Your Pride Jazzy Air 2 does something almost no other power chair does: it lifts you 12 inches in 11 seconds, and it keeps driving at full speed while elevated. That means conversations at eye level, reaching the upper shelf at the supermarket, and working at a countertop instead of around it. Mid-Wheel 6 drive and Active-Trac suspension handle the rest, indoors and out. All of it runs on two 12 volt batteries wired as a 24 volt pair, and the elevation motor draws from that same pair every time you rise.
Pride builds the Air 2 with standard U1 batteries and offers a 40Ah class upgrade, and the upgrade is what we stock. The MK M40-12 SLD M is a 12 volt, 45 amp hour sealed AGM battery with the highest capacity of the two. The MK M40-12 SLD G is a 12 volt, 40 amp hour gel battery, and although its amp hour number reads lower, gel handles deep discharges more gracefully, tolerates heat and cold better, and typically delivers more usable cycles over its life. Either way, you move up from the standard U1 range of about 16.8 miles to roughly 19.2 miles per charge.
That extra capacity matters more on this chair than on most, because every elevation cycle costs energy. Riders who use the lift throughout the day, at the kitchen counter, at the table, at the store, notice their range shrinking faster than the spec sheet suggests. A larger pair gives you the headroom to use the feature you paid for without watching the gauge.
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. 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. Pride specifically notes that new batteries need this break in period to reach their optimal range, so slightly short early rides are normal.
