Varta B33 12V 45Ah 330A is a ready-to-use passenger car battery, sealed and maintenance-free. Delivers the cranking amps the engine needs in cold weather and keeps stable voltage for modern car loads (ECU, sensors, climate control, infotainment).

The Varta B33 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. Measuring 238 × 129 × 227 mm and with the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 45 Ah battery in this format.
According to our database, the Varta B33 is fitted to more than 94 vehicles from brands such as Toyota, Suzuki, Honda, Geely, Maruti and Nissan, among others. For anyone who needs to change the battery in their Toyota or Suzuki, this Varta B33 reproduces the original specifications. It also appears as a replacement in vehicles from LDV, Chery, Mitsubishi, Daihatsu, Mazda, Rover, Subaru and Great Wall, among other manufacturers. Not sure whether it is the one for your car?

In terms of format, the Varta B33 measures 238 × 129 × 227 mm (length × width × height) 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 3, 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 error when replacing a battery.
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 scheme; 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 Europe's conventional petrol and diesel fleet, with ample cranking power and an excellent performance-to-price ratio.
Compared with an EFB or AGM Start-Stop battery, this range puts the emphasis on a keen price and punchy starting in conventional cars. With proper care — avoiding deep discharges and checking the alternator — a battery from this series delivers several years of trouble-free service. 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.
A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has spent decades supplying the assembly lines of the leading car groups. Replacing with Varta means, in practice, giving the vehicle back the battery the manufacturer had in mind.
Varta combines more than a century of experience with Clarios's industrial production: it is the battery many manufacturers choose as standard and one of the most recommended by workshops. Like every lead-acid battery, it is 100% recyclable.
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.
The Varta B33 battery comes with the official manufacturer warranty.
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.

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.
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.
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.
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.
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
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.
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
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.
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.
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.
Expected lifespan of the Varta B33 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.
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.
The manufacturer reference (MPN) is B33 and its ETN code is 5451570333132 (short form 545 157 033), the European identifier used in spare-part catalogues. The EAN-13 barcode is 4016987167540. It belongs to the Varta Dynamic SLI range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.
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 B33 fits 135 verified vehicle versions in our database.
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.
