Kastar BRAAVA380 Battery (1 Pack), Ni-MH 7.2V 3000mAh, iRobot Mint 5200 Vacuum Cleaner Replacement Battery for IRobot Braava 380, 380T, Mint5200, 5200B, 5200C Floor Mopping Robots

The 380t has gone through 2 OME batteries 3 years. I only use the robot to top up wet floor mopping between cleaning lady visits. Our condo has about 900-1000sf of smooth tile. This new battery lasts at least two cleaning cycles which covers 80+% of the floor on a single charge. It’s still new so the life expectancy will determine if it is truly worth the 5 stars. For the price, it’s worth buying since it costs a fraction of the OME battery. No issues with compatibility or installation.

So far the battery has worked well. We have had it for about a month.

Bought this because it had all the ratings in what I needed. Had to cut the connector off and solder it onto what my shop light had and worked perfectly. Charges quickly and holds a good charge.

DO NOT BUY. First battery I bought lasted a couple charges and would no longer work. I contacted the company and they sent me a replacement right away. Got it yesterday and plugged it in and put it on the charger and the battery won’t charge.

My Brava floor sweeping/washing robot. It was easy to install, works fine. Only used it a couple of times so I don't know long term use.

Only lasted about 9 months. We used it once a week

Got the wrong battery pack (I ordered the wrong one). But I was able to make it work in my Mint 4200.

Worked great but battery lasted 5 months
