What It Is

This is a 4-pack of aftermarket 8.5Ah lithium-ion batteries designed to replace Dewalt 20V Max batteries. They power any Dewalt 20V Max cordless tool, including lawn mowers, trimmers, blowers, and chainsaws, offering higher runtime than standard 2–5Ah packs.

Fitment & Compatibility

Before buying, confirm your tool uses the Dewalt 20V Max platform (not 18V NiCad or 60V FlexVolt). These batteries are cross-compatible with models DCB201, DCB203, DCB204, DCB205, DCB205c, DCB205-2, and DCB206. They physically fit all Dewalt 20V Max tools and chargers, but check that your charger’s voltage matches (20V chargers only; do not use with 12V or 18V chargers). Measure the battery compartment depth—8.5Ah packs are taller than standard 2Ah units. Ensure your mower’s battery bay has clearance for the extra height (about 1 inch taller than a DCB203).

Key Things to Know

• Runtime vs weight: 8.5Ah delivers 2–3x longer run time than a 2Ah pack, but adds noticeable weight (approx. 1.5 lbs each). Heavier on handheld tools like trimmers.
• Aftermarket caution: Not OEM Dewalt. May lack built-in cell balancing or temperature protection found in genuine packs. Over-discharge or charging in extreme temps can shorten lifespan.
• Installation: No tools needed—slide onto tool/charger until latches click. Ensure contacts are clean and dry. Do not force into a tight compartment.
• Charging time: Expect 2–4 hours on a standard Dewalt 20V charger (faster on 4A+ chargers). Use only Dewalt 20V chargers to avoid damage.

Should You Buy It

Buy this if you need long runtime for a riding mower, large zero-turn, or heavy trimming jobs and want a budget-friendly alternative to OEM packs. Skip it if you rely on lightweight batteries for handheld tools or need guaranteed OEM safety certifications for commercial use—stick with genuine Dewalt.
