Description
8G22NF Battery (MK / Deka) – True GEL Deep Cycle 12V (Group 22NF)
The 8G22NF (MK / Deka) is a sealed, maintenance-free true GEL deep-cycle battery built for reliable runtime and repeat cycling. It’s widely specified in mobility equipment and also fits many solar/backup, telecom/communications, and other deep-cycle power needs that require a Group 22NF battery. Deka is same as MK Label made in USA.
Common Applications (Where 8G22NF Is Often Used)
- Mobility scooters
- Power wheelchairs / electric wheelchairs
- Patient lifts & mobility-related equipment (where Group 22NF GEL is specified)
- Solar / PV storage and small backup power systems
- Telecom / communications and standby power
- Marine / RV and other deep-cycle applications (size/spec dependent)
- Dimensions: 8.99″ L x 5.47″ W x 9.24″ H
Why True GEL?
- Spill-proof, sealed VRLA design helps reduce maintenance and mess.
- Deep-cycle design supports repeated cycling vs. typical starting batteries.
- Low self-discharge helps when equipment sits between uses.

Fitment Checklist (Avoid Returns)
- Check your original battery label: confirm it references 8G22NF or Group 22NF.
- Measure the battery compartment: verify length/width/height clearance.
- Confirm terminal type: match your existing terminal style and cable orientation.
- Confirm chemistry & charger: GEL batteries should be charged with a GEL-compatible profile.
Charging Note (Very Important)
GEL batteries require a GEL charging profile. Using the wrong charger setting can reduce battery life. If you’re unsure, send us your charger model and equipment make/model and we’ll help verify compatibility.

FAQ – 8G22NF (MK / Deka) GEL Battery
What is the 8G22NF battery used in?
The 8G22NF is commonly used in mobility scooters and power wheelchairs. It’s also frequently listed for solar/backup, telecom/communications, and other deep-cycle applications where a Group 22NF true GEL battery is specified.
Is 8G22NF a true GEL battery?
Yes—this model is widely published as a true GEL (thixotropic gel electrolyte) VRLA deep-cycle battery.
Do I need a special charger for GEL?
Yes. GEL batteries should be charged using a GEL-compatible profile. If your charger is set for AGM or flooded lead-acid, confirm compatibility before charging.
Why do I see 55Ah, 51Ah, and 58Ah listed?
Battery capacity is published at different discharge rates. Many sources list about 51Ah at the 20-hour rate (C/20) and about 58Ah at the 100-hour rate (C/100).
How do I confirm fitment?
Match the Group 22NF size, confirm the dimensions/clearance, and verify your terminal type and cable orientation against the original battery.
