Varta H3 Dynamic SLI (formerly Silver Dynamic) 100Ah 830A 12V Car Battery

The Varta H3 car battery is the 12 V, 100 Ah model delivering 830 A of cold cranking power (EN), from Varta's Dynamic SLI (formerly Silver Dynamic) range, designed for cars with conventional starting, without a Start-Stop system. It replaces the original battery in cars with the 353 × 175 × 190 mm format without any modifications: the same 100 Ah capacity and the same terminal layout (positive on the right).

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

Format and fitting of the Varta H3

In format, the Varta H3 measures 353 × 175 × 190 mm (length × width × height) and weighs 22.6 kg. The positive terminal on the right determines which side the cables end up on: this is the detail behind more wrong purchases than any other, so it is worth checking before you order. It takes a B13 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Varta H3 and the Dynamic SLI range

The Dynamic SLI range is Varta's conventional starter series for cars and vans without a Start-Stop system (identified by the blue label in Varta's new system; 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 starting power and excellent value for money.

This series uses lead-acid technology with plates optimised for a good balance between starting power and service life. It is the natural replacement when your car has no Start-Stop and came with a standard battery from the factory: the same thinking, without paying over the odds for a chemistry you do not need. This battery used to belong to Varta's Silver Dynamic, Silver Dynamic or Black Dynamic range; following the brand's commercial renaming (2025), it now forms part of the new Dynamic SLI series.

Why choose a Varta battery

When a workshop recommends Varta it is not doing so out of marketing: it is one of the brands with the lowest return rates in the sector, and its application coverage takes in practically the whole European fleet, from the small hatchback 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.

Varta's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life.

Manufacturer's warranty

The Varta H3 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 worst enemy: they stop the battery from recharging fully and shorten its life. If the car is going to stand for weeks, it is worth disconnecting a terminal or fitting a trickle charger so that it does not discharge below the safe threshold. Checking that the terminals are clean and properly tightened also helps it start first time.
