Using time of battery depends on the capacity of battery and the power of loading. Formula as follows:
t=(A.V. η)/P
Of which:
- t: is a time to use battery(Hour)
- A: Capacity of battery(Ah)
- V: Voltage of battery(Volt)
- P: Power of load(W)
- η: The using coefficient number. It is usually approximatly 0.7
For example, you have a battery 12V, capacity 100Ah and sub load power 100W, the using time will be T (hours) = (12x 100x 0.7)/100(w) = 8.4 (hours)

Notes:
● The formula is is better for the ensure quality battery.
● The maximum let out curent of battery’s not more than 3 times the amount of battery operating time in this mode is not more than 3 minutes continuously. It is usually choosed to battery capacity to work 2 hours or more.
● Please contact our Technical Department for more detailed instructions and precise.
● The factor of used battery: η changes in level of battery let out.
+ η ≈ 0.8, 0.9 if let out current < 20% capacity of battery.
+ η ≈ 0.7 if let out current <= 70 % capacity of battery.
+ η ≈ 0.6, 0.5 if let out current >70 % capacity of battery.
