RIDGID18V Lithium-Ion 2.0 Ah Battery and Charger Starter Kit

what is the input voltage of the charger? 110v or 220v?

will home depot still offer the lifetime if i buy from you? what the ad says and what they will really do is the question.

So the newer ac8400802p and the r840086 2ah battery should work on the r86008 drill driver? and secondly what's the difference between the ac8400802p

Will this work with the ridgid 18-volt cordless hand vacuum with crevice nozzle, utility nozzle and extension tube model #r860902b ?
