Varta A5 · Start-Stop battery 12V 95Ah 850A AGM

Varta A5 Dynamic AGM (formerly Silver Dynamic AGM) 95Ah 850A 12V Car Battery

The Varta A5 car battery is the 12 V, 95 Ah model delivering 850 A of cold cranking power (EN), from Varta's Dynamic AGM (formerly Silver Dynamic AGM) range, designed for cars with a Start-Stop system and high electrical demand. It replaces the original battery in cars with the 353 × 175 × 190 mm format without any modifications: the same 95 Ah capacity and the same terminal layout (positive on the right).

• A greater guaranteed number of starts than a conventional battery.
• Reinforced resistance to the partial charges and discharges of daily driving.
• Keeps the vehicle's electronic management correctly calibrated.
• Built for the intensive cycling of the Start-Stop system.

Format and fitting of the Varta A5

The Varta A5 is made in the 353 × 175 × 190 mm format and weighs 26.4 kg. The positive terminal on the right determines which side the cables sit on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. It uses a B13 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must match those three dimensions and the same terminal layout; otherwise you will need adapters or the hold-down will have to change.

The Varta A5 and the Dynamic AGM range

The Dynamic AGM range (gold label) is Varta's top of the range for cars: AGM technology, with the electrolyte absorbed in glass fibre, designed for the most advanced Start-Stop systems and for braking energy recovery.

It withstands thousands of charge and discharge cycles without losing performance and is the only correct choice when the car came with AGM from new. Ideal for vehicles with high electrical consumption and very frequent starts.

In a modern vehicle the battery powers more and more electronics, even with the engine switched off. This series is sized for that draw and for restarting the engine dozens of times a day without losing performance, something a traditional starter battery cannot take. This battery used to belong to Varta's Silver Dynamic AGM range; following the brand's change of commercial naming (2025), it now forms part of the new Dynamic AGM series.

Why choose a Varta battery

When a workshop recommends Varta, it is not down to marketing: it is one of the brands with the lowest return rates in the sector, with application coverage spanning practically the entire European fleet, from the city car to the commercial vehicle.

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.

More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement.

Manufacturer's warranty

The Varta A5 battery comes with the official manufacturer warranty.

Care and maintenance

In a vehicle with Start-Stop the battery works much harder, so make journeys long enough for it to recharge and always replace it with the same type (AGM for AGM, EFB for EFB) so the electronic management is not thrown out of calibration. To get the best from it, avoid very short trips, which prevent it from recharging after each start. Keeping the terminals clean and the battery securely mounted prevents faults caused by vibration in the engine bay.
