Introduction
If you're in the market for replacement power tool batteries, you've likely faced the great debate: Makita LXT vs. Dewalt 20V Max. Both are industry giants with loyal followings, and both offer excellent tool ecosystems. But when it comes to replacement batteries, the differences matter — especially in terms of compatibility, performance, and value.
In this comparison, we'll break down everything you need to know to make an informed decision when buying replacement batteries for either platform. And yes, BattGlobal has you covered for both.
Platform Overview
Makita LXT (18V)
Makita's LXT platform is one of the most popular 18V systems worldwide, with over 300+ cordless tools in the ecosystem. Key facts:
- Nominal voltage: 18V (18V DC, ~20V peak at full charge)
- Standard batteries: 2.0Ah, 3.0Ah, 4.0Ah, 5.0Ah, 6.0Ah
- Star Protection: Makita's communication technology that optimizes performance and extends battery life (only on newer models)
Dewalt 20V Max
Dewalt's 20V Max platform powers over 200 tools and is the go-to choice for many professionals in North America.
- Nominal voltage: 18V nominal, labeled as 20V Max (peak voltage)
- Standard batteries: 1.5Ah, 2.0Ah, 3.0Ah, 4.0Ah, 5.0Ah, 6.0Ah, 8.0Ah, 10.0Ah
- FlexVolt: Dewalt's innovative technology that automatically switches voltage when used in compatible tools
Head-to-Head Comparison
Compatibility
This is straightforward: Makita and Dewalt batteries are not interchangeable. Each platform has a unique form factor, terminal arrangement, and locking mechanism. You cannot use a Makita battery in a Dewalt tool, or vice versa.
Winner: Tie — both platforms have extensive tool ecosystems, so choose based on your existing tool collection.
Performance
In real-world testing, both platforms deliver comparable power output. A Makita 5.0Ah battery and a Dewalt 5.0Ah battery will provide similar runtime in equivalent tools of the same class.
- Makita advantage: Excellent power-to-weight ratio, especially with BL (brushless) motors.
- Dewalt advantage: FlexVolt batteries can automatically switch between 20V and 60V for different tools, offering incredible versatility.
Winner: Slight edge to Dewalt FlexVolt for versatility, but Makita's LXT battery line is extremely reliable.
Price (OEM vs. Replacement)
| Battery | OEM Price (approx.) | BattGlobal Price (approx.) | Savings |
|---|---|---|---|
| Makita 5.0Ah (BL1850B) | $79–$99 | $39–$49 | 40–50% |
| Dewalt 5.0Ah (DCB205) | $89–$109 | $42–$55 | 45–55% |
Winner: Tie — BattGlobal offers significant savings on both platforms. Check current pricing here.
Build Quality
Both OEMs produce excellent batteries. However, many third-party replacements — including BattGlobal — are now using the same Grade-A cells found in OEM batteries, with added protection circuits and robust casings.
Tip: Always check that your replacement battery has a BMS (Battery Management System) for overcharge, over-discharge, and short circuit protection. All BattGlobal batteries include this.
Winner: OEM has the edge in consistency, but high-quality replacements like BattGlobal close the gap significantly.
When to Choose Makita LXT
- You already own Makita tools and want backward compatibility
- You value a lighter battery for all-day overhead work
- You're outside North America (Makita has stronger presence in Europe/Asia)
When to Choose Dewalt 20V Max
- You already own Dewalt tools (the most obvious reason)
- You want FlexVolt's voltage-switching capability
- You prefer the wider capacity range (up to 10.0Ah)
- You're in North America (better availability and service)
