Power Tool Battery Life Tips

Best Practices For Cordless Power Tool Battery Life

We take great care of our power tools, ensuring they are stored safely, kept clean and in good working condition. An important component of cordless power tools is the Battery Pack.

To help to ensure the maximum life out of your battery pack, we have a checklist of best practices to follow to help get the best out of the Battery Pack.

 

For the battery to take a full charge, it is best to charge it up at room temperature. This will help ensure that the batteries perform best.  In extremes, such as above 105 degrees Fahrenheit or in cold temperatures as an example below 40 degrees Fahrenheit, the battery pack won’t take a full charge and could potentially suffer permanent damage.

Place the battery pack in the charger immediately after finishing using the power tool, provided the Battery Pack isn’t hot to the touch.  If the battery is hot, then leave it out of the charger. Ideally for at least 2 hours to enable the battery to cool. Then once at room temperature,  replace it into the battery charger.

 

Battery Storage

Battery Packs and power tools must always be stored in cool, dry storage places. Storage in extreme heat (120 degrees or greater) battery life may be reduced. NiCad, NiMH and Li-ion batteries will self-discharge during storage.

For power tools that use 3-Stage Charging System, it is advisable to charge the battery overnight from time to time. This should help preserve battery life and ensure optimum runtime.

Breaking In New Batteries

All brand new cordless drill batteries come in a discharged condition and so need to be fully charged before you can use them.  It is recommended that you fully charge & then discharge your new battery ideally twice (or up to four times if you have enough time to do so ) to allow it to reach its maximum rated capacity.

New cordless drill DeWalt batteries should be left on the charger for at least 18 hours before using it for the first time.

 

Keep Your Batteries Clean

It’s a good idea to clean dirty battery contacts using a cotton swab and an alcohol based liquid cleaning product. This helps to maintain a good connection between the battery and your portable power tool. Meaning this helps power tool battery life, naturally.

Some batteries are built to enable lower self-discharge, which keeps battery cells active and ready for use. An example is the Makita BL1830 battery. This Makita BL1830B-2 18V LXT Lithium-Ion 3.0Ah Battery is a brand leader. As such we have used these for years on our Makita drills.
