Varta A12 12V 35Ah 340A 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 A12 car battery is rated at 12 V, 35 Ah and 340 A of cold cranking current (EN), and is designed for passenger cars with conventional starting, without a Start-Stop system. Measuring 196 × 126 × 223 mm, it is the direct replacement for cars fitted from the factory with a 35 Ah battery of this format.
Designed for passenger cars with conventional starting, without a Start-Stop system, the Varta A12 is the direct replacement when your vehicle uses a 35 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 11 kg and 3 terminals.
In terms of format, the Varta A12 measures 196 × 126 × 223 mm (length × width × height) and weighs 11 kg. It uses 3 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
Varta is Europe's leading starter battery manufacturer and original-equipment supplier to most car makers. Every battery is checked on more than a hundred parameters before leaving the plant. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Varta builds the A12 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.
The Varta A12 comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

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 A12; 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)).
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.
The official manufacturer warranty is 2 years and covers manufacturing defects. Coverage includes cell breakdowns, internal short-circuits and abnormal capacity decreases. It does NOT cover misuse (prolonged overcharging, inadequate charger, defective alternator). On confirmed defect after technical inspection, we replace the A12 model at no cost.
In mainland Spain and Portugal it arrives in 24 h if you order before 6:00 pm and the battery is in stock — it leaves the same day and arrives the next business day.

Expected lifespan of the Varta A12 is 4 to 7 years in regular use (depends on technology and climate). 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 196×126×223 mm — also written as 196x126x223 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.
It weighs 11 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).
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 A12 typically fits a wide range of European vehicles thanks to its standard DIN case format.
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.
The product rating, when available, is shown on the product page next to the stars. You can also check our public Trustpilot profile at shop level (4.5/5 from 11,700+ verified reviews). Most-praised points: reliable cold start, lifespan above 5 years and fast delivery; most common complaints mention BMS-equipped cars that need OBD registration after fitting.
