2 PRODUCT DESCRIPTION
The CH0003 Battery Charger/Conditioner is designed to provide a safe and effective recharge of the
following batteries:
 BB-390/U / MAI-390 Nickel Metal Hydride
 BB-590/U / MAI-590 Nickel Cadmium
 BB-2590/U Lithium-ion
 UBI-2590 Lithium-ion
 UBBL09 Lithium-ion
These batteries are rechargeable batteries commonly used with Tactical Communication Equipment.
Each battery has the same form factor and in many cases is interchangeable for battery operated
equipment. The CH0003 will charge up to six batteries at one time. Additionally, the user can charge
multiple battery types at the same time.
CAUTION: Prior to using the CH0003, please read the safety and caution
instructions located in section 1 to prevent the mischarge or catastrophic
destruction of a battery.
While inherently safe, if the CH0003 is used incorrectly, an accident
can occur. Misuse of the CH0003 may result in damage to the battery and/or the
CH0003 battery charger.
2.1 Features
CH0003 features are described in the following subsections.
2.1.1 Charge Detection
The CH0003 automatically detects battery problems such as open cells or other battery problems,
which prevent a safe and efficient charge. There are a number of internal safeguards built into the
unit. Temperature, voltage and time are monitored throughout the fast charge. Fast charge is
terminated when the unit detects the battery has been fully charged. The CH0003 also automatically
detects different battery chemistries by the contacts or lack of contacts on the battery itself.
2.1.2 Lithium Ion Battery Detection
The charger detects the BB-2590 Li-Ion battery through the contact on the battery. When it is
detected, the charger will charge using a constant current of 1.0A until the voltage reaches 16.4V.
When the voltage is reached, the charger will go into a constant voltage mode. When the charge
current falls below 140mA, the charge is complete. There is a 12-hour safety timer if the charge
current never goes low enough. This will terminate the charge.
