Answer / karthik raman.b

its depend on current of the load which connected to the battery amphere per hour if a battery having 10AH it can give 10A load upto a hour

Answer / krish

it depond upon the output load

Answer / avinash

First you must know the ampere-hour of your battery bank as
per the manufacture's specification.Now discharge the
batteries as per the C5 rating( for Ni-Cd batteries) or C10
rating (for Lead -acid Batteries).Discharging can be done
by connecting the positive and negative terminals of
batteries to the copper plates and immersing in a salt
solution, which will act as a load. The distance between
the plates can be adjusted to set the discharge current.
Measure the amount of discharge current and time till the
battery voltage of each battery in a bank drops to 1 Volt
if it is a 1.4 volt cell. Now multiply the discharge
current and time. This is the measure of the Amperehour
capacity of the bank.If the Amppere -hour capacity as per
the manufacture is available then you can determine the
percentage capacity of your bank at present.Remember that
charging and discharging of battery bank improves the
health of the battery bank.However, for lead -acid
batteries these cycles are around 750 or say 3 years. For
Ni-Cd batteries the life is around 25years or more if
maintained properly.Selecting a overated battery is also
not adviseable as it won't get discharged completely and
this may result in sulfation of batteries and early death
of battery bank.

Answer / mahesh meshram

Calculate the AH of battery as said above or the given by the manufacturer if is same then ok if not then take actual calculated. If capacity of battery is 10AH and load current is of 10A then it will give back up for 1H

I have carried out wiring for lighting in a shed in Industrial area which contains Metal halide lamps & have balanced in 3ph.Now when we put all the lines on in the daytime the current taken at 3phases at MCB comes to be equal i.e.28,29,28Amps respectively but in the night time i.e between 7p.m.to 11p.m. at the same MCb the current is 52,59,62Amp, though I have fit 63A MCB it is tripping in the above period.What may be the reason.? Note: This industry is located in industrial area where majority of steel ingot manufacturing plants are there. Whether this may be due to harmonic? what should I do to overcome above problem.pl suggest urgently.
