Magliner Powered Stair Climber User Maintenance Manual page 6

Test the battery pack for voltage with a MultiMeter or similar. A good battery should
read 24-26 volts (VDC). If the MultiMeter reads 12-15 volts (VDC), one battery cell
needs replacing. Check each cell separately to determine which battery cell needs
replacing.
To replace battery cells, remove battery cover with a #1 Phillips screwdriver. Remove
fuse and unplug top wires and tilt entire battery case 45 degrees to allow cells to gently
fall out of case. Unplug bottom wires.
!
Caution !
Avoid touching battery contact points together.
Reconnect bottom wires into the new battery cells. Gently reposition into the battery
case and reconnect the top wires. Use page 33 as a guide when reconnecting.
!
Caution !
Inserting a battery with reversed polarity on the Powered Stair Climber will cause
a short circuit in the electronic card and may cause overheating and potential
damage to the DC charger.
Before inserting this battery on your Powered Stair Climber, test the battery for reverse
polarity by connecting your battery to a charger. Display will alternately blink
symbols to indicate reversed polarity. Correct polarity by ensuring the battery wires are
connected exactly as shown on page 33.
