Varta A16 Dynamic SLI (formerly Black Dynamic) 40Ah 340A 12V Car Battery

The Varta A16 car battery is the 12 V, 40 Ah and 340 A cold cranking (EN) model from Varta's Dynamic SLI (formerly Black Dynamic) range, designed for cars with conventional starting, without a Start-Stop system. Measuring 175 × 175 × 190 mm and with the positive terminal on the right, it is the direct replacement for cars fitted from the factory with a 40 Ah battery in this format.

In short: the Varta A16 (40 Ah, 340 A, 175 × 175 × 190 mm, positive terminal on the right). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Varta B36 and Tudor TB440.

• Direct replacement for the original battery in cars without Start-Stop.
• Reliable cold starting thanks to its high cranking current.
• Long service life with normal use and a charging system in good order.
• Maintenance-free lead-acid technology: no need to top up with water.

Format and fitting of the Varta A16

The Varta A16 is made in the 175 × 175 × 190 mm format and weighs 10,9 kg. The positive terminal on the right determines which side the cables end up on: it is the detail that causes the most purchasing mistakes, so it is worth checking before ordering. It uses a B13 hold-down and terminal 1, the system that secures it to the vehicle's battery tray. For the replacement to be a direct fit, the space taken by your current battery must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

The Varta A16 and the Dynamic SLI range

The Dynamic SLI range is Varta's conventional starting series for cars and vans without a Start-Stop system (identified by the blue label in Varta's new scheme; it replaces the former Blue, Black and Silver Dynamic). It uses lead-calcium technology with PowerFrame grids that reduce self-discharge and extend service life with no maintenance.

It is the balanced option in the catalogue: it covers most of the European fleet of conventional petrol and diesel vehicles, with ample cranking power and an excellent performance-to-price ratio.

Compared with an EFB or AGM Start-Stop battery, this range prioritises a contained cost and punchy starting in conventional cars. With proper care — avoiding deep discharges and checking the alternator — a battery in this series delivers several years of trouble-free service. This battery used to belong to Varta's Black Dynamic, Silver Dynamic or Black Dynamic range; following the brand's commercial renaming (2025), it forms part of the new Dynamic SLI series.

Care and maintenance

To get the most out of it, keep the alternator in good order and avoid leaving lights or accessories on with the engine switched off. Repeated very short journeys are its main enemy: they stop the battery from recharging fully and shorten its life. If the car is going to stand unused for weeks, it is worth disconnecting a terminal or using a trickle charger so it does not discharge below the safe threshold. Checking that the terminals are clean and properly tightened also helps ensure reliable starting.
