I don't remember what it is called , but it measure the acid level and if the battery is good. So I bought a battery tester and here is what I found. Now I have 2 batteries in my MH, The first battery all 4 balls floated to the top indicating it is fully charged. The second battery , the first cell all 4 balls floated to the top, second cell only 1 floated and the last cell all 4 balls floated. Now does show I need to replace the battery, if it does that means I will replace both. I called the local battery shop and they said I needed to replace it.I asked if I could add acid to the cell to bring it up to the correct reading, the response was no, I need new batteries. any comments would be helpful, thanks
