I got these from an Amazon seller by mistake -- I ordered something entirely different, and the seller eventually decided that I can keep these without returning them.

They are brand new, but I don't know what power tools they fit, and the manuals don't tell me. Please check the photos carefully (or maybe search for the model numbers, below), and if they look like they'll fit your tools, you're welcome to have them.

There are two batteries, and I'm pretty sure they fit the charger, although it looks like the charger can also take at least one other kind of battery.

Model number of the batteries is MWL1810, model number of the charger is MWC903.
