I tried everything from deep cleaning it, cleaning the charging contacts, cleaning the docking station, emptying everything, and manually placing it slowly on the charger. Nothing would make a difference, it would just flash quickly and never take a charge.After installing this battery (which was extremely easy) i was able to turn on my vacuum, it automatically reconnected to wifi, and worked as it did on day one. It holds a charge perfectly and charges without issue ### ⭐⭐⭐⭐⭐ Works as should. *by on Reviewed in the United States January 1, 2026* Battery worked. Easy install and replacement. Been a couple of months and haven't had any issues. Not much else to say. ### ⭐⭐⭐⭐⭐ Plug and Play, working great *by on Reviewed in the United States January 26, 2026* Plug and Play, working great ## Frequently Bought Together - MULS 3350mAh Battery Replacement for Eufy RoboVac LR30 L35 LR20 Hybrid+ Robot Vacuum Cleaners PN:Eufy CMICR18650F9M-4S1P T2996011 - Spare Accessories Compatible for eufy 11S Max, G30, 30C Max, 15C Max, G32 Pro, Robotic Vacuum Replacements: 1 Roller Brush 6 Side Brushes 5 Unibody Filter π™‰π™Šπ™ 𝙛𝙀𝙧 πŸπŸπ’ / π—šπŸ―πŸ¬ π—›π˜†π—―π—Ώπ—Άπ—± - Spare Accessories Compatible with eufy 11S, 25C, 30C Slim Robotic Vacuum Cleaner NOT for Max/G/L Series Replacement Parts Include: 1 Roller Brush 6 Edge Brushes 6 Filter Foam Kit --- ## 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.tn/products/620353330-muls-3350mah-battery-for-eufy-robovac-lr30-l35-lr20-hybrid](https://www.desertcart.tn/products/620353330-muls-3350mah-battery-for-eufy-robovac-lr30-l35-lr20-hybrid) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-02*
