It measures 120 × 60 × 130 mm, the format sought by anyone replacing a 6 Ah battery in cars. - Reliable cold starts, even after weeks without driving. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Original-equipment build quality without the dealership price. - Direct replacement for the original battery in size and terminals. ### What the Long WP5S-3BP is for Designed for passenger cars with conventional starting, without a Start-Stop system, the Long WP5S-3BP is the direct replacement when your vehicle uses a 6 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.10 kg. ### The Long WP5S-3BP: Starting Series range and AGM technology The WP5S-3BP is part of the Long **Starting Series** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Size, terminals and hold-down of the Long WP5S-3BP The Long WP5S-3BP is made in the 120 × 60 × 130 mm format and weighs 2.10 kg. 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 Long does differently Long (Kung Long Batteries) is one of the world's largest manufacturers of sealed VRLA batteries. Its AGM and GEL series for UPS, mobility, alarms and cycling are found in equipment worldwide as original equipment. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty. ### 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. ### Warranty and coverage The Long WP5S-3BP 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 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 ### Is the Long WP5S-3BP an AGM battery and what are the benefits of AGM? Yes, it is AGM. In an AGM battery such as the WP5S-3BP, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It tolerates heat better and handles more cycles than a conventional battery, which is why it is the required technology with advanced Start-Stop and regenerative braking. ### Is the WP5S-3BP model suitable for Start-Stop cars? Yes, the AGM technology of the WP5S-3BP is built for Start-Stop. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. It works once fitted; on most modern cars, registering it via OBD is advisable so the alternator applies the optimum charging profile. The general recommendation is EFB for basic Start-Stop and AGM where there is regenerative braking (it handles more cycles), unless the car manufacturer says otherwise. ### How do I change this battery step by step? Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way to match the polarity; 6) connect the positive (+) and finally the negative (−). Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. ### How long does the Long WP5S-3BP battery last? There is no exact figure: for a battery such as the Long WP5S-3BP (AGM), a reasonable guide is 5 to 8 years in mild-climate car use with Start-Stop. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop. ### What are the dimensions of the Long WP5S-3BP battery? Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 120x60x130 mm. Height is measured to the top of the terminals. ### Will the Long WP5S-3BP battery fit my car? For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the car handbook disagree, go with what the manufacturer says. ### Which batteries are equivalent to the Long WP5S-3BP? A direct equivalent needs what this WP5S-3BP offers: 120×60×130 mm, the same Ah and CCA and AGM technology. Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop cars. The "Equivalents" section further down lists the recommended alternatives. ### What advantages does the Long WP5S-3BP AGM battery offer over an EFB? Many more charge/discharge cycles than a conventional battery and no leaks: that is what AGM technology brings, with the electrolyte absorbed in glass fibre. Compared with an EFB it resists tilted positions, heavy vibration and extreme temperatures better, and it is the recommended option where there is regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop). ### Is there anything to do after replacing a Start-Stop battery? It is not strictly necessary on most cars, because the alternator detects the change and adapts the charge. The advisable step is to register it via OBD: the charging profile is optimum from the first minute and the battery lasts longer, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). Any garage with an OBD scanner can do it in a few minutes. If you prefer to do it yourself: VCDS / Carista (VAG), Bimmercode (BMW) or iCarsoft. If you do not register the WP5S-3BP, it will keep starting fine while the alternator adjusts the profile over a few days. ## 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 · 2026-11-06*
