Varta B18 12V 44Ah 440A is a passenger car battery with factory-guaranteed cranking power and extended service life. OEM quality at white-label prices: calcium-silver grids, low self-discharge and compatible with all modern electrical systems.

The Varta B18 car battery is the 12 V, 44 Ah and 440 A cold cranking (EN) model from Varta's Dynamic SLI (formerly Blue Dynamic) range, designed for cars with conventional starting, without a Start-Stop system. Measuring 207 × 175 × 175 mm and with the positive terminal on the right, it is the direct replacement for cars fitted from the factory with a 44 Ah battery in this format.
This battery is listed as compatible with more than 290 vehicles from manufacturers such as Ford, Renault, Opel, Vauxhall, Nissan and Westfield. If you are looking for a battery for Ford or Renault with these dimensions, the B18 is one of the usual replacement references. Added to that list are models from Volkswagen, Suzuki, Lotus, Rover, Chevrolet, Seat, Fiat and Citroën. It covers 6 original equipment references, one of the widest coverages in its format.

The Varta B18 is made in the 207 × 175 × 175 mm format and weighs 11,5 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. Checking the three dimensions and the terminal positions before buying avoids the most common mistake when replacing a battery.
The Dynamic SLI is Varta's entry range for vehicles with traditional starting (without Start-Stop), bringing what used to be the Blue, Silver and Black Dynamic series together under a single name by technology. Its lead-calcium construction with optimised separators prioritises punchy starting and a long life with no maintenance.
It covers the vast majority of conventional petrol and diesel cars on the European market. It is the sensible choice when you want German manufacturing quality without paying the premium for AGM or EFB technology that the vehicle does not need.
Compared with an EFB or AGM Start-Stop battery, this range prioritises a contained cost and punchy starting in conventional cars. With proper care — avoiding deep discharges and checking the alternator — a battery in 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 automotive groups. Fitting a Varta is, in practice, giving the vehicle back the battery its manufacturer intended.
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.
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.
The Varta B18 battery comes with a 2-year official warranty from the manufacturer.
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.

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.
Three ways: 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 for the B18; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET).
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 B18 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 207×175×175 mm — also written as 207x175x175 mm and correspond to the European LB1 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.
It weighs 10,9 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre).
Nominal capacity 44 Ah[?cca: and [cold-cranking amps 440 A]] at 12 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer.
The manufacturer reference (MPN) is B18 and its ETN code is 5444020443132 (short form 544 402 044), the European identifier used in spare-part catalogues. The EAN-13 barcode is 4016987167519. It belongs to the Varta Dynamic SLI range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.

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.
This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section.
