Milwaukee V18 Lithium-Ion Battery and Charger Multipack — Two Batteries, Model# 48-11-1833  Product Reviews

"The lithium batteries are the next generation, can be charged anytime without getting a memory set. As TONY THE TIGER would say, "There GREAT"."

"The 18-volt Lith-Ion do deliver longer lasting power than the Ni-Cads and the built-in charge indicator is a useful innovation."

"I can't wait until all my Ni=cads die so I can buy all new lithium batteries, They last twice as long and they are half the weight. Don't forget the charging gage, they work as good with a quarter tank = a full tank at full power."

"I had bought the new lithium-ion 18v 1/2 inch hammer drill and loved it. When I bought the drill got a bonus free matching sawzall but just the two batteries weren't enough. Started looking for more batteries and found this deal. Got two more batteries and an extra charger for about half of what all this would have cost purchased separately. These batteries are great they have much longer run times, deliver constant output. Be aware it takes some getting used to, these batteries don't slow down like regular batteries. They run full power till the little smart brain inside says the battery is run down as low as safe and they just shut off. Now I've never had one stop while using but you can drill a hole and everything is fine then when you go to drill another hole the drill is just dead, the little brain at work. Luckily the battery has a built in charge indicator, you just press the test button and a series of led's light up and let you know how much charge remains. Once you get used to testing the charge before you start using you won't have a problem and the longer run times are excellent. Also these batteries don't get hot when using or charging so you don't have to wait to let them cool and can get more use out of them in a day without fear of ruining"
