Varta B34 · Car battery 12V 45Ah 330A

Varta B34 Dynamic SLI (formerly Blue Dynamic) 45Ah 330A 12V Car Battery

The Varta B34 car battery is the 12 V, 45 Ah model with 330 A of cold cranking power (EN) from Varta's Dynamic SLI (formerly Blue Dynamic) range, intended for cars with conventional starting, without a Start-Stop system. Its 238 × 129 × 227 mm dimensions and positive terminal on the left make it the exact replacement for the 45 Ah battery fitted as standard in many cars.

In short: the Varta B34 (45 Ah, 330 A, 238 × 129 × 227 mm, positive terminal on the left). 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: Tudor TB455 and Exide EB455.

• 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 B34

The Varta B34 is made in the 238 × 129 × 227 mm format and weighs 11,7 kg. The positive terminal on the left determines which side the cables end up on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. It uses a B00 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. Before replacing it, measure the space your current battery occupies: if it matches on all three dimensions and on terminal position, the swap is direct and needs no adapters.

The Varta B34 and the Dynamic SLI range

The Dynamic SLI series (blue label) is Varta's lead-acid line for cars with conventional starting, without Start-Stop. It succeeds the Blue, Silver and Black Dynamic ranges and keeps the calcium-silver grid technology that guarantees low self-discharge and reliable cold starting, with no maintenance required.

Aimed at the bulk of the car and van fleet, it offers Varta's classic balance between cranking power and durability at a moderate price: the logical replacement for the original battery in a car without Start-Stop.

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

Why choose a Varta battery

Varta is an original equipment (OEM) supplier to a good share of Europe's car manufacturers: many cars leave the factory with a Varta fitted. Buying a replacement means, in most cases, refitting the original battery with the same quality and the brand's official warranty.

Varta batteries are made under the Clarios group with German technology and quality controls that make them one of the best-selling choices in Europe. As a lead battery, it is 100% recyclable through any collection point.

Varta is Europe's leading maker of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makes cannot always promise.

Manufacturer's warranty

The Varta B34 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 the terminal or using a trickle charger so it does not drop below the safe threshold. Making sure the terminals are clean and properly tightened also helps towards reliable starting.
