Delivers the cranking amps the engine needs in cold weather and keeps stable voltage for modern car loads (ECU, sensors, 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 85 Ah C20 πŸ”‹ Cold cranking 800 A EN-1 πŸ“ Dimensions 306Γ—192Γ—192 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 19,5 kg 🏷️ Model EXIDE Excell ## Description ## Car battery Exide EB858 Excell 85Ah 800A 12V 12*V* Voltage 85*Ah* Capacity 800*A* Cold cranking 19.50*kg* Weight The **Exide EB858 car battery** is rated at **12 V**, **85 Ah** and **800 A** of cold cranking current (EN) from the **Excell** range, and is designed for passenger cars with conventional starting, without a Start-Stop system. Measuring 306 Γ— 192 Γ— 192 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 85 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. ### What the Exide EB858 is for With 85 Ah, the Exide EB858 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 19.50 kg, EN taper post terminals and B1 hold-down. ### Will it fit your current battery tray? It has external dimensions of 306 Γ— 192 Γ— 192 mm and weighs 19.50 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 B1 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### What Exide does differently Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### The Exide EB858: Excell range and conventional lead-acid technology Within the Exide catalogue, the **Excell** series groups the references designed for this use. The EB858 is the 85 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. ### Usage and maintenance tips 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. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. ### Manufacturer's warranty The Exide EB858 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. ### When you get it and how to return it 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 EB858 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 many years does this battery last? Expected lifespan of the Exide EB858 is 4 to 7 years in regular use (depends on technology and climate). 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 Exide EB858 battery? Dimensions (length Γ— width Γ— height) are 306Γ—192Γ—192 mm β€” also written as 306x192x192 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 Exide EB858 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 EB858 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. ## 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· 2026-09-29*
