Delivers reliable cold-cranks even after weeks of inactivity and supports stable auxiliary loads (lights, climate control, infotainment). ## Why this car battery? - **Original-equipment quality** without dealership prices - **Lasts 4 to 6 years** buy once instead of twice - **Real human tech support** if you have any doubts before buying πŸ”Œ Voltage 12 V ⚑ Capacity 35 Ah C20 πŸ”‹ Cold cranking 240 A EN-1 πŸ“ Dimensions 187Γ—127Γ—220 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 8,9 kg 🏷️ Model DETA Power ## Description ## Car battery Deta DB357 Power 35Ah 240A 12V 12*V* Voltage 35*Ah* Capacity 240*A* Cold cranking 8.90*kg* Weight The **Deta DB357 car battery** is rated at **12 V**, **35 Ah** and **240 A** of cold cranking current (EN) from the **Power** range, and is designed for passenger cars with conventional starting, without a Start-Stop system. Measuring 187 Γ— 127 Γ— 220 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 35 Ah battery of this format. - Good balance of capacity, cranking power and price. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). - Low self-discharge: copes with long stops without losing charge. - Designed to last several years under normal daily use. ### Dimensions, polarity and mounting In terms of format, the Deta DB357 measures 187 Γ— 127 Γ— 220 mm (length Γ— width Γ— height) and weighs 8.90 kg. The positive terminal on the left 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 B00 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. ### What the Deta DB357 is for The Deta DB357 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 B00 hold-down. ### The Deta DB357: Power range and conventional lead-acid technology Within the Deta catalogue, the **Power** series groups the references designed for this use. The DB357 is the 35 Ah model of that family, with the same performance as its siblings in other sizes. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### What Deta does differently Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. All the Deta batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Deta DB357 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 In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. ### Delivery times and returns Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### How do I change this battery step by step? 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. ### What is the service life of the DB357 model? Expected lifespan of the Deta DB357 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 size is this battery? 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. ### Will the Deta DB357 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 DB357 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the DB357 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 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 TB357](https://baterias.com/gb/battery-tudor-tb357-35ah-240a) - [EXIDE EB357](https://baterias.com/gb/battery-exide-eb357-12v-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· 2026-10-08*
