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 45 Ah C20 πŸ“ Dimensions 236Γ—127Γ—224 mm βš–οΈ Weight 8,98 kg 🏷️ Model Starting Series ## Description ## Car battery Long 46B24R Starting Series 45Ah 12V 12*V* Voltage 45*Ah* Capacity 8.98*kg* Weight The **Long 46B24R car battery** is rated at **12 V**, **45 Ah** from the **Starting Series** range, and is designed for passenger cars with conventional starting, without a Start-Stop system. It replaces the original battery without adaptation in cars with a 236 Γ— 127 Γ— 224 mm format: same 45 Ah capacity. - Original-equipment build quality without the dealership price. - Reliable cold starts, even after weeks without driving. - Designed to last several years under normal daily use. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). ### What the Long 46B24R is for The Long 46B24R 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 8.98 kg. ### The Long 46B24R within the Starting Series range The **Starting Series** is the Long range the 46B24R belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. ### Dimensions, polarity and mounting The Long 46B24R is made in the 236 Γ— 127 Γ— 224 mm format and weighs 8.98 kg. 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 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. ### How to make it last longer 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. ### Warranty and coverage The Long 46B24R 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 Order **before 6:00 pm** 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 **14 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? For the detail, read our guide to replacing the car battery and, if in doubt, the owner's handbook or a main dealer. 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 (βˆ’) before positive (+); refitting, positive (+) before negative (βˆ’). 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 (polarity). ### How many years does this battery last? As a rough estimate, the Long 46B24R typically lasts 4 to 7 years in regular use (depends on technology and climate); it is a guide figure, not a guaranteed period. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance, plus the car itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte. ### What are the dimensions of the Long 46B24R battery? The Long 46B24R takes up 236Γ—127Γ—224 mm (length, width and height, terminals included). Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. ### Will the Long 46B24R battery fit my car? Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your car is not there, send us make, model, engine and year on WhatsApp and we will reply 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. ### What are the equivalents of the 46B24R model? A direct equivalent needs what this 46B24R offers: 236Γ—127Γ—224 mm, the same Ah and CCA. 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. ## 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· 2026-11-06*
