Answer / aayush

But dear Sunil, how will I calculate that? If I have a 12V
Battery and I dont know its AH, then what is the method to
find that?

Answer / sunil kumar

AH Ampear Hour= ampear X hour, defined as constant ampear
delevered in hour. 180 AH meanes 180 A current will be
delivered in one hour.

Answer / sree

Formula is
n-1/2*15
n = no of Plates ( Plates details indicated in the Battery )

Example
We have 27R 12V Lead Acid Battery
27-1=26 26/2=13 13*15=195AH
Answer is 195AH

Answer / z_hosen

Every Battery must provided AH. and AH is ampear X hour.if
10AH rating of the battery then it means 10 A current will be
delivered in one hour or 1 amp current will be delivered in
10hours and so on....

Answer / sree

Formula is
p-1/2*15
p = no of Plates ( Plates details indicated in the Battery )

27-1=26 26/2=13 13*15=195AH
Answer is 195AH

Answer / ravikumar josyula

AH capacity of the battery is the current required to
discharge the battery from its full charge voltage to full
discharge voltage and the time taken to do so.FCV of a cell
is : 2.2 or 2.3 volts , FDV is :1.9v.
If we know the no plates of a battery then can calculate
the capacity as above. Otherwise full charge it and the
discharge it to full discharge voltage.mutiply the time
taken to get fully discharged in hours and the current
drawn in amps.

Answer / sure

Can calculate based on positive plate dimensions.

Answer / vinay kumar

we can calculate AH how many the cells in the battery
