2 Pack 12000mAh High Capacity DCB206 Replacement for Dewalt 20V MAX Battery 12.0Ah and DCB107 Charger Combo Compatible with Dewalt 20V Battery Lithium DCB207 DCB204 DCB200 Power Tool (3Pack)

What It Is

This is a 3-pack set including two 12.0Ah (12,000mAh) high-capacity replacement batteries and one DCB107 charger, designed to power any 20V MAX Dewalt tool—including lawn mowers, trimmers, blowers, and chainsaws.

Fitment & Compatibility

• Voltage: Must be 20V MAX Dewalt tools (NOT 18V NiCad or 60V FlexVolt).
• Model numbers: Compatible with DCB200, DCB204, DCB206, DCB207, and all Dewalt 20V MAX tools that accept slide-pack batteries.
• Physical fit: These are aftermarket replacements, not OEM. The slide rails and latch dimensions match genuine Dewalt packs, but the plastic shell may be slightly thicker. Test fit in your mower’s battery compartment before use—some tight-fit mower decks (e.g., DCMW220) may require slight filing.
• Charger compatibility: The included DCB107 charger works with all Dewalt 20V MAX batteries. It is a basic charger (no Bluetooth or fast-charge features).
• What to measure: Compare length and width of your existing battery (roughly 5.5" x 3.5") to ensure clearance.

Key Things to Know

• Capacity vs. runtime: 12.0Ah is very high—expect 2–3x longer runtime than a standard 5.0Ah pack on a mower. However, the extra weight (~1.5 lbs) can make handheld tools feel unbalanced.
• Aftermarket quality: These are third-party cells (likely Chinese 18650s). They lack Dewalt’s over-discharge protection and may have shorter lifespan. Expect 300–500 charge cycles vs. 800+ on genuine Dewalt.
• Installation: No tools needed. Slide battery onto tool until latch clicks. If it doesn’t click firmly, the contacts may not align—check for debris or warped plastic.
• Common gotcha: The DCB107 charger is slow (2–3 hours for a full charge). For faster charging, use a Dewalt DCB118 or DCB104 charger (sold separately).

Should You Buy It

Buy if you need maximum runtime for a large lawn mower or heavy-duty trimming and are okay with aftermarket risk (shorter lifespan, no warranty from Dewalt). Skip if you want OEM reliability, fast charging, or a lighter battery for handheld tools—stick with genuine Dewalt 5.0Ah or 6.0Ah packs.
