Tenergy 7.2V 2000mAh Replacement Battery for iRobot Braava 380 380t 390 390t & Mint 5200 5200B 5200C – Enhanced Power and Durability! Review

This is exactly what my car needs. And at a significantly lower price. I love my mop and was very sad that it didn't work for more than a minute before needing to be recharged. Now I can wash the whole house in one load again.

The original battery in my iRobot is dead. It was an easy replacement, it fit perfectly and brought me back to life at a great price. I compared prices and this was the best value for money I found. I didn't rate the battery life; Hopefully I won't know the answer to that question for a few more years.

This battery will charge and discharge just like the original battery. I use a vacuum cleaner at least 2-3 times a week and it works for at least an hour or even more. I didn't get it right, but I'm happy. It installs quickly and easily. I have nothing but good things to say about this battery so far.

New product can work for 4 hours. I almost never use this robot... maybe once every 3 weeks. Either way, this battery lasts 4 hours new, just like an OEM battery. At eight months, we'll be lucky if he gets out of the fridge and into the sink before he dies. If we go back to OEM, even at 3 times the price, it lasts 3 years, just like the original battery. Much luck.

The OEM battery that came with the Braava Jet lasted me almost 2 years (with very little use). When I replaced it with one of these, it only lasted a year, but the price savings more than made up for the limited lifespan. This battery costs up to 4 times less than an OEM (Original Equipment Manufacturer). Great purchase and I will use the same again if my car lasts long enough.

Product ordered at the end of July 2020. Worked fine once installed but battery life started to drop after a few months to the point that the iRobot 380t only ran for about five minutes before the low battery indicator started flashing and the cleaning cycle stopped. Changed the battery today (6/1/21). So if you measured generously, maybe four months of life. I used an average of 4-5 times a week and only once a day. So the lifetime is maybe 80 cycles.

For new Brava/Mint this might work. But for me, the older Mint 5200, this robot doesn't work that well with a non-original battery. A few days later it stopped charging from the docking station, I had to charge directly. Then this direct charge failed. The Mint 5200 screamed the entire time it was charging (as if it was being unplugged and then plugged back in) this indicates the circuit is open-closed-open-closed-open and so on when charging this battery will. I called iRobot, they said my…

The brand new battery when inserted into the Braava 380T robot causes an episode of "My battery is low weak” beeps this will keep bugging you until you unplug the robot from the power source. Of course, without a power supply, the battery will not charge. You can override/reset Braava's beeping by pressing and holding all 3 buttons simultaneously until the beeping stops (about 10 seconds), but after about 5.10 minutes the beeping will resume. You can charge the battery by repeating this process
