Brushless motors have taken over the cordless tool industry—and for good reason. They deliver more power, longer runtime, and significantly less wear than brushed alternatives. But even the best brushless motor won’t last forever without proper care. The Ryobi One+ HP 18V Brushless Reciprocating Saw PSBRSS01B is a perfect example of this new wave: it’s compact, powerful, and built for demolition work. Yet its longevity depends entirely on how you treat its battery, electronics, and motor.
If you own any brushless cordless power tool—whether it’s a drill, saw, or multitool—you need to understand the three pillars of care. This guide covers battery health, electronic moisture protection, and motor lubrication. We’ll also highlight some of the best brushless tools on the market today, including the DEWALT 20V MAX Cordless Drill Driver Set, Electric Drill, Brushless 1/2 In 2 Speed, the Dremel 8150 8V Cordless Rotary Tool Kit with Brushless Motor, and the Cordless Power 1450PSI Brushless pressure washer.
Why Brushless Motor Dominance Requires Smarter Maintenance
Brushed motors use physical carbon brushes that wear down over time. Brushless motors eliminate those brushes, relying on electronic controllers to switch the magnetic field. That means fewer moving parts and higher efficiency—but it also makes the electronics more sensitive to heat, dust, and moisture.
According to real user feedback on tools like the Ryobi PSBRSS01B, early failure often comes from the battery management system (BMS) or the motor controller, not the motor windings themselves. That’s why battery and electronic care are just as critical as motor maintenance.
Battery Care: The Heart of Brushless Performance
Your brushless tool is only as good as its battery. A weak or mismatched battery forces the motor controller to work harder, generating excess heat and reducing efficiency. Here’s how to extend battery life in any 18V or 20V system:
- Avoid complete discharges. Lithium-ion cells degrade fastest when drained below 20%. Recharge when you notice a drop in power.
- Store at moderate temperatures. Never leave batteries in a hot car or freezing garage. Ideal storage is between 50°F and 80°F.
- Use the correct charger. Fast chargers are convenient but generate heat. If the tool is warm after use, let it cool before charging.
- Rotate batteries. If you have multiple packs, rotate them evenly to avoid overusing one.
Many high-end brushless tools now come with two battery kits. For example, the DEWALT 20V MAX Cordless Drill and Impact Driver, Power Drill Brushless 2-Tool Power Tool Combo Kit includes two 2.0Ah batteries and a charger. That setup lets you work continuously while one pack cools.
Electronics Care: Protecting the Motor Controller
The brushless motor’s “brain” is the electronic speed controller (ESC). It’s a circuit board that regulates power to the windings. Dust, moisture, and vibration are its enemies.
- Keep air vents clean. Most brushless tools have intake and exhaust vents. Blow them out with compressed air after every heavy-use session.
- Avoid submerging. Even IP-rated tools like the Ryobi PSBRSS01B are not designed for water immersion. Wipe down with a damp cloth, never hose off.
- Inspect for corrosion. If you work in humid conditions, open the battery terminal area and look for green or white deposits. A light application of dielectric grease on the contacts helps prevent oxidation.
For tools that see harsh jobsites—like a rotary hammer or oscillating saw—consider using a dust shroud.

Motor Care: Lubrication and Cleaning
Brushless motors still have bearings and rotor assemblies that need attention. Unlike brushed motors, you don’t have to replace brushes, but you do need to keep the motor free of debris.
- Use compressed air regularly. Remove the battery and blow out dust from the motor housing. Pay special attention to the rear bearing area.
- Lubricate sealed bearings sparingly. If the motor develops a squeal (not from the gear case), apply one drop of synthetic oil to the bearing access point. Most DIYers never need to do this.
- Watch for overheating. If the tool feels hot past comfortable touch, let it cool before resuming. Overheating demagnetizes the rotor magnets, leading to permanent power loss.
Tools like the Dremel 8250-5 12V Lithium-Ion Variable Speed Cordless Rotary Tool with Brushless Motor have built-in thermal protection, but even that won’t save you from repeated abuse.

Maintenance Checklist for Everyday Use
A simple routine can double the lifespan of your brushless tools. Follow these steps after each project:
- Remove the battery and wipe down the tool exterior.
- Blow out dust from vents, blade clamp, and trigger area.
- Inspect the blade or bit for damage. Replace if needed.
- Check the battery contacts for dirt or corrosion.
- Store the tool in a dry, room-temperature location.

Frequently Asked Questions
Why does my brushless tool lose power after a few minutes?
This is often a battery issue. The battery’s BMS may be cutting power due to heat or low voltage. Let the battery cool and check for a fully charged pack. If the problem persists, the motor controller may be failing.
Can I use a non-OEM battery in a brushless tool?
It’s not recommended. Third-party batteries often lack proper BMS communication, which can cause erratic behavior or damage the controller. Stick with the manufacturer’s batteries for best performance.
How often should I lubricate the motor bearings?
Most brushless motors use sealed bearings that never need lubrication. If you hear a grinding noise, it’s usually a sign of contamination, not lack of oil. In that case, replace the bearing or the motor assembly.
Is it safe to leave my battery on the charger overnight?
Modern chargers are smart and switch to trickle mode, but it’s still best to unplug once the light turns green. Continuous connection can shorten overall battery life.
