Yes, He did it actually But Western always tried to hide it. So called Inventor Votla used same method as Maharishi Agastya written in Agastya Samhita. Agastya Samhita describes the method of making electric battery.
Agastya Samhita Says:
संस्थाप्य मृण्मये पात्रे ताम्रपत्रं सुसंस्कृतम्।
छादयेच्छिखिग्रीवेन चार्दाभि: काष्ठापांसुभि:॥

Water will be split by this current into Pranavayu and Udanavayu. A chain of one hundred jars is said to give a very effective force. When a cell was prepared according to Agastya Samhita n measured, it gives open circuit voltage as 1.138 volts and short circuit current as 23 mA.
