    I think the 6v battery is dead, 6v made by Eagle Picher, Carefree. The
    voltage measure 0.5. Do these rechargeable batteries get this low under
    ordinary circumstances?

    Really deep discharge, it's possible. I believe these are NiCad?

    Try charging under bright sunlight for a day. Read the battery
    voltage while it's charging, and see if it goes up. If not, there may
    be a loose wire or bad connection somewhere. That seems to be a
    problem with these outdoor lights.

    You could always just try a new battery and see if it works.

    Remember to recycle the battery when you buy a new one. If you buy
    where you bought the lamp, Brinkmann guarantees they'll take it back
    for recycling.

    Good luck

    Thanks. I'll try your suggestions. We have plenty of bright sunlight here in
    N. Calif. today.

    I suppose it could be the solar cell. How would one go about testing it?

    Put your DMM leads on the battery, and place the solar light in
    sunlight. Since the battery isn't dead shorted, you should see a big
    increase in voltage in sunlight.

    Good luck

    Too obvious! Thanks. :) The cells are producing 9v.

    OK, Mr. Watson. I'd guess the charging part is working. Wait a bit
    (at least a couple of hours), and with the DMM still connected, cover
    the solar panel, then check the voltage. Unless it's quite a bit
    higher than 0.5V, the battery's probably cashed.

    Eagle Picher Carefree IIRC is a Sealed Lead Acid chemistry, it's a
    square brick similar to those used in emergency lighting systems. If
    it's gotten down to that low of a voltage it most likely won't come
    back. That has been my experience in the past with very deeply
    discharged SLA batteries. They might exhibit the correct terminal
    voltage when under charge but the minute a load is applied they crap
