What is the best way to restore a lead acid battery?

What is the best way to restore a lead acid battery?  The battery is a small 4V battery out of a flashlight.

    I would suggest replacing it with a LiPo battery unless it's a 'vintage' flashlight that has to look original. I am doing a similar exercise with a vintage lead acid glass accumulator using a LiPo single cell and a 'buck/boost' converter. Many modern LED flashlights seem to use the same method?
    Just a thought...maybe a photograph of the battery may help other contributors....
