Its 260 Γ— 181 Γ— 276 mm make it the exact replacement for the 235 Ah battery fitted as standard to many power wheelchairs and mobility scooters. - Sealed AGM/GEL: safe indoors and in transport. - Good balance of capacity, cranking power and price. - Approved for air and sea transport (VRLA). - No maintenance, no water top-ups. ### What the Deka GC25 is for With 235 Ah, the Deka GC25 offers the daily range that power wheelchairs, mobility scooters and light electric vehicles need, with a sealed construction that is safe indoors. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 30.84 kg. ### Dimensions, polarity and mounting In terms of format, the Deka GC25 measures 260 Γ— 181 Γ— 276 mm (length Γ— width Γ— height) and weighs 30.84 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. ### Technology inside the Deka GC25 Within the Deka catalogue, the GC25 is the 235 Ah model designed for this application. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Why choose Deka batteries Deka (East Penn Manufacturing) is the largest single-site lead battery manufacturer in the United States, with full control of the process from lead recycling to the finished battery. We guarantee that every Deka arrives new, charged and with the manufacturer's full warranty. ### Warranty and coverage The Deka GC25 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. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Delivery times and returns Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### How is the Deka GC25 battery installed in the vehicle? 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 Deka GC25 battery last? Expected lifespan of the Deka GC25 is 4 to 6 years in regular device use without 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 are the dimensions of the Deka GC25 battery? Dimensions (length Γ— width Γ— height) are 260Γ—181Γ—276 mm β€” also written as 260x181x276 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 interchangeable batteries are there for this one? 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. ## Reviews - **Average rating**: 4.75 / 5 (51 reviews) ## 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· 2026-10-04*
