This video is made for the learning about lead acid battery cell, and how it is built . But not for using as commercial purpose . so please let us consider this video as to learning the process of a Battery and it's system of work. I gifted this video to you because you can make any batteries manually at your home , without any welded machine. Again, when a battery plate is found damaged , you can change it. I first put 7 plates again in 5 plates, finally I finished the battery with 3 plates. Hopefully I will be able to help you with all your problems. thank you.
