Check in seconds by entering your **registration number** in our finder.

### Format and fitting of the Varta B19

In terms of format, the Varta B19 measures 207 × 175 × 190 mm (length × width × height) and weighs 11,7 kg. The positive terminal on the right determines which side the cables end up on: it is the detail that causes the most purchasing mistakes, so it is worth checking before ordering. It uses a B13 hold-down and terminal 1, the system that secures it to the vehicle's battery tray. For the replacement to be a direct fit, the space taken by your current battery must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### The Varta B19 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 retains the calcium-silver grid technology that guarantees low self-discharge and reliable cold starting, with no maintenance required.
Designed for the bulk of the car and van fleet, it offers Varta's classic balance between cranking power and durability at a keen 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 substitute when your car does not have Start-Stop and came with a standard battery as original equipment: the same philosophy, without paying over the odds for a chemistry you do not need. *This battery used to belong to Varta's **Black 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 a byword for reliability: original equipment in numerous European vehicles and one of the most proven brands on the market. Replacing your battery with a Varta restores OEM quality — the same performance as the factory-fitted unit — with the manufacturer's backing.
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.
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 B19 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 a terminal or using a trickle charger so it does not discharge below the safe threshold. Checking that the terminals are clean and properly tightened also helps ensure reliable starting.

## Frequently asked questions

### How do I fit the B19 model in my car?

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.

### What is the service life of the B19 model?

Expected lifespan of the Varta B19 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 B19 battery?

Dimensions (length × width × height) are 207×175×190 mm — also written as 207x175x190 mm and correspond to the European L1 case size — 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.

### What barcode does this battery have?

The manufacturer reference (MPN) is B19 and its ETN code is 5454120403122 (short form 545 412 040), the European identifier used in spare-part catalogues. The EAN-13 barcode is 4016987167748. It belongs to the Varta Dynamic SLI range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.

### Will the Varta B19 battery fit my car?

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 B19 fits 175 verified vehicle versions in our database.

### What are the equivalents of the B19 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.
