Big-capacity batteries for long days out on a larger scooter or chair

Larger road scooters and outdoor electric wheelchairs work hard, and their batteries carry a lot of weight up hills and over long distances. When yours no longer hold their charge the way they did, a new pair of 50 Ah MK AGM batteries gives you back the stamina for longer trips, steeper routes and full days away from home.

The MK batteries are sealed and completely maintenance-free. From years of fitting them, we've found MK to be one of the most dependable makes for long life, as long as they're charged after each use.

✅ Key Features & Benefits

• Large 50 Ah capacity
  Made for bigger scooters and chairs that need plenty of power, so hills and longer outings don't drain you before you're home.

• A pair, ready to fit together
  Fitting two new batteries at once keeps them evenly matched for steady performance and a longer working life.

• Zero maintenance
  Sealed AGM batteries never need topping up or checking, so there's one less job to worry about at home.

• Spill-proof construction
  The electrolyte is fully absorbed inside, so there's no risk of acid leaking onto your floor or into your scooter.

• Resists vibration damage
  Strengthened posts, straps and welds are built for the knocks and judders of everyday outdoor use.

• Keeps its charge in storage
  Less than 2% loss a month, handy if your scooter is put away over winter or between holidays.

Who it suits best

• Owners of larger road scooters that take 50 Ah batteries
• Electric wheelchair users who travel outdoors a lot
• Anyone tackling hills or long distances regularly

Worth knowing before you buy

50 Ah batteries are physically bigger and heavier than smaller sizes, so they only suit scooters and chairs designed to take them. They won't fit a small boot scooter. Please check your current batteries' rating or ask us before ordering. As with any lead-acid battery, letting them run completely flat or sit uncharged for long periods shortens their life.

Questions customers ask us

My scooter has 55 Ah batteries. Can I use these?
Battery sizes aren't always interchangeable. Tell us your make and model and we'll confirm the right batteries before you buy.

What's the best way to charge them?
Charge overnight, for a minimum of 8 hours, after each day of use. Regular charging is what keeps them going for longer.
