Your Pride Jazzy EVO 614HD carries 450 pounds while still turning inside 22 inches, which is a combination very few heavy duty power chairs manage. Mid-Wheel 6 technology puts the drive wheels under the seat, full independent front and rear Active-Trac ATX suspension smooths out thresholds and uneven ground, and 13.75 inch perforated drive wheels with 3 inches of clearance handle far more than smooth floors. A 60 amp Dynamic LiNX controller ties it together, and two Group 22NF batteries supply the energy as a 24 volt pair.
Before you order, confirm which EVO 614 you have, because the two models take different batteries. The 614HD is the 450 pound capacity version and runs Group 22NF batteries, which is what this pair is built for. The standard EVO 614 carries 300 pounds and runs smaller U1 batteries instead. Both chairs have two batteries, so counting them will not tell you which you own. Check the label on your current batteries: NF-22 or 22NF means you are in the right place, U-1 means you need our standard EVO 614 pair.
We fit the 614HD with MK Powered batteries in two versions and nothing else. The M22NF SLD A is a 12 volt, 55 amp hour sealed AGM battery and the standard choice, delivering the most capacity per charge. The M22NF SLD G is a 12 volt, 51 amp hour gel battery, and while its amp hour number reads lower, gel is the tougher chemistry: it handles deep discharges more gracefully, tolerates heat and cold better, and typically delivers more usable cycles over its life. On a chair carrying 450 pounds every day, that durability often outweighs the small capacity difference.
MK has supplied the leading wheelchair and power chair manufacturers for decades, and both options are sealed, completely maintenance free, and spillproof, so there is no water to add and no risk of a spill on carpet or in a vehicle. There is no wrong answer between them, only the one that better matches how hard you use your chair and where you store it.
Your batteries ship partially charged, which is standard for safe transport, so give them a full overnight charge before your first outing, then charge daily for the first two weeks while the new pair breaks in. Shipping is free, your order leaves our warehouse within three business days, and real people answer our phone whenever you have a question.
