The lithium battery went into a 4-year old Robot and was a fraction taller than the original. However, by pressing it down harder, I was able to make it fit my Robot. I am very pleased with the product and the method of delivery.

I bought this battery in Feb 2024 and it worked great at first. It was easy to install and fit perfect, but it lacks longevity.My Roomba has always been able to clean my whole house on a single charge in about 40 minutes and it was able to do so with this battery for about the first 5-6 months. Starting in August 2024, the battery’s charging ability diminished significantly. Roomba started to return to home base to recharge about half way through the job.Now Roomba returns to home base every 7-8 minutes, so it now takes over 2 hours to vacuum the exact same areas. I’m annoyed that I already have to replace this battery and I feel like I wasted my money with this purchase.

Instead of ordering the more expensive battery from iRobot, I ordered this generic and it works fine. I can’t say anything about the longevity because I just got it. The one with my iRobot lasted two years. If this HT TopHinon works less than two years, I’ll update my review.

Got our roomba back up and working!

Battery lasted only 4 months in my Roomba. Then it failed and will not hold a charge.

Works fine at first, completely died and stopped holding a charge after about 1 year.

Battery won’t charge after 7 months, ordered a new one today, i guess for the price i should have expected it.

It made it work
