Get your scooter's distance back with a dependable new set of batteries

Batteries wear out gradually, so it's easy not to notice until a trip you used to do easily suddenly feels risky. If your mid-sized scooter or electric wheelchair takes 35 Ah batteries, this pair of MK AGM batteries puts the range back where it should be, so you can plan a full day out again without worrying about getting home.

They're sealed, spill-proof and need no maintenance. MK is the battery brand our engineers rate highly for reliability and lifespan, provided the batteries are charged regularly.

✅ Key Features & Benefits

• Restores lost range
  New batteries mean you can go to the shops, call on a friend and get home again without watching the gauge every few minutes.

• Two batteries, replaced together
  Changing both at the same time keeps them balanced, so neither one drags the other down and they last longer.

• Nothing to top up
  Sealed AGM (absorbed glass mat) construction means no water, no acid checks and no mess, which is a relief if bending or fiddly tasks are difficult.

• Leak-proof if knocked
  The electrolyte is held in the glass mat, so there's nothing to slosh or spill.

• Tough inside
  Reinforced posts and welds stand up to the constant vibration of pavements, kerbs and uneven paths.

• Slow to lose charge
  Under 2% self-discharge a month, so a scooter that sits for a week or two still has power when you need it.

Who it suits best

• Mid-sized scooters and electric wheelchairs that take 35 Ah batteries
• Riders who've noticed their range getting shorter
• Anyone who wants low-maintenance batteries

Worth knowing before you buy

Always replace batteries with the same size and amp-hour rating your scooter or chair was built for. A smaller battery may not fit the tray properly, and a larger one may not fit at all. If you're not sure, check the label on your old batteries or ask us. These batteries last longest when they're charged after every use, rather than run flat.

Questions customers ask us

Do I need to replace both batteries?
Yes, we recommend it. An old battery paired with a new one wears the new one out faster and you won't get the full range back.

How long should I charge them for?
Put your scooter or chair on charge overnight, for at least 8 hours, each day you've used it.
