Description
The MK 8A22NF battery is a 12 V group 22NF sealed AGM cell for mobility scooters and power chairs. Westin Healthcare sells it, delivers it, and can swap it in Brampton and the Greater Toronto Area. Current MK naming prints 55 Ah at the 20-hour rate. The AGM brochure still prints 46.5 Ah at the 5-hour rate. Most of those devices run two 12 V batteries in series for 24 V, so you usually buy two and replace both at the same time.
Who this battery is for
This is the sealed AGM 22NF, not the gel 8G22NF. Quantum Rehab names MK AGM on several NF-22 bases, including the Edge 3, the Q6 Edge 2.0, and the Stretto. It is not the factory size for a Baja Wrangler 2, and it is not a U1 travel-scooter cell.
Bring the old battery or a photo of the group stamp and the terminals. We match AGM to AGM before we send a pair. Call (905) 451-7743 if you are not sure.
MK 8A22NF battery chemistry and pairs
MK prints the 8A22NF as AGM (M22NF SLD A), not gel. East Penn rates the 8A family non-spillable by DOT, ICAO, and IATA definitions. AGM usually charges on a standard sealed-lead profile. Gel is a different charger setting. Do not mix one AGM and one gel in the same 24 V pair.
Quantum and Interstate both describe typical mobility systems as two 12 V deep-cycle batteries in series. Westin sells the 8A22NF as a single 12 V battery. Order two when the device takes a pair.

AGM, gel, or Interstate: which 22NF sibling fits
Stay on AGM if the old cell is AGM. If the old cell is gel, see the MK 8G22NF. Interstate's mobility 55 Ah 22NF is the DCM0055. Interstate gel in this footprint is the GEL0055 at 50 Ah. A U1 tray takes the MK 8AU1.
Delivery and setup in Brampton and the GTA
Westin's own team delivers this battery across Brampton and the Greater Toronto Area. When you want the pair swapped at home, we lift the seat or the deck, fit the new pair, and take the old cells for recycle. Book that swap on the battery replacement page or by calling (905) 451-7743.
We have three stores in the Brampton and Toronto area if you would rather bring the old 22NF in. Same-day replacement is offered on that battery replacement service; purchased batteries that ship without a technician are delivered on a scheduled date.
Each cell is about 38 lb. If the order is going outside the GTA, ask us for a shipping quote. Inside Toronto and the GTA, White-Glove Delivery (bring-in, unwrap, test, take packaging away) is described on the shipping policy. Any charge is confirmed on your order.
