2-Pack 6.0Ah Replacement Baterias for Dewalt 20V Max Battery and Charger Combo with DCB102 Dual-Port Battery Charger Fit All 12V/20V OEM Batteries

What It Is

This is a 2-pack of 6.0Ah aftermarket lithium-ion batteries designed to replace DEWALT 20V Max batteries, plus a DCB102 dual-port charger that works with both 12V and 20V DEWALT tools. Ideal for powering cordless lawn mowers, trimmers, blowers, and other 20V DEWALT yard tools.

Fitment & Compatibility

• Battery compatibility: Fits all DEWALT 20V Max tools and chargers, including DCB200, DCB203, DCB204, DCB205, DCB206, and DCB240. Also works with DEWALT 12V Max tools (same slide-on form factor).
• Charger compatibility: The included DCB102 dual-port charger charges both 12V and 20V DEWALT batteries. It does not charge FlexVolt or 60V Max batteries.
• What to check before buying: Confirm your mower or tool uses the standard DEWALT slide-on battery interface (not the older 18V NiCad or 40V/60V systems). Measure the battery compartment—this 6.0Ah pack is slightly taller than a 2.0Ah battery (~1.5 inches longer). Not for use with DEWALT 54V FlexVolt mowers.

Key Things to Know

• Aftermarket quality: These are not OEM DEWALT batteries. Expect slightly shorter runtime and faster capacity degradation over time compared to genuine DEWALT 6.0Ah batteries. Some users report inconsistent charge levels.
• Installation: No installation—just slide onto any DEWALT 20V tool. The charger plugs into a standard 120V outlet.
• Common gotcha: The charger may not charge non-DEWALT batteries reliably. If you have other aftermarket packs, test compatibility first. Also, avoid leaving batteries on the charger for days—aftermarket BMS circuits are less robust.
• Warranty: Typically 1 year (check seller’s policy). OEM DEWALT batteries have a 3-year warranty.

Should You Buy It

Buy this if you need a budget-friendly way to run multiple DEWALT 20V yard tools and already own the tools but need extra runtime. Skip it if you rely on heavy daily use or need maximum longevity—invest in genuine DEWALT 6.0Ah batteries instead. Good for light-to-moderate DIY mowing and trimming.
