Your Sparrow will not have a 40 to 60-mile (64.4 to 96.6-kilometer) range
in the beginning. The
battery pack on your new Sparrow needs to be broken in.
The battery pack is broken in during the first 50 cycles. (A
cycle is the
complete battery discharge and subsequent charge to full capacity.) The battery
pack increases its performance up to the 50th cycle. It reaches its maximum
performance at that point, then begins to slowly deteriorate. The typical cycle
life of a battery pack that is discharged below 30 percent is approximately 300
cycles. When batteries are not discharged below 50 percent, battery life can
reach up to 500 cycles.
