- Sterling S400 mobility scooter battery set
The Sterling S400 takes a pair of 12v sealed lead AGM batteries; they connect together to create a 24V pack within the mobility scooter. Changing them is relatively easy, but they are heavy. First, remove the seat. Use the lever to unlock, turn it a quarter turn, then use the recline lever to lift the armrests and push the seat back down. You can now lift the whole seat assembly straight up and off. Now it's just the casing: three winged bolts, one at the front, two at the rear, and it will lift off, exposing the batteries. Change one at a time so you don't confuse the cables; it's a quick job that takes no longer than a few minutes, but as mentioned, the batteries are heavy.
Charge your new Sterling S400 batteries when they arrive before using them for the first time. It will take about ten charges and normal use of the scooter before they can take a full charge; this is normal conditioning for any rechargeable battery. If, for whatever reason, they are not being used, then recharge every four weeks. Also, after every use, it's best to keep at least 80% capacity in it at all times. If you regularly take it below 50%, it will negatively affect the overall lifespan of the batteries.
