Specifications — Each Battery

Why Voltage Matching Matters

When your scooter or power chair runs on two batteries, mismatched voltages cause one battery to work harder than the other — leading to uneven wear, reduced range, and premature failure of both batteries. The MK M17-12 SLD M is sold as a voltage-matched set, meaning both batteries are tested and confirmed to operate at the same voltage from the factory. This extends the life of both batteries and protects your equipment's motor and charging system.

• Voltage matched — both batteries confirmed at the same output level
• Lead calcium construction — lower self-discharge, longer shelf life
• Tank formed plates — consistent cell performance across the battery life
• Rugged compact design — vibration resistant for outdoor terrain
• Float or cycle use — works in both standby and daily discharge applications
• FAA, IATA and UPS approved — safe for air and public transport

Taking Your Scooter on the Road?

With FAA and IATA approval, the MK M17-12 SLD M travels easily — but getting your mobility equipment to your destination safely starts with how you transport it. A vehicle lift protects your scooter during loading, unloading, and transit, and takes the physical strain completely out of the process. See our Harmar Vehicle Lift Guide 2026 to find the right lift for your vehicle and scooter — and travel with total confidence.
