Storage
It is recommended that the fully charged battery should be stored in a cool dry
place, ideally below 25
°
C (77
°
F). The battery charge retention will be reduced
with increased temperature.
The graph in Figure 6 demonstrates typical capacity retention of the battery
during storage without regular boost charges.

The battery may be stored up to 5 years without degradation of performance
provided that an inspection and open circuit voltage check is conducted every
12 months. When stored in temperatures in excess of 35°C (95°F), the
battery should be inspected every 6 months. If the Open-circuit Voltage falls
below 25.3V the battery should be charged in accordance with Section 4. E.
