Construction professionals depend on their tools to make a living, and those tools depend just as much on their batteries. Proper charging and storage techniques will make lithium ion batteries for cordless tools last longer. So get with the program and follow these lithium ion battery care tips to get the longest life and best performance out of them.

Proper Lithium-Ion Battery Care:

  • Li-ion batteries can handle only 800 to 1,000 charges. Don’t recharge a battery if you’ve used it for just a few minutes.
  • Don’t leave them in the car—either in the cabin or the trunk. Heat (above 140 degrees F) and subzero cold can reduce battery life by 15 percent.
  • Storing a battery in direct sunlight can really heat it up, so shield it from the sun.
  • Don’t store a discharged battery that has less than one-half charge. Give it a full charge and then store it.

Now that you know how to take care of your tool batteries, it’s time to check out these essential cordless tools for contractors.
