Where do i buy a battery and a charger for a fatmax rl250 laser level

You will have to buy charger for Stanley fatmax 700 it will cost you around 12$ to15$. You can buy it from any online shopping website like eBay or any other.

You can't fix this, you will need to replace the tool.

The laser assembly is almost 300. There are brushes under the head that could be worn out.

I know one thing about green lasers. They go on and on and they are visible for miles if you could see that far. I only know what a green gun laser can do. Only draw back is they are traceable. So if you want to have something you can see well, go green. Buy so rechargeable batteries to save money and you'll be fine not sure if that helps any, but I just now the power of green

I know it's 3 years old this question but I had the same problem. Good thing is the makita battery willl fit. I just got one from ebay works great

Try Gasweld or any Stanley dealer.

find the adjuster on the bottom. if a self adjuster, return it where you got it.

Use a second measuring tool and compare the results, or you can measure a known size or length (floor tiles for example)and check the reading you get.
