Today, bluevelvetrestaurant.com would like to introduce to you Amp Hours??? Battery Capacity Explained. Following along are instructions in the video below:
” s up youtube. This is lds reliance. We use batteries in our everyday life. All all the time.
But not very many of us. Know really how they work or much about their characteristics and though one of the biggest questions that i get asked is about capacity capacity means the actual quantity of electricity that you can extract out of a battery from one cycle of fully charged battery to fully discharged battery. So how do we measure. Capacity.
Well you may have noticed on some batteries like. This power..
Tool battery. A measurement. That says. 40 aah or 40.
Amp. Hours and an amp power is the amount of energy charged. In a battery. That will give you 1 amp.
Or 1 ampere for one hour. So that s pretty simple..
But unfortunately it gets more complicated. Most battery manufacturers do not all use the same measurement for calculating amp hours. Or capacity. Some of them will use a 10 hour rate meaning.
It takes 10 hours to discharge the battery. Other people will use 20 and others will use 100 so you need to make sure that you look at the fine print on the label. So here s an example of a battery that uses the 100 hour rate. If you were to compare this to a 20 hour battery.
You would think that this was much better. However you need to convert the the run rates to the same measurement to be able to compare them accurately..
So what does this all mean well. We let s take a 225 amp. Hour battery. Which is measured.
At the 20 hour run rate. And do a simple math problem. So you cross out the hours on the top and the. Bottom and you divide the top by the.
Bottom and you get 1125. Amps and what that means is that this battery is rated to produce 1125 amps for 20 hours straight..
So the last thing that i wanted to mention in this video. That s very important is that the more current you draw the more you lower the capacity of the battery so in this chart as you ll see on the right side the. Further most extreme is 033. Amps.
This battery will we ll run that for 20. Hours but if you were to draw 30 25. Amps it last four minutes so keep that in mind when you re when you re talking about how much battery capacity. You need for a specific application thanks for watching.
