SimplyGo Mini Desktop Charger
The Smart Battery Charger is a great option for people who have extra concentrator batteries as it allows all batteries to be rotated and kept fully charged at all times.
The Smart Battery Charger will recharge one battery at a time as well as recalibrate the battery's fuel gauge. Fuel gauge recalibration enables the battery to calculate a highly accurate estimate of remaining battery life, shown on the battery fuel gauge, even as the battery ages.
