It measures 237 Γ— 127 Γ— 227 mm and the positive terminal on the right, the format sought by anyone replacing a 45 Ah battery in cars. - Reliable cold starts, even after weeks without driving. - Conventional lead-acid: the most proven and economical technology. - Original-equipment build quality without the dealership price. - Direct replacement for the original battery in size and terminals. ### What the Deta DB456 is for The Deta DB456 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 11.40 kg and B00 hold-down. ### Size, terminals and hold-down of the Deta DB456 It has external dimensions of 237 Γ— 127 Γ— 227 mm and weighs 11.40 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 B00 hold-down, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Why choose Deta batteries Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### The Deta DB456: Power range and conventional lead-acid technology Within the Deta catalogue, the **Power** series groups the references designed for this use. The DB456 is the 45 Ah model of that family, with the same performance as its siblings in other sizes. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### How to make it last longer Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. 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. ### Manufacturer's warranty The Deta DB456 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. ### Delivery times 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 is the Deta DB456 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 our blog. 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€” with positive on the right 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 DB456 battery last? Expected lifespan of the Deta DB456 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 dimensions of the Deta DB456 battery? Dimensions (length Γ— width Γ— height) are 237Γ—127Γ—227 mm β€” also written as 237x127x227 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. ### What polarity does the Deta DB456 battery have? Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ### Will the Deta DB456 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 DB456 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Deta DB456? 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 - [VARTA B31](https://baterias.com/gb/battery-varta-b31-12v-45ah-330a) - [TUDOR TB456](https://baterias.com/gb/battery-tudor-tb456-45ah-330a) - [EXIDE EB456](https://baterias.com/gb/battery-exide-eb456-12v-45ah-300a) - [EXIDE EK454](https://baterias.com/gb/battery-exide-ek454-12v-45ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-20*
