Lucent Technologies Round Cell Batteries
6 - 18 Installation Issue 3 December 1999
Initial Charging, continued
Maximum Time
Allowable Until
Initial Charge
The Round Cell is shipped charged and wet. A charged and wet cell
should not stand on open circuit for more than 6 months at 77°F. The
“charge by” date stamped on the shipping container is that date when the
cells will be on open circuit for 6 months.
To maintain the battery until the normal charge can be administered, do
one of the following:
• Keep the battery on continuous float charge at 2.17-2.20V/cell.
• Charge at 2.17-2.20V/cell, 8 hours a day, 5 days a week.
• Give a boost charge at 2.5 to 2.55 volts for 8 hours every 6 to 8
weeks until the normal initial charge can be administered.
Notes
• If the storage temperature exceeds 90°F (32°C), the open circuit
time should not exceed 4 months.
• If the initial charge cannot be given within 6 months, unpack the
battery following the appropriate procedures in the “Unpacking and
Handling” section. If the batteries are to be shipped to another
location later, keep and reuse the packaging to properly prepare the
battery for shipping.
DANGER
• Batteries must only be charged with vent funnel installed.
• Only qualified trained personnel that have read and understand the
hazards described in the safety section of this manual should
perform this work.
