Going into Turbo (high blower) really eats into your time on the battery's so two spares are recommended. Not too expensive either. Doing great so far. Had them for about 4 months. No problems. ## Frequently Bought Together - Dong Cheng 18V (20V MAX) Battery, Lithium-Ion 4.0 Ah High Capacity Battery Pack Compactible with DongCheng 18V (20V MAX) Power Tools, Model# FFBL2040 - DongCheng 20V Max Cordless Rotary Hammer Drill, 7/8" SDS-Plus, 4 Application Modes, Brushless, 2.1 Joules, Cordless Demolition Hammer for Concrete, Including 4.0Ah Battery and Charger, 4 Drill Bits - Dong Cheng 20V Brushless Impact Wrench, 515 ft-lbs High Torque, 1/2 inch 4-Speed Cordless Impact Gun with Tool Bag, Easily Removes Bolts on Cars, Trucks, and Tractors, Includes 4.0Ah Battery & Charger --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/479162233-20v-max-battery-ffbl2040](https://www.desertcart.in/products/479162233-20v-max-battery-ffbl2040) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-21*
