Its reinforced grid and AGM/GEL separator extend the number of useful cycles well beyond a conventional starter battery. ## Why this deep-cycle battery? - **Daily cycling without wear** handles deep discharges without losing capacity - **Sealed AGM/GEL** no maintenance, no risk of spills - **Thousands of useful cycles** over its full lifetime πŸ”Œ Voltage 12 V ⚑ Capacity 31 Ah C20 πŸ“ Dimensions 195Γ—130Γ—178 mm βš™οΈ Technology GEL 🧭 Polarity Positive on the left ## Description ## Mobility battery Fulbat FPG12-31 31Ah 12V 12*V* Voltage 31*Ah* Capacity Designed for power wheelchairs, mobility scooters and light electric vehicles, the **Fulbat FPG12-31** offers **31 Ah** of deep-cycle capacity with GEL technology. Its 195 Γ— 130 Γ— 178 mm and the positive terminal on the left make it the exact replacement for the 31 Ah battery fitted as standard to many power wheelchairs and mobility scooters. - Approved for air and sea transport (VRLA). - No maintenance, no water top-ups. - Sealed AGM/GEL: safe indoors and in transport. - GEL: excellent resistance to deep discharge and long cycle life. ### What the Fulbat FPG12-31 is for The Fulbat FPG12-31 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 BOLT-M6 terminals. ### Will it fit your current battery tray? In terms of format, the Fulbat FPG12-31 measures 195 Γ— 130 Γ— 178 mm (length Γ— width Γ— height). The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses BOLT-M6 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. ### Fulbat: the maker behind the FPG12-31 Fulbat has manufactured in France since 1978 and specialises in motorcycles and light vehicles. Its catalogue is short and clear, covers almost the whole fleet and works only with sealed, leak-free batteries. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty. ### Technology inside the Fulbat FPG12-31 Within the Fulbat catalogue, the FPG12-31 is the 31 Ah model designed for this application. 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. ### Care and maintenance Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. ### Official warranty The Fulbat FPG12-31 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 [[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 ### How do I fit the FPG12-31 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. ### How long does the Fulbat FPG12-31 battery last? Expected lifespan of the Fulbat FPG12-31 is 4 to 7 years in regular use (depends on technology and climate). 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 are the dimensions of the Fulbat FPG12-31 battery? Dimensions (length Γ— width Γ— height) are 195Γ—130Γ—178 mm β€” also written as 195x130x178 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. ### Which batteries are equivalent to the Fulbat FPG12-31? 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€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-06*
