12.6Ah 20V/60V FLEX MAX Compatible with Dewalt Lithium Ion Battery and Charge Combo, with High Capacity Batteries 60 Volt Baterías DCB606 DCB609 DCB612 DCB615(2 Pack MAX 12.6Amp 60Volt Combo)

What It Is

This is a third-party 2-pack of 12.6Ah lithium-ion batteries marketed as compatible with DEWALT’s 20V/60V FLEX MAX platform. It’s intended for high-drain outdoor power equipment like lawn mowers, string trimmers, and blowers that accept DEWALT’s slide-pack batteries.

Fitment & Compatibility

Before buying, confirm your DEWALT tool or mower uses the FLEX MAX slide-pack interface (not the older 18V NiCad or the compact 20V form factor). This battery is designed to replace OEM models DCB606, DCB609, DCB612, and DCB615. However, it is not a genuine DEWALT product—it’s an aftermarket battery. Check that your charger is compatible with 60V packs; older 20V-only chargers may not charge these fully. Measure the battery compartment depth on your mower—these packs are slightly taller than some OEM equivalents due to the higher capacity cells.

Key Things to Know

• Capacity vs. weight: At 12.6Ah, these are heavy (likely 2.5–3 lbs each). They’ll extend runtime significantly but may unbalance a handheld trimmer.
• No genuine DEWALT warranty: Third-party batteries often lack over-discharge protection or cell balancing found in OEM packs. Monitor for swelling or overheating.
• Charger compatibility: Works with DEWALT’s 60V MAX chargers (DCB118, DCB104). Using a standard 20V charger may charge slowly or not at all.
• Performance drop in cold: Like most lithium packs, capacity and voltage sag noticeably below 40°F.

Should You Buy It

Buy this if you need maximum runtime for a high-drain mower or blower and are comfortable with the risk of aftermarket electronics. Skip it if you rely on tool warranty coverage, need a lighter pack for handheld tools, or prefer the reliability of genuine DEWALT batteries.
