Review: good battery for a good price - I've had these 3 month and can confirm they outlast the 4ah by about twice. only down sides are they weigh a little more so overhead drilling etc is more strain ( to be expected ) and they can overheat and stop working as they did when using on my ripsaw to rip up wet 8x2. once they cool down they work again so clearly a safety feature for the battery cells. so maybe a good thing for over all battery life. they work in all my 18v tools including my wet/dry hoover. Review: Long charge hold - These batteries are great, they charge very fast on a DeWalt specific charger, hold there charge for ,in my estimation, a significant time slot ,all dependant on what work is being carried out of course, I've had them empty of charge and within less than 15-30 mins, fully recharged,can't go wrong with a few spare one's in the tool box. ## Features - 18V Actual capacity and top A grade lithium-ion battery cells provide 3x more runtime, 3x longer lasting charge than standard lithium-ion batteries. - Compatible with_Dewal_t 18V MAX devices.Automatically switch voltage when you change tools.(Perfectly Fit all 18V Li-ion Battery Chargers ✚ Replacement for 18V Lithium Battery.) - Charging faster ✚ When you press the button, 3 LED indicators show battery charge and usage levels. - Built-in circuit protection ensures both safety and stability. ✚ No memory effect,can be store, charged or discharged as needed without loss of capacity.(CE/ ROHS / PSE certificate.) - 2* 9.0Ah Replacement for DCB184 18V Battery + 1* User Manual + Excellent Service:(Free refund or replacement for ONE year !!) & (24*7 hours prompt after-sales service.) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Y393DFF | | Antenna Location | Power Tool | | Battery Capacity | 9 Milliamp Hours | | Battery Cell Type | Lithium Ion | | Battery capacity | 9 Milliamp Hours | | Battery cell composition | Lithium Ion | | Best Sellers Rank | 257,654 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,458 in Cordless Tool Battery Packs | | Brand | QUPERR | | Brand Name | QUPERR | | Country of Origin | China | | Customer Reviews | 4.2 out of 5 stars 95 Reviews | | Item Weight | 259 Grams | | Manufacturer | QUPERR | | Model Name | dcb184 9A | | Model Number | dcb184 | | Product Warranty | one year warranty | | Recommended uses for product | Power Tool | | Reusability | Rechargeable | | UPC | 767912273983 | | Unit Count | 2.0 count | | Unit count | 2.0 count | | Voltage | 18 Volts | ## Product Details - **Battery capacity:** 9 Milliamp Hours - **Battery cell composition:** Lithium Ion - **Brand:** QUPERR - **Recommended uses for product:** Power Tool - **Unit count:** 2.0 count ## Images ![9.0Ah*2 18v（20v MAX） Li-ion for Dewalt - Image 1](https://m.media-amazon.com/images/I/71EJ51Yz9WL.jpg) ![9.0Ah*2 18v（20v MAX） Li-ion for Dewalt - Image 2](https://m.media-amazon.com/images/I/61ww8TWG6uL.jpg) ![9.0Ah*2 18v（20v MAX） Li-ion for Dewalt - Image 3](https://m.media-amazon.com/images/I/61zJbkHEAhL.jpg) ![9.0Ah*2 18v（20v MAX） Li-ion for Dewalt - Image 4](https://m.media-amazon.com/images/I/61c2p7qFfqL.jpg) ![9.0Ah*2 18v（20v MAX） Li-ion for Dewalt - Image 5](https://m.media-amazon.com/images/I/61r6lOPFebL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good battery for a good price *by D***. on 29 November 2020* I've had these 3 month and can confirm they outlast the 4ah by about twice. only down sides are they weigh a little more so overhead drilling etc is more strain ( to be expected ) and they can overheat and stop working as they did when using on my ripsaw to rip up wet 8x2. once they cool down they work again so clearly a safety feature for the battery cells. so maybe a good thing for over all battery life. they work in all my 18v tools including my wet/dry hoover. ### ⭐⭐⭐⭐⭐ Long charge hold *by P***Y on 10 July 2023* These batteries are great, they charge very fast on a DeWalt specific charger, hold there charge for ,in my estimation, a significant time slot ,all dependant on what work is being carried out of course, I've had them empty of charge and within less than 15-30 mins, fully recharged,can't go wrong with a few spare one's in the tool box. ### ⭐⭐⭐⭐⭐ Good battery test *by J***N on 8 May 2026* Good battery test --- ## 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.jp/products/156194823-9-0ah-2-18v-20v-max-li-ion-for-dewalt](https://www.desertcart.jp/products/156194823-9-0ah-2-18v-20v-max-li-ion-for-dewalt) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-21*
