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 17.01 kg. ### Will it fit your current battery tray? In terms of format, the Deka 8G22NF measures 228 × 138 × 235 mm (length × width × height) and weighs 17.01 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Deka: the maker behind the 8G22NF 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. ### Technology inside the Deka 8G22NF Within the Deka catalogue, the 8G22NF is the 51 Ah model designed for this application. A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime. ### 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 Deka 8G22NF 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 Orders placed **before 6:00 pm** with the battery in stock ship the same day.

The Deka 8G22NF is GEL: sealed lead-acid in which the electrolyte is a gel. Its maximum charge voltage is lower than an AGM's, so a GEL-specific smart charger is needed. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). ### What are the dimensions of the Deka 8G22NF battery? Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 228x139x235 mm. Height is measured to the top of the terminals. ## 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 · 2026-11-06*
