Well first contact Milwaukee, and notify them of the problem you having, see what they say. Its most likely the battery's might have some bad cell's, if you have an multi meter you can test each battery to see what voltage you are receiving. And after that you can open the case and check each cell ( let me remind you contact Milwaukee first before attempting this because if you open there devices, you voided the warranty) and replace what ever cell that is bad, you can find the battery cell's online

does anyone know of one that comes with battery and charger included?

Big orange sent us the 100 lumen older version light. Don't buy unless you can see it in person to verify it's the new model or it's substantially marked down. The new version of the M18 is a great add on if you already have an M18 charger and batteries. Power outages happen around here and we can keep this running for days with the M18 batteries and promised 24 hour plus run time with a 5.0 AH M18 battery. The new version puts out nice clean light, you can set it on a flattish surface or hang it, and you can adjust the direction of the light. It's a basic on or of no zoom, no hi and low setting, just a simple light that works. Nothing special about just a light that works with the M18 system. There are much better options like mag lights or head lamps that take replaceable batteries if you don't already have a charger and battery.

A must have for the Milwaukee weed trimmer (2725-21HD). One battery isn't enough for larger properties, so having a second battery on hand is great. Took me about an hour to fully charge using rapid charger, and lasts about 30-40 minutes with my weed trimmer on high speed mode. The only drawback is the price for one of these high demand batteries.
