It replaces the original battery without adaptation in cars with a 187 × 127 × 220 mm format: same 35 Ah capacity and the positive terminal on the right. - Conventional lead-acid: the most proven and economical technology. - Reliable cold starts, even after weeks without driving. - Direct replacement for the original battery in size and terminals. - Original-equipment build quality without the dealership price. ### What the Deta DB356A is for The Deta DB356A covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 8.90 kg and Korean B1 Long hold-down. ### Dimensions, polarity and mounting The Deta DB356A is made in the 187 × 127 × 220 mm format and weighs 8.90 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a Korean B1 Long hold-down, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### The Deta DB356A: Power range and conventional lead-acid technology Within the Deta catalogue, the **Power** series groups the references designed for this use. The DB356A is the 35 Ah model of that family, with the same performance as its siblings in other sizes. The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop. ### Deta: the maker behind the DB356A Deta is the German brand of the Exide group: batteries built with original-equipment technology and a very complete range for cars, Start-Stop, trucks, motorcycles and leisure. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Warranty and coverage The Deta DB356A 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. ### Care and maintenance On batteries with filler caps, check the electrolyte level and top up only with distilled water. Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge. ### Shipping, delivery and returns 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. ## Frequently asked questions ### How do I fit the DB356A model in my car? Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the right) to match the polarity; 6) connect the positive (+) and finally the negative (−). Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. If the car manufacturer lists any extra step in the handbook, follow it. More detail in how to replace the car battery. ### How long does the Deta DB356A battery last? As a rough estimate, the Deta DB356A typically lasts 4 to 6 years in regular car use without Start-Stop; it is a guide figure, not a guaranteed period. What weighs most: temperature (cold makes starts harder and intense heat evaporates the electrolyte), frequent short trips, the condition of the alternator and charging system, power draw while parked and maintenance, not forgetting the type of car and Start-Stop. ### What are the measurements of the DB356A model? Length × width × height: 187x127x220 mm. Height is measured to the top of the terminals. Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. ### What polarity does the Deta DB356A battery have? Polarity of the Deta DB356A: positive on the right. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. ### Does this battery fit my car? The DB356A typically fits a wide range of European vehicles thanks to its standard DIN case format. Three routes: the "Compatible vehicles" tab on this page, with the vehicles verified by our technical team; your number plate in the finder, from which DGT/DVLA/KBA detect model and engine; and WhatsApp, with make, model, engine and year, during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the car handbook disagree, go with what the manufacturer says. ### Which interchangeable batteries are there for this one? Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop cars. The "Equivalents" section further down lists the recommended alternatives. A battery interchangeable with the Deta DB356A must match it on dimensions (187×127×220 mm), polarity (positive on the right), capacity (35 Ah) and cranking current (240 A). ### Deta DB356A or Tudor TB356A: which one to choose? The Tudor alternative that fits where the DB356A goes, with the same polarity. Compared with the DB356A it has the same Ah and cranking power. It costs €45.50 more. A straight swap with nothing to adapt; the difference is the price and the brand you prefer. ### Deta DB356A or Tudor TA386: which one to choose? Same case and same fitting as the DB356A, from Tudor. Compared with the DB356A it has 3 Ah more and 60 A of cold cranking more. It costs €64.80 more. If you want to save or the DB356A is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty. ## Equivalent batteries - [TUDOR TB356A](https://baterias.com/gb/battery-tudor-tb356a-35ah-240a) - [TUDOR TA386](https://baterias.com/gb/battery-tudor-ta386-12v-38ah-300a) - [EXIDE EB356A](https://baterias.com/gb/battery-exide-eb356a-12v-35ah-240a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-13*
