Canāt exactly say how much as once I prepare then I prepare least 30 liters as I got two phoenix batteries? left behind electrolyte goes into empty bottles for to be used later, least not wasted.
Since, lot of heat is produced so good quantity of water evaporates. Later, I have to readjust the gravity as electrolyte takes around 24 hours to cool down so I kind of leave it alone for this period.
Later, once you make a fine adjustment using de-ionized water then you donāt experience any heat or chemical reaction so its kind of easy then.
Who activity is preplanned a week before, where first I buy sulfuric acid then buy de-ionized water, make sure all things are ready such as gloves, rough clothes and specific plastic container, equipmentās used and a secure place.
My domestic servant is kind of very well trained now as I kind of only supervise him. I just watch the show as I have taught him as how to handle things.
