    I have a nicad wet cell batery of 24 cells which has been stored empty with the output shunted for years. These are valuable and I don,t want discard.

    I know that the electrolyte is aprox 70% water and the rest potasium hydroxide.
    But I also know that is a percentage of lithium hydroxide to help preserve the posi
    tive plates. This latter is my problem. I know that specefic brands have their own formulas, and are hesitent to comment with out knowining what I have.

    I am onlly looking for an aproximation. I am now thinking of between % and 8 percent lithium hydroxide. If I damagen these cells , I am no wores off.

    I have the reageant grade chems and am aware of mixing and safe handleing.

    Would love any help.

    Wet cell niceds are sometimes called "flooded" to difer them from "dry" cells. Sorry about the confusion.
