Measuring 306 × 192 × 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 × 192 × 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 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 EB858 model in my car? Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog. On most cars it is a 15-30 minute job needing only a 10 mm spanner (up to twice as long when the battery is under a seat or in the boot). What matters most is the terminal order: removing, negative (−) before positive (+); refitting, positive (+) before negative (−). In between, with the engine off and the key out, release the clamp and fit the new battery the same way round as the original, positive on the left (polarity). ### How many years does this battery last? As a rough estimate, the Exide EB858 typically lasts 4 to 7 years in regular use (depends on technology and climate); it is a guide figure, not a guaranteed period. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of car and Start-Stop also count. ### What are the dimensions of the Exide EB858 battery? Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. The Exide EB858 takes up 306×192×192 mm (length, width and height, terminals included), with a B1 hold-down. ### What polarity does the Exide EB858 battery have? Polarity of the Exide EB858: positive on the left. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Seen from the front, terminals towards you, the positive (+) is the post with the red ring. ### Will the Exide EB858 battery fit my car? The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The car manufacturer's specifications always take priority over our tables. ### Which interchangeable batteries are there for this one? See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop cars an EFB is not swapped for a conventional battery. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the EB858, 85 Ah (800 A cranking). ## 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*
