Power Supply Module and Backup Battery
3-16
Motorola battery warranty is valid only when the battery is charged with the original
Motorola ACE3600 charging power supplies. Use of any other power supply/charger
will void the battery warranty.
Under various state or local laws, the batteries must be recycled or disposed of
properly and cannot be disposed of in landfills or incinerators. Environmental
protection regulations classify used Lead Acid batteries as hazardous waste, unless
certain exemptions apply. Consideration should be given to the methods of collecting,
labeling, handling and shipping used Lead Acid batteries. Please consult the
environmental protection authority for specific legal requirements and for recycling
options in your country/area.
Backup Battery Storage, Lifespan, Inspection and Replacement
The manufacturer’s recommendations for handling during each of the battery’s life stages are:
•
Transportation:
Batteries must be handled with care to prevent falls, impact, short circuit or exposure
to high temperatures and fire.
•
Battery Storage:
Storage of batteries in a warehouse requires a periodic recharge. The time between
these recharge cycles depends upon the storage temperature. The minimum open
circuit voltage allowed on the battery before recharging is 12.42 V, which represents
remaining capacity of approximately 30%. Therefore it is recommended to perform a
full charging cycle every few months depending upon the storage temperature of the
battery. Please refer to Table 3-1 to determine the suggested maximal period between
recharge cycles that suits the actual storage conditions. Improper storage may cause
deep discharge of the battery, which might cause degradation of the battery operating
life and lower the actual delivered capacity. Motorola performs a periodic full charge
cycle procedure on stored batteries and a final full charge operation prior to shipment.
•
Lifespan:
The average temperature of the battery environment affects the lifespan of batteries
installed in the field. Please refer to the battery vendor information at the following
website:

•
Inspection and Replacement:
It is important to inspect the batteries periodically (recommended every 6-12 month)
and replace any battery that has corrosion on the leads or it is deformed or leaks. Such
a battery should be disposed according to the local environmental laws. To assure the
battery availability and proper operation, the battery should be replaced at the end of
its lifespan (approximately 30% capacity) even if it is still functional. Measure the
battery open circuit voltage using a digital voltmeter as described above. Please note
