Conditioning
Also known as discharging a battery pack to one volt per cell (minimum voltage a single cell should be
discharged) to ensure battery pack will maintain its recommended capacity and extend the life of the
battery. It is recommended to condition a NiCD battery before every charge, and periodically for NiMH,
except when new. All new NiMH batteries need a "wake up" period. It is important to cycle (discharge
and charge) new packs 3-5 times so it can hold a full charge. Note that conditioning is not required, but
highly recommended for the life of your battery pack.
1) Supply power to unit with 18v wall adapter when 110v AC is available or 12v cigarette lighter
adapter for use in your vehicle.
2) Locate the charge contacts on the battery pack.
Note: Many battery packs have more than two contacts (see on next page). The correct contacts to use
can be found in two ways: use of a digital multimeter or trial and error. It is most convenient if you have
a digital multimeter that you can use to find the correct contacts (positive and negative). But if you do
not have a digital multimeter, you can use your rapid charger to find the correct positive and negative
contacts. The charger has built in protection and a reverse polarity switch so trial and error method will
not damage the battery pack or the rapid charger. Also note that some battery packs are equipped with
diode protection and make it impossible to discharge using charging contacts. In this situation it is
recommended to use the other contacts designed to power the electronic device. Please feel free to call
tech support for help if this is a problem.
