From 33 to 220 Ah, sealed and deep cycle. Gel withstands deep discharges every single day, making it the recommended **GEL mobility battery** for intensive users covering long distances: maximum cycle life, maintenance-free and spill-proof. ## MK GEL: maximum service life for the daily-use wheelchair The **MK GEL** range is MK Battery's premium mobility option (East Penn group): gelified electrolyte, sealed-for-life battery and better deep cycling endurance than an equivalent AGM. It is the recommended technology when a power wheelchair or mobility scooter is used every day and discharged deeply. ### MK GEL models and applications - **MK 8GU1** (33 Ah): small mobility scooter. - **MK 8G24** (73.6 Ah): standard power wheelchair. - **MK 8G27** (89 Ah): mid-size chair or scooter. - **MK 8G31** (97.6 Ah): bariatric chair. - **MK 8G8DLTP** (220 Ah): long-range bariatric chair. ### How to choose your GEL mobility battery Pick the reference with the same capacity (Ah) and dimensions as the original battery; on 24 V equipment, renew both 12 V batteries at the same time. Always charge with a GEL-profile charger — such as the 24 V MK chargers — and compare models and prices in our [battery comparator](/gb/comparator). ## Frequently asked questions about MK GEL batteries ### **Is GEL worth it over AGM in a wheelchair?** Yes when use is daily and intensive: gel withstands more deep discharge cycles. For occasional or seasonal use, an MK AGM offers a better price. ### **How long does an MK GEL battery last?** It depends on discharge depth and charging: fully recharged after each use with a GEL profile, it outlasts an equivalent AGM in daily use. ### **Is it compatible with Permobil, Invacare or Sunrise Medical?** Yes. MK Battery is approved by the leading wheelchair manufacturers; choose the reference with the same capacity and dimensions as the battery your equipment came with. ### **Which model should I choose for more range?** For the same available space, the highest-capacity reference: for example, the 220 Ah MK 8G8DLTP is designed for long-range bariatric chairs.
