Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31.07 kg and B (T876) terminals. ### Dimensions, polarity and mounting The MK Powered E31 SLD G is made in the 328 × 171 × 247 mm format and weighs 31.07 kg. It uses B (T876) terminals, the system that anchors and connects it in the vehicle. 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. ### The MK Powered E31 SLD G: Mk GEL range and GEL technology The **Mk GEL** is the MK Powered range the E31 SLD G 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. ### Why choose MK Powered batteries MK batteries are the standard in the electric mobility sector: sealed, approved for air transport and with the consistency that wheelchair manufacturers demand as original equipment. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Official warranty The MK Powered E31 SLD G 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. ### Care and maintenance 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. ### 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 MK Powered E31 SLD G a GEL battery? What is GEL used for? Yes, GEL technology (97.6 Ah): a sealed lead-acid battery whose electrolyte is 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. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). ### What are the measurements of the E31 SLD G model? The MK Powered E31 SLD G takes up 328×171×248 mm (length, width and height, terminals included). Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing. ## 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 · 2026-11-12*
