The GMI Smart Charger provides both fast and standard
charging facilities and can charge an instrument and spare
battery pack simultaneously. Using the standard charging
option, a battery pack can be recharged in 12 hours from
a fully discharged state. Using the fast charge option a
battery pack can be 90% recharged in approximately 60
minutes and fully recharged in 120 minutes. To ensure
optimum life length, the rechargeable pack should be fully
discharged and charged on a regular basis of, at least,
every three months. The Smart Charger has the option of
switching to discharge and fast charge cycle to provide
this facility.
