The EDTA is a dry powder. It will dissolve easily in water but not in battery acid. When EDTA has been dissolved in water, the solution will then mix easily with battery acid. EDTA is considered non-toxic (but, we advise against ingesting it!)
The amount to use depends on the size of the battery and on how much sulfate it has. In general, use one tablespoon per cell in a golf cart battery such as a Trojan T-105. There are approx. 40 tablespoons in one pound. EDTA has a near infinite shelf life.
In general, the instructions are to use one tablespoon of EDTA per quart of electrolyte of the cell or battery to be treated. If you do not know the capacity of your cells, then use one tablespoon per cell for deep cycle batteries such as golf cart batteries and two tablespoons per cell for larger batteries.
Mix the required amount of EDTA with just enough water to completely dissolve it. Add this mixture to the battery cells so that the cells get the amount indicated above. You can mix a batch big enough for all the cells and then divide it up; or you can mix a batch for each cell one at a time. You may have to remove some acid with your hydrometer to make room for the water and then put the acid back later when the liquid level has gone down. Some people mix EDTA into the make up water as a preventive measure. As always, use of this product is at your own risk!
