The UCH0053/UCH0054 Battery Charger/Conditioner are designed to provide a safe and effective recharge of the
following batteries:
UBI-2590 Li-Ion
UBBL35 Li-Ion
BB-2590/U Li-Ion
UBBL06-xx Li-Ion
PRC-148 Li-Ion
UBBL08-xx Li-Ion
PRC-152 Li-Ion
BB-590/U Ni-Cd
BB-390/U Ni-MH
PRC-154 Li-ion
These batteries are rechargeable batteries commonly used with Tactical Communication Equipment. Some batteries
have the same form factor and in many cases are interchangeable for battery operated equipment. The
UCH0053/UCH0054 charger has two options for charging batteries; internal and external. Internal refers to the ability
of the user to place either two 2590 type batteries or four radio handheld batteries at one time into each bay. External
charging refers to the ability of the user to charge UBBL35, UBBL08, UBBL06 or similar batteries using external
charging cables supplied by Ultralife. Optional battery adapters can be placed in the 2590 charge bays to charge
additional batteries. In the event that the user connects batteries to a single bay via both the internal and external
methods, priority for charge will be given on a first-come, first-serve basis.
CAUTION:
Prior to using the UCH0053/UCH0054 charger please read the safety and caution
instructions located in section 1 to prevent the mischarge or catastrophic destruction of a battery.
While inherently safe, misuse of the UCH0053/UCH0054 charger may result in damage to the
battery and/or the UCH0053/UCH0054 battery charger.
2.1
Charge Safety
The UCH0053/UCH0054 charger will detect 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 charge cycle. Charge is terminated when the unit detects the battery has been fully charged.
In the case of xx90 style batteries, the UCH0053/UCH0054 charger will detect the chemistry type through
the presence of the top contacts. In no event will a battery be overcharged using the charging algorithm of
the UCH0053/UCH0054.
2.2
xx90 Battery Detection
The charger detects the presence of a non-smart xx90 battery using the circular connector and the presence
of a short on the thermistor contacts located on the top of the battery. When a 2590-type battery is
detected, the charger will charge using a constant current of 3.0A until the charge current falls below
100mA, at which time the charge is terminated. In the event the current does not fall below 100mA within
12 hours, the UCH0053/UCH0054 charger will terminate the charge for that battery. With the absence of a
short on the thermistor contacts on top of the battery, the UCH0053/UCH0054 charger will assume that
the battery is a Nickel-based chemistry (Ni-Cd or Ni-MH). The charger will charge at a constant current of
480mA until the total charge time reaches 12 hours. For a Ni-MH battery, the charger is able to measure
the internal battery temperature using the top thermistor contacts.
