Battery type The type of batteries provided with the drill. All are rechargeable. The more common type is denoted NiCd, for its nickel-cadmium components. Nickel-metal hydride (NiMH) batteries boast added energy for their weight. Lithium-ion (Li-Ion) batteries are the latest type and deliver even more power in a smaller size. Lithium-ion and NiMH batteries can be disposed of with regular refuse; NiCd must be recycled.

Battery recharge time (in minutes) The time it takes to completely recharge a battery after it has properly cooled down. Most of the fast chargers have a built-in temperature sensor that delays the charging cycle when the battery is too hot from recent heavy use until the battery has cooled.

Speed ranges Many cordless drills have two separate speed ranges, or gear ratios; some newer models have three. The slower speed range peaks at about 400 revolutions per minute (rpm) and provides increased torque (twisting force) for driving large screws. A higher speed range that reaches about 1,500 rpm or more, is well suited for rapid drilling. Lower-priced drills usually have a single speed range that tops out at approximately 600 to 800 rpm, compromising both driving and drilling performance.
I have 8 of these and do some light seasonal installation work on 4-6 projects a year. These were a great value 5 years ago, but the batteries on my newest drills have now died after less than a year of casual use. My 6 year old batteries, while fading fast, will still hold a charge while stored for 1-2 weeks. My new batteries store a charge for 12-24 hours a best, then they are 99% dead and need to be re-charged. This is [@]'s house brand and I think the newer batteries low performance is a subtle way for them to encourage customers to move up to the Lithium ion battery units. I would like to see many of the new Lithium units(their are several new models out their which have not been reviewed as of 2/2012)reviewed ASAP because the old Ryobi batteries are now worthless. Save your money and go to the much lighter and better Lithium models.

Comment:
I have 5 drill motors,7 batteries(recycled 3) 5 chargers. When I need a new battery its a better deal to get aKIT of some natureThis leaves me with 2 circular saws,three lights,2 radios,one orbital sander. These work OK but usually I use a corded sander, circular saw.I'm at the point of switching to Lithium ion but once again a battery alone is not a bargain.I have had this assortment from 4 to 1 yrs.. At least half of the tools have never been used.The best thing about the drills is I can drill/ counter drill/ counter sink/ drive the screw all without changing bits/ drivers.

Great all around drill. Switch to the lithium batteries. They are lighter and last longer.
