I am after a replacement battery for my Topcon surveying equipment; however, the one I have says it is 4V. I need it with my FC200 field controller and GRS-1 handheld GPS receiver. It appears the one you sell is compatible, but the voltage difference is a concern.

Our references don`t include GRS-1 so i would not risk it sorry. Can`t explain the voltage difference to be honest. Thats a bit strange. The one you have is obviously single cell whereas ours is 2 cell.
