A VARTA 12V 70Ah battery marked TERS (or Reverse/L+) indicates a model with reverse polarity (the positive terminal is on the right when looking at the battery from the terminal side). This is the most popular standard for European cars.

Key Benefits and Technologies
For Start-Stop systems: Ideal for continuous stop-start operation. Provides power for the air conditioning, music system, and navigation system when the engine is turned off at traffic lights.

Energy Regeneration: Efficiently recharges the battery from the braking system, which is impossible with conventional batteries.

Maximum safety: The electrolyte is absorbed into fiberglass mats. The battery is completely sealed, allowing it to be transported in any position, and is resistant to vibration and tilt.

Powerful starting (760A): Guarantees instant starting of even heavy diesel engines in extreme cold (down to -35°C).

Deep discharge protection: Unlike conventional batteries, AGM batteries recover much faster after short trips and do not lose capacity if the car has been parked for a long time.
