DEWALT 20V MAX XR POWERSTACK Lithium Ion Battery (DCBP034)

What It Is

The DEWALT DCBP034 is a 20V MAX XR POWERSTACK compact lithium-ion battery (5.0Ah equivalent) designed for DEWALT 20V MAX tools and equipment, including cordless lawn mowers, trimmers, blowers, and chain saws. It uses pouch cell technology for higher power density and lighter weight compared to standard cylindrical cells.

Fitment & Compatibility

• Tool Compatibility: Works with all DEWALT 20V MAX tools, including the DEWALT DCMW220 (20V mower), DCMBLP (blowers), DCST970 (trimmers), and DCCS670 (chainsaws).
• Charger: Requires a DEWALT 20V MAX charger (DCB105, DCB115, or DCB118). Not compatible with 12V or 60V FlexVolt chargers.
• Deck Size: No deck-specific limit—fits any 20V MAX mower, but runtime depends on mower size and grass conditions (e.g., 5.0Ah capacity provides ~30–40 min on a 20" mower).
• Physical Check: Dimensions are 5.1 x 3.0 x 2.2 inches (same footprint as standard DCB205 but lighter). Ensure battery compartment in your tool is clean and free of debris before inserting.

Key Things to Know

• Power Boost: Pouch cell design delivers 50% more power than standard 5.0Ah batteries, improving torque on mowers and blowers—noticeable in thick grass or heavy debris.
• Weight: Weighs 1.2 lbs (vs. 1.5 lbs for DCB205), reducing fatigue on handheld tools like trimmers or blowers.
• Installation: Tool-free—slides onto any 20V MAX tool’s battery port. No adapter needed.
• Gotcha: Not compatible with older 18V NiCad tools or 20V MAX tools requiring a high-capacity (6.0Ah+) battery for extended runtime (e.g., large mower decks over 21"). For heavy-duty mowing, consider the DCB206 (6.0Ah) for longer run time.

Should You Buy It

Buy this if you want a compact, lightweight battery that boosts power on DEWALT 20V MAX lawn tools (especially trimmers and blowers) without sacrificing runtime. It’s ideal for small-to-medium yards (up to ¼ acre) and users who prioritize portability over maximum capacity. Skip it if you need 6.0Ah+ runtime for large mowers or heavy commercial use.
