900 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Frequently asked questions about the Tudor TA900

### Tudor TA900 or TB800?

Compared with the TA900, the Tudor TB800 has 10 Ah less and 80 A less cranking power. The TA900 cranks harder; the TB800 is only a good option if your original battery says 640 A or less. Both measure 315 × 175 × 190 mm, so they fit the same tray.

### Can the Tudor TA900 be used in a car with Start-Stop?

No. The TA900 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM; in this same size there is the Tudor TK820.

### How much does the Tudor TA900 weigh?

The TA900 weighs 19.5 kg. For reference, the Tudor TB800 (80 Ah) weighs 19 kg.

### Which battery is equivalent to the Tudor TA900?

With the same dimensions, polarity and similar capacity you have the Exide EA900, Fulmen FA900 and Deta DA900. As the TA900 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Tudor TA900?

Case size L4: 315 × 175 × 190 mm. The TA900 fits any standard L4 battery tray such as the Exide EA900.

### Which side is the positive terminal on the Tudor TA900?

The TA900 has the positive terminal on the right, looking at the battery from its long side with the terminals closest to you.

### Which charger does the Tudor TA900 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.
