2 Pack 40V 5.0Ah Lithium Ion Battery Replacement for Dewalt 40V Battery DCB404 DCB406 DCB407 DCB412 DCB114 DCB116, Compatible with Dewalt All 40V MAX Power Tools DCCS690B DCCS690X1 DCCS690H1 DCCS690M1

What It Is

This is a two-pack of 40V 5.0Ah lithium-ion batteries designed as a replacement for Dewalt 40V MAX batteries. They power Dewalt 40V cordless lawn mowers, string trimmers, leaf blowers, chainsaws (e.g., DCCS690B), and other 40V MAX tools.

Fitment & Compatibility

• Model Check: Compatible with Dewalt 40V MAX battery models DCB404, DCB406, DCB407, DCB412, DCB114, and DCB116. Also fits any Dewalt 40V MAX tool (e.g., DCCS690B, DCCS690X1, DCCS690H1, DCCS690M1).
• Voltage Only: These are 40V batteries—do not use with Dewalt 20V MAX or 60V FLEXVOLT tools; the voltage and connector are different.
• OEM vs Aftermarket: This is a third-party replacement, not genuine Dewalt. Check that your charger supports 40V lithium-ion (most Dewalt 40V chargers do, but older NiCad chargers won’t work).
• Physical Fit: The battery slides into the same port as original Dewalt 40V batteries. No modifications needed.
• What to Measure: Confirm your tool’s battery bay depth (standard for 40V MAX) and that the battery’s latch alignment matches your tool (it’s universal for this series).

Key Things to Know

• Quality & Capacity: 5.0Ah provides longer runtime than standard 2.0Ah or 3.0Ah packs—good for larger yards or heavy trimming. Aftermarket cells may have slightly lower cycle life than OEM.
• Installation: No tools needed. Slide battery into tool until it clicks; press release tab to remove. Fully charge before first use (approx. 1–2 hours with a standard 40V charger).
• Common Gotchas:
  • If the battery doesn’t click in, check for debris in the tool’s battery slot.
  • Do not mix these with genuine Dewalt batteries in a dual-battery tool (e.g., some mowers) unless the manual explicitly allows third-party packs—risk of uneven discharge.
  • The charger included is not a fast charger; expect longer charge times than with a Dewalt DCB107 or DCB115.

Should You Buy It

Buy this if you need a budget-friendly two-pack for light to medium use (e.g., trimming, leaf blowing) and don’t mind slightly shorter overall lifespan compared to OEM. Skip it if you rely on high-demand tools like a self-propelled mower for large lawns, where genuine Dewalt batteries offer better warranty and consistent power delivery.
