Enegitech Upgrade 14.4v 4.5Ah Roomba 500 Lithium-ion Replacement Battery for iRobot Roomba 500 600 700 800 Series 535 540 563 565 570 580 610 760 780 800 Cordless Vacuum Cleaner

Brought my old 600 series Roomba back to life. The battery life is really good too. I am deducting a star because I had to put in spacers to get the battery to correctly connect to the contacts. My roomba was reporting an error that I had to look up before I put the spacers in. I don't know if it is because this battery needs to have a slightly lower profile to fit some models or what. Either way I am very happy with the purchase after I fixed the contact issue.

This works ok so far. Many times when my roomba docks I get an error message and have to reseat the battery before it will charge.

Great battery, so far its working great. Enables Roomba to run for about 1 hr and 20-30 minutes on a single charge. Happy my Roomba is alive and well again :). Battery was fully charged and operational upon delivery, Roomba ran for 1 hr and 30 minutes before needing to be recharged. Would highly recommend. Will update review if any problems arise.

I purchased one of these to replace the stock battery that had come in my Roomba. It seemed fine out of the box and worked great for about a month. However, after that first month, the Roomba will no longer charge and will say "charge error (1)" repeatedly. If you look on the Roomba Website that error indicates something wrong with the battery. I would not recommend this product.

It didn't work for me and I tried everything.....

We were very satisfied with the product. It arrived in a timely manner and charged very well.

i need to remove the top plastic cover to make the contacts reach but after that works great.

Easy to install. Works great!
