About MK Sealed AGM batteries:

• Absorbed Glass Mat (AGM) construction — electrolyte held in fiberglass mats
• Sealed valve-regulated lead acid (VRLA) — maintenance-free, non-spillable
• Best suited for lighter-duty mobility applications
• F.A.A., IATA, and UPS approved for shipping

Note from MK Battery: "MK Battery considers AGM batteries to be suitable for lighter duty mobility equipment only. AGM batteries used in more robust applications such as complex rehab mobility devices, where daily deep discharges are the norm, may void the warranty." For heavy-duty applications, consider the equivalent Gel battery instead.
