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.
- 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.

How to change the battery
Step-by-step guide to replace your car battery in 15-30 minutes (longer if the battery is under the seat or in the boot) without losing vehicle settings.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery
Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Loosen the bottom hold-down clamp with the same wrench. Lift the battery carefully (it can weigh 15-25 kg). Clean the tray with a brush and baking soda if there is corrosion.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify the engine starts
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
Frequently asked questions
How do I change this battery step by step?
In most cars it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Varta B34 battery last?
Expected lifespan of the Varta B34 is 4 to 6 years in regular car use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Varta B34 battery?
Dimensions (length × width × height) are 238×129×227 mm — also written as 238x129x227 mm — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Under which reference is the Varta B34 listed in catalogues?
The manufacturer reference (MPN) is B34 and its ETN code is 5451580333132 (short form 545 158 033), the European identifier used in spare-part catalogues. The EAN-13 barcode is 4016987167557. It belongs to the Varta Dynamic SLI range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.
Is the B34 valid for my vehicle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The B34 fits 66 verified vehicle versions in our database.
What are the equivalents of the B34 model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop cars. See the "Equivalents" section to view recommended options at the same performance level.
