Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 23.90 kg. ### The Long LG65-12: LG Series range and GEL technology The LG65-12 is part of the Long **LG 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. A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime. ### Will it fit your current battery tray? It has external dimensions of 350 × 166 × 174 mm and weighs 23.90 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Why choose Long batteries 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. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty. ### How to make it last longer GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. ### Manufacturer's warranty The Long LG65-12 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 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 LG65-12 model a gel battery? Where is it used? Yes, GEL technology (65 Ah): a sealed lead-acid battery whose electrolyte is in gel form. Its maximum charge voltage is lower than an AGM's, so a GEL-specific smart charger is needed. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). ### What are the dimensions of the Long LG65-12 battery? Check the room available in your device, because a single millimetre too much can stop the clamp from closing. Its dimensions are 350×166×174 mm, also written 350x166x174 mm; the height already includes the terminals. ### What polarity does the Long LG65-12 battery have? The LG65-12 has the positive on the right: that is its polarity. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit. ## 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*
