Batería Varta Dynamic AGM A12 35Ah

La Varta Dynamic AGM A12 de 35Ah y 340A es la batería de referencia para vehículos con tecnología Start-Stop y sistemas de frenado regenerativo (KERS). Fabricada con la exclusiva rejilla PowerFrame®, garantiza el máximo rendimiento en las condiciones más exigentes.

  • Recarga hasta 5× más rápida en frenada regenerativa.
  • CCA 340A: Arranque instantáneo en frío extremo.

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.

⏱ 15-30 min🛠 Tools: 10 mm wrench · Protective gloves
  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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 verify this battery is the right one?

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 9:00–18:00 CET).

How do I fit the A12 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 warranty period of this battery?

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.

How long does Varta A12 delivery take?

In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships.

Can I return the Varta A12 battery if it doesn't fit or doesn't work?

Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period.

How much does the Varta A12 battery cost?

The current price at baterias.com is €94.21 (VAT included), updated every 24 hours. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). If you find it cheaper elsewhere (same product and same delivery time), message us on WhatsApp and we will match the price.

Where can I buy the Varta A12 battery?

At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point.

How long does the Varta A12 battery last?

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.

What are the dimensions of the Varta A12 battery?

Dimensions (length × width × height) are 1960×1260×2230 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.

How much does the Varta A12 battery weigh?

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).

Is the A12 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 9:00–18:00 CET). The A12 typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which interchangeable batteries are there for this one?

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.

Which is better: Varta A12 or an alternative from another brand?

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 Stryten Energy) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section.

What real-world experiences are there with this battery?

The product rating, when available, is shown above and in the "Reviews" section. You can also check our public Trustpilot profile at shop level (4.4/5 from 10,267+ 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.
