SECTION 2 - STORAGE and SHELF LIFE
2.1 Storage of VRLA (valve regulated lead acid) Batteries
Store batteries indoors, preferably at 77°F (25°C) or in a cool 20°F to
90°F (-7°C to 32°C), dry location and place on charge by the
date
found on the battery carton.
Note: Batteries that are not placed in service for several months will
self-discharge.
Storage time is based on storage at 77°F (25°C) and is six months for
Liberty Series 1000 valve regulated cells. Do not allow the electrolyte
to freeze, as this will destroy the battery and can cause a potentially
hazardous condition and leakage.
Refer to Table 1, for electrolyte freezing temperatures. Although the
specific gravity of a fully charged battery may present no freezing
problem, a discharged battery gravity may freeze at relatively mild
temperatures.
