Who the Tudor TA681 is for
The Tudor TA681 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. The TA681 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 68 Ah it is the usual size for compact diesels and mid-size petrol saloons. The TA681 belongs to the Tudor TUDOR HIGH TECH range. The full range of Tudor batteries

Inside the TA681: lead-acid technology
The TA681 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
Before ordering the TA681, check this
- If your car has Start-Stop, the TA681 is not the right one: it needs an EFB or an AGM.
- Cold cranking: 650 A (EN), equal to or higher than the original.
- Your current battery should say about 68 Ah; a little more is also fine.
- Polarity of the TA681: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- The TA681 needs 277 × 175 × 190 mm of space (European case size L3): measure it with the hold-down clamp in place.
Frequently asked questions about the Tudor TA681
TA681 or TB741: which one suits me?
Compared with the TA681, the Tudor TB741 has 6 Ah more and 30 A more cranking power. If your current battery says 680 A or more, choose the TB741; if it says 650 A or less, the TA681 is enough. Both measure 277 × 175 × 190 mm, so they fit the same tray.
Tudor TA681 or TA680: what is the difference?
Only the polarity: the TA681 has the positive terminal on the left and the TA680 the positive terminal on the right. Capacity (68 Ah), cranking power and dimensions are identical.
Can the Tudor TA681 be used in a car with Start-Stop?
No. The TA681 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.
How much does the Tudor TA681 weigh?
17 kg, with 68 Ah of capacity. For reference, the Tudor TB741 (74 Ah) weighs 16.6 kg.
Which battery is equivalent to the Tudor TA681?
With the same dimensions, polarity and similar capacity you have the Exide EA681. As the TA681 is a conventional battery, an EFB or AGM of the same size also works.
What case size is the Tudor TA681?
Case size L3: 277 × 175 × 190 mm. The TA681 fits any standard L3 battery tray such as the Exide EA681.
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.
