In analogy to the proposed gravitational "fifth" force, limits can be set on the range $\ensuremath{\lambda}$ and the strength $\ensuremath{\beta}$ of an electrical fifth force. Specifically we consider the potential $V=\frac{({e}^{2}}{r)}(1+{\ensuremath{\beta}e}^{\ensuremath{-}r\ensuremath{\lambda}})$ and show that there is a region near $\ensuremath{\lambda}=1$ \ensuremath{\mu}m where existing experiments set relatively poor limits on $\ensuremath{\beta}$.
