MK wheelchair chargers

Why use a dedicated MK charger

An MK GEL 8G24, 8G27, 8G31 or 8G8DLTP battery needs a specific charging profile — lower absorption voltage and a slower curve — that a generic lead-acid charger does not apply. Using the wrong power wheelchair charger halves the GEL battery service life. MK chargers are factory-calibrated for mobility GEL/AGM and are the recommended choice for most wheelchair and scooter makers.

Which MK charger to choose

• MK Charger 24V 5A — small-mid mobility scooter.
• MK Charger 24V 8A — standard wheelchair, 8G24/8G27 batteries.
• MK Charger 24V 10A — large or bariatric wheelchair, 8G31/8G8DLTP batteries.

How to look after your wheelchair battery

• Charge the chair every night, even if not fully discharged: GEL prefers frequent partial cycles over occasional deep discharges.
• If the chair sits idle for more than a week, leave it plugged in: the MK charger drops to float mode automatically without overcharging.
• Replace the battery once autonomy falls below 70% of nominal.

Frequently asked questions about MK chargers

What amperage do I need for my wheelchair?

It depends on size: 5A for a small-mid scooter, 8A for a standard wheelchair (8G24/8G27) and 10A for a large or bariatric wheelchair (8G31/8G8DLTP).

Does it work with AGM and GEL batteries?

Yes, MK chargers are factory-calibrated specifically for the mobility GEL/AGM profile, with the absorption voltage and curve suited to this battery type.

What is the difference versus a generic lead-acid charger?

The MK charger applies a lower absorption voltage and a slower charging curve, matched to GEL chemistry; a generic charger can overcharge and halve the battery service life.

How often should I charge the wheelchair?

Ideally every night, even if it has not fully discharged. If the chair will sit idle for more than a week, it is best to leave it plugged into the MK charger.
