How To Choose Dewalt 12V Battery Types
The 12-volt or 12v DC9071 battery powers most DeWalt tools, from cordless drills to jig saws. While all the types of 12v batteries DeWalt offers are rechargeable, there's a wide range of value, charge life and cost you need to understand when shopping for batteries. Find DeWalt batteries at your local hardware or construction supply store, or order them online. If you don't have a battery charger, you'll need one; you can find multi-type chargers that will charge any of DeWalt's 18v batteries.
Purchase 12v nickel cadmium (or NiCad) batteries if you are a casual drill user or if you need to purchase the least expensive battery type. While nickel cadmium batteries are rechargeable, Michael BlueJay's website, a well-known website reviewer, terms them "obsolete," you get very few recharges and they last 50 percent less than nickel-metal hydride batteries.
Buy nickel-metal hydride batteries if you use the drill semi-regularly and want a good value battery. These batteries go dead if you don't use them for some time, so they make poor casual-use batteries. But they are easy to find, relatively inexpensive and offer a long life and recharge function.
Purchase lithium-ion batteries for the most value for your money. These are more expensive, but they have a long life, recharge well and don't lose a charge when not in use like the nickel-metal hydride Dewalt DE9071 drill batteries do. InfoBarrel notes that these can be recharged 2,000 times, making them a good battery value for the heavy drill user or the homeowner who plans to use the drill occasionally for many years.
How can I maximize the performance of my DEWALT drill battery?
There are several steps you can take to help you get maximum performance from your power tool battery:
Prevent the Memory Effect - Keep the power tool battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect.
Keep the DEWALT Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.
Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a tool battery has not been used for a long period of time, perform the new battery break in procedure described above.
Battery Storage - If you don't plan on using the cordless drill battery for Dewalt DE9074 a month or more, store it in a clean, dry, cool place away from heat and metal objects.
