    Default Batteries in all of these autodarkening helmets

    As far as I know, all of the autodarkening helmets have batteries whether you can see them or not. In the more expensive brands, they are easily replaceable. In the less expensive brands (e.g. Harbor Freight) you have to open the glued plastic case to get to them. The batteries are not really charged by the sunlight or welding arc; the light just supplements the batteries so they last longer. In another solar powered device at home there is a super capacitor that stores electricity generated when the sun shines, even though there are also batteries in the device. I don't know if welding helmets have super capacitors. At any rate, since access to the batteries is not easy, it makes sense to wire in an external battery pack with two AAA batteries. Those batteries inside the helmet aren't anything special other than that they're small enough to fit inside the case. Battery holders are available from Radio Shack. This repair with external batteries worked on a Harbor Freight helmet for someone in my welding class.

    If you have the receipt from the store, they might be willing to replace it. Those helmets should last around 2-3 years of use until the batteries are run down and three months is awfully short. There could be another problem in the electronics that caused the batteries to run down, or they could have just been defective batteries. If the store won't replace it, you have nothing to lose by opening the case.

    I've been using this helmet for over 2 years, got it as a gift in 12/10. It gets used for a dozen hours a week at the minimum. Today I started getting flashed everytime. Had to use my backup 12 shade helmet.

    Gonna try to cut it open and replace the batteries. It's been a really nice helmet.

    I didn't have to cut it open, it came apart with a thin blade screw driver. The batteries in my helmet was a CR2430, I have the replacements on the way. They appear to be soldered to the battery and the circuit board.

    Default Update on Kobalt welding hood.

As I understood it, in articles about the hood, it has no batteries. It receives its power from the solar cells. My fellow welder at the shop owns a Hobart and has to replace AAA batteries occaisionally. I can find no place on my hood that would hold any access to batteries. The welding lens won't even come apart without breaking it. I have used it for 4 years and have not had to change a battery yet
    After over 6 years of using this hood just about every day all day long, it has finally gone out on me. I have found that it does contain 2 lithium ion batteries that can be replaced, although you have to cut the case open and the battery terminals are spot welded to the batteries, they can be replaced with new ones and the casing glued back together. This hood and I have done a lot of welding together and I would like to keep it as long as I can. The headgear is not available for replacement, so I modified my hood to use Hobart headgear which is easily available from the local Tractor Supply store. I like the feature this hood has of always being ready to go without having to turn it on. My partners Hobart hood sometimes gives him a bit of flash blindness when he forgets to turn his on after it has timed out and reset itself. I can leave mine on my welding table for an hour and go right back to it without having to turn it back on.
