However, I bought this in march, and it's dead in July. Take that for what you will. ### ⭐⭐⭐⭐⭐ No reason to buy the 'name brand battery' with this available *by W***R on November 6, 2025* Direct replacement battery in my System76 Lemur 11 Pro. simple to install and took barely any time. I think I would like to see some adhesive pads for dampening like the factory battery came with, but that's a non-issue for the function. ## Frequently Bought Together - RDSJK L140BAT-4 6-87-L140S-72B01 Laptop Battery for Lemp9 System76 Darter Pro 2021 L140CU L141CU L140MU L141MU 2ICP5/50/112 VIA 14, THUNDEROBOT MixBook Air, WOOKING Jiasha ST Pro 7.7V 73Wh 9350mAh - Seven Puppy Replacement Screen for Pro M1 M2 Retina 13.3” A2338 EMC 3578 MYD83 MYD92 MYDA2 MYDC2 MYD83LL/A MYD92LL/A MYDA2LL/A MYDC2LL/A Full LED LCD Display Assembly (A2338 Space Grey) - SEVEN PUPPY Replacement for Air 13" M1 2020 A2337 EMC 3598 MGN63 MGN93 MGND3 MGN73 MGNA3 MGNE3 13.3 inches 2560x1600 Full LCD Screen Complete Top Assembly (Space Gray) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/273540553-rdsjk-l140bat-4-6-87-l140s-72b01-laptop-battery-lemp9](https://www.desertcart.jp/products/273540553-rdsjk-l140bat-4-6-87-l140s-72b01-laptop-battery-lemp9) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-06*
