Each battery is identified with a unique serial number label and indelibly marked

for future reference.

INSPECTION FOR SHIPPING DAMAGE
4.2.1
Upon receipt, the packages must be examined for any shipping damage before
they are placed in storage or use. If any damage is noted, contact the shipping
company immediately.
4.2.2
Type verification can be performed by checking the serial number label on the

Compliance.
4.3
STORAGE REQUIREMENTS
4.3.1
TBPs 7000 series LT VRLA batteries can be stored between -20°F (-29°C) and
+110°F (43°C). Ideal battery storage temperature is 80°F (27°C). Storage at
temperatures other than these, can lead to permanent damage.
Storage temperatures will determine inspection requirements. These requirements
are identified under this section.
4.3.2
TBPs 7000 series LT VRLA batteries have a maximum of 24 months of
inspection-free storage life, IF stored at temperatures between 40°F (4°C) to 80°F
(27°F).
4.3.3
If stored between 95°F (35°C) to 110°F (43°C), the battery must be inspected on a
monthly basis. It is not recommended to store any VRLA batteries at these
temperatures for excessive periods of time (maximum 3 months storage).
Prolonged storage at high temperatures (over 110°F or 43°C) will reduce battery
life due to various deleterious reaction mechanisms at higher temperatures.
During these monthly inspections, the battery must be recharged per Section 5.2
and returned to storage. If the storage period has exceeded the time
recommended in this section, contact Teledyne Battery Products for disposition.
4.3.4
All batteries returned from service after initial use must be fully charged per
Section 5.2 and stored. The storage start date and battery voltage must be
