Review on 🔋 HQRP 2200mAh Battery: Compatible with iRobot Mint 4200, 4205, Braava 320, 321 & More - Ultra High Capacity GPHC152M07 for Robotic Vacuum Cleaner by Jennifer Salazar

My Mint 4200 is called "Little Joe" - My Neato XV11 is called "Hoss". Note that the replacement batteries listed on Amazon for the Mint 4200 range from 1200mAh to 2200mAh. This product is a 2200mAh version, so it will last almost twice as long as the 1200mAh version all other things being equal. In fact, my spare battery lasts longer on a full charge than the original factory battery. The replacement is easy to make. This is a great replacement!
