Tips: A new battery will only be partially charged and will require a full charge prior to use.
Battery Maintenance: 1.Always remove battery from your vacuum when you are assembling parts, making adjustments, cleaning or when not being used for an extended time. 2.If you don't plan on using the battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. During storage, remember to recharge the batteries before use. 3.Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks.
