TeenPower Upgraded 20V 5.0Ah Battery Replacement for Dewalt 20v Battery 2Pack with DCB112 Charger Combo Set

What It Is

This is a 2-pack of aftermarket 20V 5.0Ah lithium-ion batteries plus a DCB112-compatible charger. Designed to replace OEM Dewalt 20V Max batteries for cordless lawn mowers, trimmers, blowers, and other outdoor power equipment.

Fitment & Compatibility

• Brand/Model: Works with any Dewalt 20V Max tool (circular saws, drills, impact drivers) and most Dewalt 20V lawn mowers. Not compatible with Dewalt 20V/60V FlexVolt tools.
• Physical Check: Measure your battery bay depth and width. The TeenPower battery is slightly taller than OEM (approx. 1/8 inch) – may not fit tightly in some mower compartments.
• Charger: Includes a DCB112-style charger (input 120V AC) that charges both batteries simultaneously. Works with Dewalt DCB104, DCB107, and DCB115 chargers, but not with older Dewalt 18V chargers.
• Indicator: Has a 4-LED charge gauge on each battery. Press the button to check remaining charge – same as OEM.

Key Things to Know

• Performance: 5.0Ah capacity gives about 25% more runtime vs standard 4.0Ah Dewalt batteries. Real-world mowing time on a 20V mower: ~30-40 minutes per battery.
• Quality: Aftermarket cells (likely Chinese 18650s). Expect slightly lower peak power under heavy load (e.g., thick grass, binding blade) compared to genuine Dewalt. No overheating issues reported.
• Installation: Drop-in replacement – no modification needed. Charge time: ~1 hour per battery (both charge simultaneously).
• Gotcha: The DCB112 charger is a basic 1.5A charger – slower than Dewalt’s 4A rapid chargers. If you need fast charging, use your existing Dewalt charger.

Should You Buy It

If you need affordable spare batteries for light-to-medium lawn mowing, trimming, or leaf blowing and don’t mind slightly less peak power, this 2-pack with charger is a solid budget option. Not ideal for heavy commercial use or high-drain tools like circular saws – genuine Dewalt is more reliable there.
