Wow, totally awesome deal even if it's the small battery. Perfect for simple m18 drill applications.

Agreed I have been using the bigger batteries for my Milwaukee Brad nailer and it gets tiring quick

I like this battery size and use them in my impacts and Jig Saw and nailers. They last for a long time in most low draw tools. I didn't buy from this seller. The only flashing light problem I have ever had was me not inserting the battery far enough into the charger. I don't know about other's issues.
