Review: Great replacement for old s7 battery - I've had my roborock S7 for 2 years and the battery isn't lasting as long. My S7 will only clean on max for 31 minutes. I replaced the battery with this one and I just ran it for 80 Mins on max for the very first test. It's a great replacement. I don't think it's better than the original factory battery but now it's lasting as long as the s7 did when it was new. ## Features - Multiple compatibility: This BRR-2P4S-5200S battery is compatible with Roborock Qrevo S S4 S5 S50 S6 S7 S4 Max S5 Max S7 Max and is also compatible with Xiaomi MI Robot Vacuum Cleaner 1st Generation（Important: Not compatible with Roborock Qrevo,Roborock S8 Maxv Ultr） - Reliable High Capacity S7 Battery: Voltage: 14.4V | Capacity: 6700mA, Dimensions: 137 × 43 × 45 mm/5.39 × 1.69 × 1.77 inches（Lab-Verified Capacity: No Fake Numbers） - 4-pin battery connector: better quality, longer lifespan & safer operation.Note: Swapping middle yellow/white pins causes no functional impact and delivers more stable power output. - Easy Installation: Replace old battery with new one by connecting the cable directly, vacuum back to normal operation. - High Quality For Roborock Q5 Battery: Built-in IC guards against overcharge, overdischarge, overcurrent and overheating; zero memory effect enables hundreds of charge cycles - Customer Support: This product has a 90-day return policy and 365-day Months Warranty.
