Maintain the Battery Chapter 10
Store Lithium Batteries
• You may store batteries for up to 30 days between -45…85 °C
(-49…185 °F) such as during transportation. Do not store in temperatures
above 85° C (185 °F).
• To avoid leakage or other hazards, do not store batteries above 60° C for
more than 30 days.
• The rate of capacity loss increases as storage temperature increases.
Battery Removal
ATTENTION: Follow these general rules to store your batteries.
• Store batteries in a cool, dry environment. We recommend 25 °C (77 °F)
with 40…60% relative humidity.
• Regularly monitor the temperature and humidity of the storage area.
• Use a first-in/first-out system for handling stored batteries.
• Store in the original containers away from flammable materials.
• Keep track of storage time. Reference storage time to the date of
manufacture.
• Do not store batteries longer than 10 years.
• Do not store used batteries longer than 3 months before disposal.
• Clearly mark the contents of the storage area.
• Place a Lith-X or Class D Powder fire extinguisher in a readily accessible
area in or around the storage area.
• Ventilate and protect the storage area against fire. You must have a
system that automatically detects and extinguishes fires and
automatically activates an alarm signal.
• Do not smoke in the storage area.
Table 33 - Storage Temperatures for 1769-BA Lithium Batteries
Storage Temperature Capacity Loss
40 °C (104 °F) for 5 years Loses up to 4% of original capacity
60 °C (140 °F) Loses 2.5 % of capacity each year
WARNING: When you connect or disconnect the battery, an electrical
arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.
