Caution
Following example shows the life calculation of the back-up battery used in assumed ro-
bot operation.
2000[mAh] of battery capacity is used for calculation.
Note that the following value is not a guaranteed value, but only represents a calculated
value.
The values below were calculated with only the current consumption factored in. The cal-
culations do not factor in electrolyte leakage and other forms of battery deterioration.
Life time may be shortened depending on ambient condition.
1) 2 cycles/day
Annual consumption capacity =
(10h × a + 0.0014h × b + 2h × c) × 2 × 313 days + 24h × c × 52 days =
297.8[mAh] )
Battery life = 2000[mAh]/297.8[mAh] = 6.7 (6.7159) [year]
2) 1 cycle/day
(2nd cycle of the above 1) is for rest.
Annual consumption capacity =
(10h × a + 0.0014h × b + 14h × c) × 313 days + 24h × c × 52 days =
640.6[mAh] )
Battery life = 2000[mAh]/630.6[mAh] = 3.1 (3.1715) [year]
