Your Pride Jazzy Select has kept a lot of people moving through a lot of ordinary days. A 22.5 inch turning radius takes it through standard doorways, around furniture, and down narrow hallways without a three point turn, while Active-Trac Suspension and an articulating rear caster beam smooth out the cracked sidewalk on the way to the coffee shop. Two 12 volt U1 batteries power all of it as a 24 volt pair, and after 12 to 24 months of daily use they wear down. Range falls off well short of the rated distance, the chair feels slower off the line, and charges stop lasting the day.
We fit the Select with MK Powered U1 batteries in two versions, and here is what makes this decision simpler than most: both are rated 12 volt, 31.6 amp hours. You are not trading capacity for anything. The MU-1 SLD A is the sealed AGM version and the everyday choice for most riders. The MU-1 SLD G is the gel version, and gel handles deep discharges more gracefully and tolerates heat and cold better, which matters if your chair lives in an unconditioned garage, a hot climate, or gets run down hard every single day. Same range either way, different toughness.
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. Whichever you choose, you are getting the same battery brand the chair manufacturers themselves specify.
The Select makes this job easier than most full size power chairs. Its batteries are accessible from the sides of the power base, so you are not lifting the seat off or working blind under a shroud. Most people finish in about 20 minutes: open the side access, note which cable connects to which terminal, exchange the old pair for the new one matching red to positive and black to negative, and close it back up using your existing cables and hardware.
Your batteries ship partially charged, which is standard for safe transport. Pride recommends charging new batteries for 8 to 14 hours before first use, then charging daily for about two weeks, because a new pair needs a break in period to reach its full range. Slightly short early rides are normal and not a sign of a problem. After that, charging after every use and never leaving the chair sitting discharged is what gets you to the longer end of the lifespan. Shipping is free, your order leaves our warehouse within three business days, and real people answer our phone whenever you have a question.
