It's a drop in direct replacement for OEM part. No compatability issue at all. Has been charging and working just like the original. The long term test will be how many charge discharge cycles it lasts but thus far no surprises!

Bought this battery as a replacement to the stock battery that came with our Roomba. The stock battery is about 4yrs old and run time started to decline. After 25-30mins, our Roomba would stop in its tracks in the middle of a job. I found this replacement and installed it right away. Installation was a breeze. Now, our Roomba can complete jobs with out suddenly stopping. I believe the full charge lasts about hour or so. Which is perfect in our case and what we need it for.

The FirstPower 5.0Ah 14.4V Compatible with Roomba Battery Replacement has truly exceeded my expectations. Here's why I couldn't be happier with this purchase: Effortless Installation: Installing this battery replacement in my Roomba was a breeze. It fit perfectly and was ready to use in no time. No need for technical expertise; it's a straightforward replacement. Immediate Functionality: The moment I switched on my Roomba with this battery, it sprang to life with renewed vigor. It worked flawlessly from the get-go, without any hiccups or issues. It's a testament to the quality of this replacement. Extended Power: The 5.0Ah capacity of this battery is a game-changer. It provides a significantly extended runtime for my Roomba, allowing it to tackle larger cleaning tasks without needing frequent recharges. I love the convenience this extended power offers. Size Matters: I appreciate the thoughtful design that maintains the size compatibility with the original Roomba battery. It fits snugly into the compartment, ensuring a seamless integration that doesn't compromise the aesthetics or functionality of the device. In summary, the FirstPower 5.0Ah 14.4V Compatible with Roomba Battery Replacement has revitalized my Roomba and made it even more efficient. It's easy to install, works immediately, and the extended power it provides is a game-changer. If you're in need of a reliable Roomba battery replacement, this one is an excellent choice. I'm genuinely delighted with the results it has delivered.

The battery fits perfectly and provides a significant boost in runtime compared to the original. My Roomba can now clean my entire home without needing a recharge halfway through. The installation was straightforward, and it charged quickly. I appreciate the added power, which allows my Roomba to pick up more dirt and debris. The only reason I’m giving it four stars instead of five is that I noticed it takes a bit longer to charge than I expected

Exactly as expected for my older-model Roomba. I believe it arrived partially charged, so I ran the Roomba to drain the battery fully. After running it down and charging it overnight, the runtime noticeably improved. It had no issues completing my 1,200 sq ft basement on a single charge.

This replacement battery is nothing but a scam. From the very first day, it failed to work properly; my Roomba ran for a frustratingly short time before discharging completely. Despite its poor initial performance, I was shocked that it completely failed after a mere three months of light use. Now, my Roomba displays "Err 5" and refuses to charge at all, rendering the vacuum useless. This battery is junk and a complete waste of money. Avoid buying this product at all costs, especially since there is no meaningful warranty or support provided. You will be replacing it again in less than a quarter of a year.

Fit great as advertised, working well!

Excellent! My old Rumba (770) works like new—I’m very impressed with this replacement battery. After a full charge, it ran over 90mins before I took it near docking station where it docked perfectly. I highly recommend.

Works as good as the original
