Doesn't work with rechargeable batteries. If you push the batteries down the right way, it'll turn on for a second or two. And then it won't turn on again after it turns off. You'd have to hope the thief, pushes down on the batteries just right. I took the batteries out and in multiple times, it doesn't want to turn on. The head of the screws, is plastic or something, you'll damage it unscrewing it. I could send it back, but they might not want it back. Buy a different light instead. To lazy to put it in a box and ship it. Also, not 100% free to ship it back, costs toner, drum, and label paper. Might work if you use regular batteries. There doesn't appear to be an alternative C battery powered motion activated light. Not that many on Amazon. MAXSA Motion-Activated Anywhere LED Light, Battery Powered Weatherproof Light for Indoor & Outdoor Use, Black 40230 Costs more, but uses four batteries, instead of three. The white one is $15. Update 1.4 volts per battery isn't enough? Says it needs 1.5 volts per battery. Probably thinks it's a dead battery not being 1.5 volts. And the batteries I bought are only 1.2 volts. If that's the problem, you need NiZn batteries. Don't know if my charger does those. I'll just buy the MAXSA light. The stupid light damaged part of the battery, the condom that protects it from the vagina. It's peeling off on the top, where it needs it most. Doesn't say how many volts it requires, I'll assume it'll work then.
