Great for high demand use
The 9.0 battery is great when you need lots of power for long times such as a reciprocating saw or impact or circular saw. It is extremely heavy for normal use such as with a drill or hex impact. The fast charger is great especially for the 9.0 battery. It charged my new 9.0 battery faster than the regular charger could charge my 5.0 battery.

Love this battery. 9.0 def feel the power compared to the 5.0 in the miter saw. Also used it in my 7 1/4 cordless circular saw and cut it like a corded tool. Def like this battery and platform.
