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 WP15-12NSE: WP Series range and AGM technology Within the Long catalogue, the **WP Series** series groups the references designed for this use. The WP15-12NSE is the 15 Ah model of that family, with the same performance as its siblings in other sizes. AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### Size, terminals and hold-down of the Long WP15-12NSE It has external dimensions of 151 Γ— 99 Γ— 98 mm and weighs 4.50 kg. 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. ### Why choose Long batteries 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. 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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. 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 WP15-12NSE 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. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] 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 Long WP15-12NSE an AGM battery and what are the benefits of AGM? Yes. The WP15-12NSE from Long uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How do I fit the WP15-12NSE model in my device? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (βˆ’) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the service life of the WP15-12NSE model? Expected lifespan of the Long WP15-12NSE is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What size is this battery? Dimensions (length Γ— width Γ— height) are 151Γ—99Γ—98 mm β€” also written as 151x99x98 mm β€” following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### What are the equivalents of the WP15-12NSE model? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology β€” an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ## 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 2015. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-14*
