Overall Feedback:
83% positive
89% praised for its long-lasting battery life, while 11% experienced shorter runtime
The battery lasts twice as long as the original factory battery and costs less than half the price.
The battery life is great. I ran a cleaning cycle on the entire upstairs and when the Roomba found its way back to the dock more than 90 minutes later the light was still solid green.
The replacement battery has the same 90-minute life as the original.
I expected the battery to last much longer than it did. It died under or around different areas of my house just over a year after I purchased it.
81% liked the durable build quality
I am impressed with the battery pack's build quality as it provided significantly better performance than my previous battery and lasted over 90 minutes on a single charge.
The new battery made my broomba more powerful with its higher amperage.
77% found it easy to install
I recommend trying one of these batteries before giving up on your bot vac, especially if you're thinking of throwing away an older model that isn't working quite right.
83% liked the perfect size and fit
I found a new battery and decided to try it. I'm glad I did.
