A
Never place a charger on a car seat, carpet or similar surface. Keep all flammable volatile materials away
from the operating area.
A
Make sure you know the specifications of the battery to be charged or discharged to ensure it meets the
requirements of this charger. If the program is set up incorrectly, the battery and charger can be damaged.
A
Fire or explosion can occur due to overcharging.
A
To avoid a short circuit between the charge lead, always connect the charge cable to the charger first, then
connect the battery. Reverse the sequence when disconnecting.
A
Never attempt to charge or discharge the following types of batteries:
•
A battery fitted with an integral charge circuit or a protection circuit
•
A battery pack which consists of different types of cells (including different manufacturer’s cells)
•
A battery that is already fully charged or just slightly discharged and non-rechargeable batteries (these
pose an explosion hazard)
•
A faulty or damaged battery
•
Batteries installed in a device or which are electrically linked to other components
•
Batteries that are not expressly stated by the manufacturer to be suitable for the currents the charger
delivers during the charge process.
PLEASE BEAR IN MIND THE FOLLOWING POINTS BEFORE YOU COMMENCE CHARGING:
•
Did you select the appropriate program suitable for the type of battery you are charging?
•
Did you set up the adequate current for charging or discharging?
•
Have you checked the battery voltage? Lithium battery packs can be wired in parallel and in series, i.e. a
2-cell pack can be 3.7V (in parallel) or 7.4V (in series).
•
Have you checked that all connections are firm and secure?
•
Make sure there are no intermittent contacts at any point in the circuit.

WHEN ADJUSTING YOUR POWERPEAK D7 CHARGING PARAMETERS, BE SURE YOU SELECT
THE PROPER BATTERY TYPE AND CELL VOLTAGE FOR THE TYPE OF CELL YOU ARE CHARGING.
CHARGING BATTERIES WITH THE WRONG SETTINGS MAY CAUSE THE CELLS TO BURST, CATCH
FIRE OR EXPLODE.
