Replacing
a Faulty BBU
trigger the BBU fault LED:
1.
The temperature sensor embedded with the charger circuit
reports a temperature reading exceeding the preset threshold.
The charger circuits will enter a low-power and self-protection
state.
2.
A BBU module has been charged for over twelve (12) hours. A
timer is embedded with the charger. When this occurs, the
charger will enter a timer fault state. The fault condition usually
occurs with a brand new BBU or with a totally discharged BBU.
Charging will resume automatically if your remove and then re-
install the BBU.
BBU Warnings and Precautions:
Install or replace the BBU with BBU’s supplied by your Galaxy
vendors only. Use of battery cells provided otherwise will void our
warranty.
Always dispose of a replaced battery in an ecologically responsible
manner. Dispose of used BBU’s at authorized battery disposal sites
only.
Do not use nor leave the BBU near a heat source. Heat can melt the
insulation and damage other safety features of battery cells, possibly
will cause acid leak and result in flames or explosion.
Do not immerse the BBU in water nor allow it to get wet. Its protective
features can be damaged. Abnormal chemical reactions may occur,
possibly will cause functional defects, acid leak, and other hazardous
results.
Do not disassemble or modify the BBU. If disassembled, the BBU
could leak acid, overheat, emit smoke, burst and/or ignite.
Do not pierce the BBU with a sharp object, strike it with a hammer,
step on it, or throw it. These actions could damage or deform it and
internal short-circuiting can occur, possibly will cause functional
defects, acid leak, and other hazardous results.
If a BBU leaks, gives off a bad odor, generates heat, becomes
discolored or deformed, or in any way appears abnormal during use,
recharging or storage, immediately remove it from the subsystem and
stop using it. If this is discovered when you first use the BBU, return it
to your subsystem vendor.
