If you're eyeing a new tool from Ridgid, Milwaukee, or DeWalt, now's a good time to buy — Home Depot's running a free battery promo across all three brands. Pick up a qualifying tool, and a battery gets tossed in at no extra cost, whether that's Ridgid's 18V 4.0 Ah pack, Milwaukee's M18 5.0 Ah pack, or DeWalt's Flexvolt 9.0Ah battery. Here's a deeper look at the tools that can get you free batteries:
DeWalt Flexvolt 20V/60V MAX Battery
The DeWalt Flexvolt battery pack automatically changes voltage depending on which tool it's plugged into. It powers DeWalt's 60V MAX Brushless line and 120V MAX Brushless tools, and it's also backward compatible with 20V MAX tools and chargers, so it's not locked into just one tool category.
Get it free with:

Milwaukee M18 5.0 Ah XC Battery
The Milwaukee M18 5.0 Ah XC Battery is compatible with any M18 cordless power tool in Milwaukee's lineup, and it's rated to deliver 2 x more runtime than a standard lithium battery. It also recharges fully in 90 minutes or less, so you're not stuck waiting around if you're mid-project and need to swap in a fresh charge.
Some of the M18 tools that qualify for the deal are:
- Milwaukee M18 Redlithium Forge Starter Kit with 8.0Ah Battery — - $279
