Battery Calculation Worksheet
Use the procedure given below to determine the required standby battery capacity in Ampere
-
Hours (AH).
Note:
It is not totally accurate to
merely multiply the combined standby current (in amperes) by the standby time (in hours) to obtain the battery capacity (in ampere
-
hours),
since other factors (Go
-
Anywhere Hub charging capabilities, temperature, battery condition, etc.) affect battery operation. The following calcu-
lations will yield the theoretical minimum required capacity:

12V,4AH battery: No network connection, ~19.5
hours, with network connection ~19 hours.
•
12V,5AH battery: No network connection, ~24
hours, with network connection ~23 hours.
With 4AH battery, a system without Wi

transceiver without a network connection will last about
27.5 hours. With 5AH battery, the same system will last
about 34 hours.
Note:
Battery not supplied.
