Measuring 151 × 99 × 103 mm, it is the direct replacement for power wheelchairs and mobility scooters fitted from the factory with a 15 Ah battery of this format. - No maintenance, no water top-ups. - Approved for air and sea transport (VRLA). - AGM: faster recharging and better cycle resistance than a conventional battery. - Sealed AGM/GEL: safe indoors and in transport. ### Dimensions, polarity and mounting In terms of format, the Long WP15-12SE measures 151 × 99 × 103 mm (length × width × height) and weighs 4.50 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 the Long WP15-12SE is for The Long WP15-12SE is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 4.50 kg. ### The Long WP15-12SE: WP Series range and AGM technology The WP15-12SE is part of the Long **WP 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. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### 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. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Long WP15-12SE 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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. ### Shipping, delivery and returns 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 ### Is the Long WP15-12SE an AGM battery and what are the benefits of AGM? Yes. AGM (Absorbent Glass Mat) technology, 15 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### What are the dimensions of the Long WP15-12SE battery? Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 151×99×103 mm in length × width × height, with the terminals included in the height. ### Long WP15-12SE or Long WP14-12SE: which one to choose? It has the same dimensions, voltage and technology as the WP15-12SE, although it is not a manufacturer-approved equivalent. Compared with the WP15-12SE it has 1 Ah less. It costs €33.60 more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ### Long WP15-12SE or MK Powered ES14-12: which one to choose? It has the same dimensions, voltage and technology as the WP15-12SE, although it is not a manufacturer-approved equivalent. Compared with the WP15-12SE it has 1 Ah less. It costs €76.95 more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ## 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 · 2026-11-11*
