Power Tool Battery Replacement Cost vs New Tool

When buying new equipment, you’re not just getting a motor and gearbox—you’re securing warranty coverage, REDLINK intelligence protection, and access to the full ecosystem of accessories that make work easier over years of use.

Milwaukee 2904-22 M18 FUEL Hammer Drill Kit ($199–$249)
The kit includes one M18 battery and charger. The tool itself weighs 4.3 lbs with REDLINK Plus intelligence preventing overheating during extended drilling operations. Five-year warranty covers both tool and battery.

DeWalt DCD999B 20V MAX FLEXVOLT Hammer Drill ($169–$199)
FLEXVOLT batteries run at 60 volts for high-torque applications, then drop to 20V for lighter work. The 4.9 lb weight feels heavier than M18 competitors but the metal ratcheting chuck holds up better over time.

Makita XPH14Z 18V LXT Hammer Drill ($119–$139)
Lighter at 4.4 lbs with brushless motor delivering smooth operation and minimal vibration. Lower max torque than FUEL or FLEXVOLT options but perfect for finish work and interior framing.
