The typical operation time of 6 years is based on only 80% battery capacity and an operation
time/temperature profile of 5% at 0 °C (32 °F), 80% at 15 °C (59 °F) and 15% at 50 °C (122
°F).
The effect of other temperatures is shown in the figure below.
A variation in temperature from 15 °C to 55 °C (59 °F to 131 °F) reduces the capacity by
17% (in the figure from 15 Ah to 12½ Ah).

Note
The installation orientation of the battery pack may influence the battery capacity. Optimal
battery capacity is achieved with the battery pack in an upright position.
