The difference between 150Ah and 160Ah batteries?
150Ah vs 160Ah?
Let's first understand what is Ah (ampere-hour) in batteries.
'A' stands for ‘Ampere’ is the unit of electric current whereas ‘he signifies 'hour' used as the unit of time.
If the battery of value 'XAh' can deliver X ampere current continuously for one hour.
For example, If the requirement to run a motor is 10 Ampere for a load to work. Then the 150 Ah battery can deliver the same current for 15 hours whereas the 160 Ah battery is capable of delivering the same current for 16 hours.
However, this will answer your questions but this knowledge is not sufficient hence I would like to add few more points.
Let me illustrate this with an example using home appliances usage.
Suppose at home you want your 3 Fans, 3 Tube lights, 3 9watt LED bulbs & 1 television to operate at the time of power failure using your battery system.
The power consumed by these items as follows:
Power consumed by 3 Fan (70 watts for each fan) = 3x70= 210 watts
3 Tube light (60 watts each) = 3x60watt = 180 watts
3 9watt LED bulbs = 3x9watt = 27 watt
1 Television = 120 watts
Therefore the total power requirement is 537 watts.
The Questions may arise in one's mind as:
1)How much backup time will my inverter provide If a 150Ah battery is used?
2)How much backup time will my inverter provide if a 160Ah battery is used?
3)Which one of both batteries should I choose as per my home requirement?
To explain these questions simply. Let's consider any two Inverter batteries available in the market.
For example
Battery 1:(150Ah)
Luminous Life Max 18075
Specifications:
Ah rating: 150Ah
Technology: Tall Tubular
Nominal Voltage: 12 Volt
Let's calculate the ideal backup time of the battery.
For the above battery, the battery voltage is 12V and the Ah rating is 150Ah. Since our home requirement as per our example is 537 watts. So the total load is 537 watts.
Substituting the corresponding values in the below formula.
Back up time = ( 12vx150Ah)/537watt = 3.35 hours (approx).
Battery 2:(160Ah)
Luminous ILTT 20048
Specifications:
Ah rating: 160Ah
Technology: Tall Tubular
Nominal Voltage: 12 Volt
Now, Let's calculate Back up time for the Inverter powered with 160Ah Battery.
Back up time =( 12x160)/537 = 3.57 hours (approx)
Both batteries are good but it can be concluded that a battery of 160Ah will have more backup time compared to a 150Ah battery provided their battery voltages are the same.
However, the real-time backup will be less than these calculated Ideal values as no Inverter can operate at 100 percent efficiency. There will be losses that reduce the efficiency to 60 to 80 percent as a result back up time also reduces to 60 to 80 percent of Ideal back up time.
About Battery Capacity
What means Battery C10 and C20 and their difference?
We will know what it means to write C10 and C20 on the battery.
Friends, first of all, know that the battery doesn't need to be of C10 and C20, the battery can be of any rating. Like - C5, C10, C20, C25, and many more.
Battery capacity explained
Apart from this, you should remember the other thing that the value of C written on the battery is not only for the solar battery, it is on all types of batteries. C indicates the capacity of the battery. If you do not get a C rating written on any battery, then that battery will be either C20. And if you want to find the right one, you can read the manual of that battery, you will know from there how much the C value of that battery is.
C10 means C20 - C in this means the capacity of the battery, and the count written with C indicates the hour.
Battery capacity explained
All our electrical equipment has a capacity, how much current can we pass through it. For example, you can understand the motor.
Like- its capacity is 10 Ampere written on a motor, now if I remove more than the 10-Ampere current from that motor, then it will be damaged.
Similarly, how many amperes we can pass inside our battery is shown by the value of C written on the battery.
Battery C10 meaning
If a C10 is written on a 150 AH battery. So this means that I can neither charge nor discharge that battery in less than 10 hours.
Example- We have a 150AH C10 battery. So we cannot charge this battery more than 15-Ampere current, nor can we run more than the 15-Ampere load on this battery at one time.
How to know - how many amperes we will charge and discharge the battery?
Battery Charging & Discharging Capacity
For this, first, you have to see the Ah of your battery, how much Ah battery it is. And after that, you have to find out its C value.
For example, to find the charging and discharging capacities of a 150AH @ C20 battery.
150-Ah-C20-battery
For this, we have to put a part of C (capacity) inside our battery's Ah. So now we will put 20 within 150. (150/20 = 7.5) This means that I can neither charge the 150AH @ C20 battery at more than 7.5 ampere, nor can I run more than one device at a time.
Last answer- The C10, C20 value written on the battery indicates the charging and discharging capacity of that battery. That we can add as many amperes as possible.
So guys, hope that many questions related to the C10 C20 written on your battery will be found today.
