The Varta A16 in practice
When not to choose it
It is a conventional battery: not for Start-Stop cars, which need EFB or AGM depending on what they left the factory with. Never go below the original capacity and cranking either.

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.
Vehicles compatible with the Varta A16 battery
The Varta A16 is compatible with more than 28 vehicles: it is fitted as standard or as a replacement by brands such as Fiat, Lancia, Citroën, Seat, Autobianchi and Peugeot. If you are looking for a battery for Fiat or Lancia with these dimensions, the A16 is one of the usual replacement references. The compatibility list also includes models from Zastava, Aixam and Innocenti. Not sure whether it is the right one for your car? Check in seconds by entering your registration number in our finder.
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 Dynamic SLI). 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 Dynamic SLI, Dynamic SLI or Dynamic SLI range; following the brand's commercial renaming (2025), it forms part of the new Dynamic SLI series.
Why choose a Varta battery
Manufactured by Clarios to German standards, Varta is one of the world's benchmark brands in starter batteries and an OEM supplier to the leading car makers. Choosing it as a replacement guarantees specifications equal to or better than the originals.
Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year.
Varta is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand labels cannot always assure.
Manufacturer's warranty
The Varta A16 battery comes with the official manufacturer warranty.
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.

It is the AGM of the same case: more cold cranking, faster charging and far more resistance to cycling and heat than the A16. Compared with the A16 it has 80 A of cold cranking more. It costs 40,30 € more. Mandatory if the original was AGM; in a car without Start-Stop the A16 does the job and AGM is a bonus in cranking and durability, not a necessity.

Frequently asked questions
How is the Varta A16 battery installed in the vehicle?
Tool: a 10 mm spanner. Time: 15-30 minutes on almost every car, and up to double if the battery is not under the bonnet but in the boot or under a seat. If the car manufacturer lists any extra step in the handbook, follow it. More detail in how to replace the car battery. The right order: engine off and key out; disconnect the negative (−) first, then the positive (+); release the hold-down clamp, lift out the old battery and seat the new one in the same position (positive on the right), keeping the polarity; reconnect the positive (+) first and the negative (−) last.
What is the service life of the A16 model?
As a rough estimate, the Varta A16 typically lasts 4 to 6 years in regular car use without Start-Stop; it is a guide figure, not a guaranteed period. What weighs most: temperature (cold makes starts harder and intense heat evaporates the electrolyte), frequent short trips, the condition of the alternator and charging system, power draw while parked and maintenance, not forgetting the type of car and Start-Stop.
What are the measurements of the A16 model?
Check the room available in your car, because a single millimetre too much can stop the clamp from closing. Its dimensions are 175×175×190 mm, also written 175x175x190 mm; the height already includes the terminals.
What polarity does the Varta A16 battery have?
Polarity of the Varta A16: positive on the right. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Seen from the front, terminals towards you, the positive (+) is the post with the red ring.
Under which reference is the Varta A16 listed in catalogues?
Parts catalogues list it under ETN 540 406 034 (in full, 5404060343122); the manufacturer's reference is A16 and its EAN-13 is 4016987143599. It belongs to the Varta Dynamic SLI range. Any of the three works for getting a quote or comparing prices without mix-ups.
Is the A16 valid for my vehicle?
Three routes: the "Compatible vehicles" tab on this page, with the vehicles verified by our technical team; your number plate in the finder, from which DGT/DVLA/KBA detect model and engine; and WhatsApp, with make, model, engine and year, during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). According to our data, 28 verified vehicle versions are compatible with the A16. Always cross-check with what the car manufacturer states in the owner's handbook.
Which interchangeable batteries are there for this one?
Technology matters too: in Start-Stop cars, an EFB cannot be replaced with a conventional battery. The options at the same level are in the "Equivalents" section of this page. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the A16, 40 Ah (340 A cranking).
Varta A16 or Varta B36: which one to choose?
It is the bigger sister of the A16 in the same Varta range. Compared with the A16 it has 4 Ah more and 80 A of cold cranking more. It costs 20,50 € less. If the tray takes the size, extra reserve never hurts; for a daily-driven petrol car the extra is not needed.
Varta A16 or Varta A10: which one to choose?
It is the AGM of the same case: more cold cranking, faster charging and far more resistance to cycling and heat than the A16. Compared with the A16 it has 80 A of cold cranking more. It costs 40,30 € more. Mandatory if the original was AGM; in a car without Start-Stop the A16 does the job and AGM is a bonus in cranking and durability, not a necessity.
