For US buyers seeking the longest written coverage, RIDGID’s Lifetime Service Agreement (LSA) is the clearest conditional lifetime option among the brands compared here. It can cover eligible cordless tools and qualifying batteries, but eligibility, purchase terms, registration within 90 days, approval, and original ownership all matter. For fixed-term coverage, Bosch lists five years for 18V tools and chargers, Milwaukee offers five years for many electric power tools, and FLEX extends eligible 24V tools, batteries, and chargers from three to five years with timely registration.
These terms apply to different product categories and are not interchangeable. Compare the specific model, battery coverage, enrollment rules, and claim process—not just the warranty headline.
How the leading cordless tool warranty programs compare
This US-focused comparison uses manufacturer warranty information accessed October 7, 2026. Terms can vary by model, kit, seller, purchase date, and region, so confirm the exact product’s current terms before buying.
| Brand or program | Published coverage in reviewed US-facing terms | Battery coverage | Key conditions |
|---|---|---|---|
| RIDGID Lifetime Service Agreement | Lifetime service for eligible products after approval | Qualifying batteries are included | Product and purchase must qualify; original owner must register within 90 days, provide proof of purchase and product details, and receive approval. Some eligibility is tied to The Home Depot. Replacement equipment may need registration within 90 days. |
| Bosch 18V | Five years for 18V cordless tools and chargers | Three years for 18V batteries | US warranty schedule. Normal wear and damage associated with non-genuine parts or unauthorized repairs are among the exclusions. Claims require returning the complete tool to a Bosch service center or authorized station. |
| Milwaukee | Five years for many electric power tools | Cordless battery packs are excluded from the general five-year power-tool warranty; separate battery terms apply | US and Canada terms, with product-specific exceptions. Proof of purchase helps verify coverage; registration is not required for the applicable power-tool warranty. |
| FLEX 24V | Three years standard; five years after qualifying registration within 30 days | The same three- or five-year schedule covers eligible 24V batteries and chargers | US and Canada. Proof of purchase is required for registration. Legacy 12V/18V and corded products have different terms. |
| Makita lithium-ion | Three years from original purchase for tools, batteries, and chargers, as stated in Makita USA’s FAQ | Generally three years under the FAQ | ConnectX portable backpack power supplies are identified as an exception, with a two-year term. Check the exact product’s warranty. |
| DEWALT | No general lifetime term for cordless power tools is established by the limited lifetime hand-tool warranty | Separate product-specific coverage | The limited lifetime warranty applies to specified hand tools that state they carry it. Electrical and electronic components are capped at one year under that wording. Check the cordless model’s own warranty. |
What RIDGID’s lifetime coverage actually means
RIDGID calls its program the Lifetime Service Agreement. It is a conditional service agreement, not an unconditional lifetime warranty on every RIDGID product. The reviewed terms describe free service and parts for eligible products, including qualifying cordless handheld power tools and batteries.

- Drill/Driver features a 3/8" chuck, 0-650 rpm ideal for consumer DIY projects, 11 position clutch to prevent stripping of screws and damaging work material and an LED work light for increased visibility in tight or dark spaces
- The circular saw's compact design makes it easy to use and reduces fatigue. The 5.5" blade is capable of cutting 2x lumber, and its high torque motor makes it ideal for consumer DIY projects. Adjustments are quick and easy with the tool-free depth of cut and bevel settings for angled cutting.
- Work light features up to 11 hours of runtime
- 2 batteries double the runtime for less down time on larger projects
- Part of the BLACK+DECKER 20V MAX* Lithium Ion Battery System
To preserve the potential coverage, the product and purchase must meet the program’s eligibility rules. The original owner must register within 90 days, provide the required proof and product information, and obtain approval. Check the exact kit and seller before purchase: the terms connect some eligibility to The Home Depot, and not every RIDGID kit should be assumed to qualify. If equipment is replaced, the replacement may need to be registered within 90 days as well.
Where the fixed-term options differ
Bosch: longer tool term than battery term
Bosch’s US warranty schedule lists five years for 18V cordless tools and chargers, but three years for 18V batteries. Its service process requires returning the complete tool to a Bosch service center or authorized station. That difference matters if battery coverage is a major part of the value you expect from a warranty.
Rank #2
- CMCD700: powerful motor: provides 280 uwo of power and 2 speed gearbox ranging from 0-350 RPM and 0-1,500 RPM for demanding tasks
- CMCF800: maximum torque: provides 1,460 in-lbs. Of torque 2,800 RPM and 3,100 bpm for heavy duty fastening
- CMCS300: speed: 1-in stroke length running at 3,000 SPM for speed of completing applications.
- CMCL020B: improved visibility: 140 lumens for improved visibility
Milwaukee: check the separate battery terms
Milwaukee’s US/Canada terms provide five years for many electric power tools, but cordless battery packs are excluded from that general power-tool term. Battery coverage follows separate terms, and product exceptions apply. Registration is not required for the applicable power-tool warranty, while proof of purchase can help verify the coverage period.
FLEX: registration unlocks two additional years
For eligible FLEX 24V tools, batteries, and chargers, the published schedule is three years by default and five years after qualifying registration within 30 days. Proof of purchase is required for registration. Do not apply this schedule automatically to FLEX legacy 12V/18V or corded products, which have different terms.

Makita: three years, with a stated exception
Makita USA’s FAQ states a three-year term from original purchase for lithium-ion tools, batteries, and chargers. It identifies ConnectX portable backpack power supplies as an exception with a two-year term. Check the product-specific warranty rather than extending the FAQ wording to every Makita product or region.
DEWALT: hand-tool wording is not cordless-tool coverage
DEWALT’s limited lifetime warranty applies to specified hand tools that state they carry it; it is not a general lifetime promise for cordless power tools. The warranty wording also caps coverage for electrical and electronic components at one year. Use the exact cordless model’s warranty to determine its coverage.

- Start with the exact tool and kit. A brand-level headline may not apply to a particular model, battery, charger, or bundled kit.
- Compare batteries separately. Bosch gives 18V batteries a shorter term than tools and chargers, while Milwaukee’s general five-year power-tool term excludes cordless battery packs.
- Put enrollment deadlines on your calendar. RIDGID LSA registration is due within 90 days; FLEX’s five-year extension requires qualifying registration within 30 days.
- Check purchase eligibility and documentation. Confirm whether the seller qualifies and whether you need a receipt, UPC, serial number, or approval. RIDGID’s program has product and purchase requirements, and FLEX requires proof of purchase for registration.
- Read ownership and replacement rules. RIDGID’s LSA is for the original owner, and a replacement may need its own registration. Do not assume coverage transfers unless the applicable terms say so.
- Review exclusions and service logistics. Ordinary wear, misuse, non-genuine parts, unauthorized repairs, and return-to-service-center requirements can affect the practical value of coverage.
- Use the terms for your region and purchase date. This comparison is based on US-focused materials, with Milwaukee and FLEX pages also covering Canada. Warranty language may change and differ across jurisdictions.
What warranty length cannot tell you
A long published term does not establish how likely a claim is to be approved, how quickly a repair will be completed, or how customers rate the service. The reviewed warranty materials provide no comparable claim-approval, turnaround, or satisfaction statistics. Judge the written scope and the steps you must complete rather than assuming one brand will resolve claims faster.
