| bought an auto darken about 6 years ago, absolturely love it. don't have the brand handy.
Had a solar panel to charge the built in battery. eventually the battery failed, at about the 3 year mark, weld shop said 90% of that model did. Storing in a cupboard made it worse. Storeing in direct sunlight, or close to a lamp for a about 3 days helpd it for a while but eventually died.
so he recommended one with the solar trigger panel, but with replaceable separate battery | |
