It replaces the original battery without adaptation in cars with a 187 Γ— 127 Γ— 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 Γ— 127 Γ— 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 [[ks:cutoff]]**: 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 **[[ks:return_days]] 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? 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 (βˆ’) 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 β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Deta DB356A battery last? Expected lifespan of the Deta DB356A 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 DB356A model? Dimensions (length Γ— width Γ— height) are 187Γ—127Γ—220 mm β€” also written as 187x127x220 mm β€” 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. ### 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DB356A 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 β€” 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. ## 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 β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-09-28*
