Your Pride Jazzy EVO 613 solves a problem most full size power chairs never manage: it fits. At just 22 inches wide at the base with a 22 inch turning radius, it moves through narrow hallways, small bathrooms, and standard doorways that stop wider chairs cold. Mid-Wheel 6 technology centers the drive wheels under the seat, Active-Trac suspension smooths out thresholds and sidewalk cracks, and it still reaches 5.1 mph outdoors. Two 12 volt U1 batteries power all of it as a 24 volt pair.
Before you order, confirm which EVO you have. The Jazzy EVO 613 uses two U1 lead acid batteries, and this pair is built for it. The Jazzy EVO 613Li uses a single lithium iron phosphate battery instead, and these will not fit that chair. The two models look nearly identical and are sold side by side, so check your battery compartment: if you see two batteries, you have the 613 and you are in the right place.
We fit the EVO 613 with MK Powered U1 batteries in two versions, and here is what makes this choice simpler than most: both are rated 12 volt, 31.6 amp hours, so 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 daily. 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. At roughly 23.5 pounds each, U1 batteries are also considerably easier to handle than the Group 22NF and Group 24 batteries larger chairs use, so most people manage this swap without help.
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.
