ACTIVATOR 50 CHARGER USER’S GUIDE

• Be sure to fully understand the information for the battery to be charged or
discharged. If the programming values are incorrect, the battery can be severely
damaged. Incorrect charging of Lithium batteries can cause a fire or explosion.
• Never charge a Lithium battery that is swollen in any way.
• To avoid short-circuits between the output power adapter cord connectors,
always connect the adapter cord to the charger first and only then to the battery to
be charged or discharged. Reverse the sequence when disconnecting.
• Carefully verify the capacity and voltage of your Lithium battery before charging
or discharging it. It may be composed of mixed parallel and series connected
cells. In parallel, the capacity of the battery is multiplied by the number of cells
in parallel (2P means x2), but the voltage remains the same. The voltage
imbalance possible in parallel packs can cause a fire or explosion during the
charging process.
We recommend using Lithium batteries in series cell
format only.
