It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 199 × 166 × 171 mm format: same 45 Ah capacity and the positive terminal on the right. - Thousands of useful cycles over its lifetime. - Standard replacement format for wheelchairs and scooters. - GEL technology: gelled electrolyte, fully sealed and maintenance-free. - Designed to be discharged and recharged daily without losing capacity. ### What the Long LG45-12N is for With 45 Ah, the Long LG45-12N offers the daily range that power wheelchairs, mobility scooters and light electric vehicles need, with a sealed construction that is safe indoors. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 15 kg. ### The Long LG45-12N: LG Series range and GEL technology The **LG Series** is the Long range the LG45-12N 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. GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM. ### Size, terminals and hold-down of the Long LG45-12N In terms of format, the Long LG45-12N measures 199 × 166 × 171 mm (length × width × height) and weighs 15 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. 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 batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### How to make it last longer Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. ### Official warranty The Long LG45-12N comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### Shipping, delivery and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the Long LG45-12N a GEL battery? What is GEL used for? Yes, this model is a GEL battery: sealed lead-acid with the electrolyte in gel form. Take care when charging: it requires a smart charger with a GEL mode, because it accepts a lower charge voltage than an AGM. Deep discharges are its strong point, so it suits cyclic use: solar, motorhomes, electric wheelchairs or motorcycles. ### What are the measurements of the LG45-12N model? It measures 199×166×171 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### What polarity does the Long LG45-12N battery have? It has the positive on the right (polarity). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering. ### Long LG45-12N or Long LG50-12N: which one to choose? Same family as the LG45-12N, one step up in performance. Compared with the LG45-12N it has 5 Ah more. It costs €112.80 more. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the LG45-12N does the job. ### Long LG45-12N or Long LG50-12: which one to choose? It is the bigger sister of the LG45-12N in the same Long range. Compared with the LG45-12N it has 5 Ah more. It costs €196.70 more. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the LG45-12N does the job. ## Equivalent batteries - [LONG LG50-12](https://baterias.com/gb/battery-long-lg50-12-12v-50ah) - [LONG LG50-12N](https://baterias.com/gb/battery-long-lg50-12n-12v-50ah) ## 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 · 2026-11-07*
