Who we are: baterias.com, Kronotech Solutions S.L. and the Kronobat brand

At baterias.com we are official Varta wholesale distributors - the world's best-selling battery brand - and exclusive specialists in batteries for cars, motorcycles, trucks and mobility vehicles. We don't sell spare parts in general: only batteries, and that specialisation makes us the benchmark in the sector across Spain, Portugal and Europe.

With over 200,000 satisfied customers and more than 12,100 verified reviews on Trustpilot (4.5/5 rating) - audited by the independent company Trustpilot, unfiltered and unedited - we are the highest-rated battery shop in Spain. Unlike other stores that manage their own reviews, at baterias.com we invite every single customer without exception to share their experience, whether positive or not. That radical transparency is what has allowed us to build the largest and most loyal customer community in the sector.

Official Varta wholesale distributors: the guarantee of buying at the source

Being an official Varta wholesale distributor is not a commercial title: it is a distinction that Varta grants only to companies that meet its highest standards of quality, logistical capacity and technical product knowledge. Varta is the reference battery manufacturer for the world's leading car manufacturers - including Volkswagen, BMW, Mercedes-Benz and Audi - and its network of official distributors in Spain is very small.

When you buy a Varta battery at baterias.com, you are buying directly at the origin of the supply chain. No middlemen, no regional distributors, no stock that has been sitting in a third-party warehouse for months. The battery goes from Varta to our logistics centres and from there directly to your door - with its full service life intact and with the official manufacturer's warranty.

Exclusive battery specialists - not general spare parts dealers

Most online stores that sell batteries are actually automotive spare parts stores that include batteries in their catalogue as just another product, alongside filters, wipers, oils and brake pads. At baterias.com we do exactly the opposite: we focus exclusively on batteries.

Our team has an in-depth knowledge of every technology - lead-acid, AGM, EFB, GEL, Lithium - and every application - starting, deep cycle, traction, stationary, solar energy, electric mobility. We know which battery each vehicle needs, why, and what the difference is between choosing well or badly. That specialist knowledge is what we make available to you for free with every enquiry.

100% original batteries from the sector's leading brands

We work directly with the world's most recognised battery manufacturers: Varta, Exide, Tudor, Optima, Odyssey, MK and Genesis, among others. Every battery we sell is 100% original, sourced directly from the factory and backed by the official manufacturer's warranty. We do not sell imitation products, reconditioned batteries or second-hand stock.

For those looking for the best value for money without sacrificing guarantees, we also offer Kronobat, our exclusive brand manufactured to the same production standards as premium brands. Kronobat is designed to be compatible with the main vehicle models on the market and represents a highly reliable alternative at a significantly lower price.

All our batteries comply with current European regulations and are approved for use in vehicles of all makes and models. Whether your vehicle requires an AGM battery for a Start-Stop system, an EFB for mild hybrids or a high-discharge battery for solar energy installations, we have the right technical solution.

Best price guaranteed: low-cost structure with no middlemen

No physical stores. No large commercial structures. No purchases through wholesalers or intermediate distributors. We buy directly from manufacturers, in large volumes, and pass those savings on entirely to the final price. The result is clear: our batteries are up to 40% cheaper than in a physical store and between 10% and 20% more affordable than most competitor websites.

Our high sales volume also gives us a privileged negotiating position with manufacturers, allowing us to access pricing conditions that no small or medium-sized store can match. That advantage goes directly to the customer - not to our margin.

Freshly manufactured batteries: the manufacturing date matters more than you think

A car battery starts losing capacity from the moment it leaves the factory, even if it has never been used. A battery stored for 6, 9 or 12 months in a wholesaler's warehouse arrives at your vehicle with a significant portion of its useful life already consumed - even if it is brand new.

At baterias.com this does not happen. Our extremely high sales turnover guarantees that no battery remains in our logistics centres for more than one week. The battery you buy today left the factory very recently, is in optimal condition and has its full useful life ahead of it.

Urgent 24-hour delivery on the Peninsula - we monitor every order

We understand that when a battery fails, time matters. 90% of our orders are delivered within 24 hours on the Peninsula via our contracted express courier service. If you place your order before 6:00 pm, your battery ships the same day.

Shipments to mainland Spain and Portugal include free returns. If for any reason the battery is not right for your vehicle, we arrange the collection at no additional cost to you.

Home battery installation: the most convenient change you will ever make

In modern vehicles - especially those with Start-Stop systems, energy management or battery coding - an incorrect installation can cause electronic errors or void the warranty. At baterias.com we have solved this problem at its root with our home installation service.

Our specialist technicians travel to wherever you are and carry out the battery replacement on the spot. The service is currently available in Madrid, Barcelona, Malaga, Seville, Valencia and Zaragoza, with minimal response times.

Free technical advice from battery specialists

At baterias.com we have a team of battery technical specialists available to advise you with no obligation. These are not call centre agents with a script: they are professionals with in-depth knowledge of every technology and every application. Call us on 951 870 157 or message us on WhatsApp and we will get back to you within minutes.

Our goal is not to sell you a battery. Our goal is for you to make the best possible decision - and for everything to work exactly as it should when the battery arrives at your door.
