- Long service life with normal use and a charging system in good order.
- Maintenance-free lead-acid technology: no need to top up the water.

### Applications of the Varta 066017036 battery

With 66 Ah, the Varta 066017036 is sized for cars with conventional starting, without a Start-Stop system, as a direct replacement for the original battery.

### Format and fitting of the Varta 066017036

The Varta 066017036 is made in the 177 × 175 × 185 mm format. The positive terminal on the right determines which side the cables sit on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. Checking the three dimensions and the terminal positions before buying avoids the most common mistake when replacing a battery.

### The Varta 066017036 and the Classic range

The **Classic** range is Varta's most affordable series, using traditional lead-acid for older vehicles and straightforward applications. It puts reliable starting at the lowest cost first.
It is the basic option when no special performance or cycling resistance is called for: an affordable, direct replacement with Varta's manufacturing backing.
Compared with an EFB or AGM Start-Stop battery, this range prioritises a keen price and punchy starting in conventional cars. With proper care — avoiding deep discharges and keeping an eye on the alternator — a battery in this series gives several years of trouble-free service.

### Why choose a Varta battery

Choosing Varta means going with the reference the car manufacturer itself signed off in the first place. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before it leaves you stranded.
Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year.
Varta is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand labels cannot always promise.

### Manufacturer's warranty

The Varta 066017036 battery comes with **a 2-year official warranty** from the manufacturer.

### Care and maintenance

To get the most out of it, keep the alternator in good condition and avoid leaving lights or accessories switched on with the engine 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 for weeks, it is worth disconnecting the terminal or using a trickle charger so that it does not fall below the safe charge threshold. Making sure the terminals are clean and properly tightened also helps it start reliably.

## Frequently asked questions

### How do I know if the 066017036 model fits my car?

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 066017036; 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 is the Varta 066017036 battery installed in the vehicle?

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. It covers cell failures, internal short-circuits and abnormal capacity drops. Damage from misuse is excluded: prolonged overcharging, unsuitable chargers or a faulty alternator. Once the defect is verified by technical inspection, we replace the 066017036 at no cost.

### When will I receive the 066017036 model?

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.

### Are returns accepted on this battery?

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.

### Where can I buy the Varta 066017036 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 066017036 battery last?

Expected lifespan of the Varta 066017036 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 measurements of the 066017036 model?

Dimensions (length × width × height) are 177×175×185 mm — also written as 177x175x185 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 066017036 battery weigh?

It weighs 9,5 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).

### What is the capacity and CCA of the 066017036 model?

Nominal capacity 66 Ah[?cca: and [cold-cranking amps 360 A]] at 6 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.

### Does this 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 9:00–18:00 CET). The 066017036 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the 066017036 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.

### Which is better: Varta 066017036 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 Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section.
