The LED Indicators
Once the battery has been inserted into the Mach 1, the LED above it will
indicate the status of the battery being charged. The Mach 1 contains an
internal cooling fan which will run continuously as long as there is at least one
battery being charged on the unit.
LED On – The battery at that location is being “Speed charged”. Once the
LED turns Off, the battery at that location has completed “Speed charging”
and is trickle charged for the next 2-3 hours. The cell is now ready for use, but
may be left in the charger during the trickle charge to achieve a completely
full charge.
LED Flashing - If an indicator LED is flashing above one or more of the cells
being charged, this is an indication of an ERROR condition. The battery
below the flashing LED is either faulty or at the end of it’s life and should be
replaced, as it is no longer useable.
LED does not turn on – If the LED will not come on after a cell is inserted at
that location, the voltage of that battery has dropped to a very unhealthy low
level. The battery should be replaced.
The battery cell(s) being charged may be safely removed at any time without
harm to the cell or the charger unit. Once charging is complete, promptly
remove the cell(s) and unplug the Mach 1 charger.
Notes:
• This Mach 1 charger is designed for use with NiMH (Nickel Metal-
Hydride) AA and AAA cells only. Do not charge NiCd (Nickel
Cadmium) or any type of cells other than NiMH in this charger.
• The Mach 1 charger unit is designed for use in normal room temperature
environments. In cases where the air temperature may rise near or above
85° F, the internal microprocessor will adjust the rate of charge to assure
the safe charging of the cells, resulting in increased charge times.
• It is normal for the charger, AC adapter, or the battery cells to become
warm during charging.
• Do not install a AAA cell and a AA cell into any one charging location
at the same time.
• Batteries will self discharge when not in use. Batteries can be kept fresh
if you recharge them every 2-3 months.
Approximate Charge times*
700 mAh AAA 30 minutes
1600 mAh AA 55 minutes
1800 mAh AA 60 minutes
2000 mAh AA 65 minutes
*Actual charge times will vary depending on the cell’s discharge level,
capacity and condition. Longer charge times will occur when this charger is
used in temperatures above 85° F.
Trouble Shooting Tips:
• Batteries should be replaced when run time becomes short.
• If the LED status indicator does not light up when the charger unit is
properly plugged into a power source, and a discharged battery is
correctly installed, make sure that the AC socket or cigarette lighter has
power and that the battery cell is not defective.
• Use a clean dry cloth when necessary to keep the metal contacts of both
charger and battery clean.
Cautions:
• For use with AA and AAA size NiMH batteries ONLY! Use with other
type batteries voids warranty, may cause damage to the charger/ battery
and possibly cause injury to the user.
• Do not leave any battery cell connected to the charger for prolonged
periods. Remove the battery promptly after charge is complete.
• Unplug the charger when not in use.
• Do not use, place or store the charger where it may come into contact
with water or moisture.
• Always replace frayed or damaged wire and broken plugs immediately.
• Use this charger with the power adapters included in the package only.
• No user serviceable parts, opening chassis will void warranty.
• Charger needs proper ventilation. Make sure charger vents are not being
blocked and there is no problem with circulation
• Do not use if charger fan is not operating.
• Charge only NiMH batteries on this charger.
• Batteries are not charged as shipped. Must be charged prior to first use.
