Maximize Your IRobot'S Efficiency With SPARKOLE'S 5300MAh Extended Life Lithium Ion Battery For Roomba 500-800 Series Review

Although this was a optimal replacement to the original battery, this lasted approximately 10 months before not holding a charge of maybe 45 minutes. It started off great, lasted for up to 3 - 4 hours per use. then out of no where maybe would get 45 minutes and i would have to hunt down the Roomba. I've since got a replacement not knowing it was the exact same one. lets see how long this replacement lasts.

After about 6 months of good use and enjoying my roomba, the roomba would display a dead battery indicator, and constantly boot cycle when I would reposition it on the charger.I removed the battery, and decided to test the voltage. Any sane person designing a lithium battery pack will contain an electronic "brain" that manages the charge level of the batteries within. These electronics make sure that the batteries are well-maintained, so that your roomba doesn't spontaneously combust as it…

I bought the battery pack in March 2022, and my return window was closed in August. Now, my room a starts cleaning as usual, but abruptly stops in the middle of the room after about 30-40 minutes with no juice left in the battery. At first I thought it was a one time fluke, but it fails to run for at least an hour, and I always have to hunt the robot down under beds, couches etc.Update: Seller reached out to me and sent a new battery with no charge, even though the warranty had expired. Seller…

Battery worked great. Purchased almost exactly 1.5yrs ago and now battery will not take a charge. Does not register any voltage at any terminals. No continuity either. Easily doubled the run time of our Roomba but now needing replaced again.

After installing the battery and letting it charge for 20 minutes, it would repeatedly indicate "Charging error 1" on my Roomba 655. After a bit of research I fixed it by cleaning the charging contacts on the home base / docking station and on the bottom of the Roomba using steel wool and dry cloth. I also made sure the contacts on the battery were clean (with dry cloth).This battery probably draws a bit more current from the charger than the Ni-MH batteries, which I expect leaves it more…

Purchased it Aug 2021, it just died and it is July 2022. So 11 months is kinda lame. But, it worked great until it died. Fits perfectly, easy to install. But, I'd like it to have lasted longer

I purchased this battery for my Roomba 860 and 960. Longevity is an issue as it died in less than two years. It will not take a charge even switching it to a different vacuum with a different charger. On one unit, it will give an error and no signal on the other.

I'm hacking my Roomba 655, so I picked up an SCI interface cable to read data out.After 3 times fully charging and using the roomba for 1 1/2-2 hrs each time (until the "Charge roomba" voice prompt), here's the max charge data as the charge finishes:bat: min 263 sec 18 mV 16866 mA 1156 tenths-deg-C 358 mAH 2696 state 8 mode 3bat: min 263 sec 19 mV 16866 mA 1164 tenths-deg-C 358 mAH 2696 state 8 mode 3bat: min 263 sec 20 mV 18285 mA 133 tenths-deg-C 416 mAH 2696 state 8 mode 3bat: min 263 sec 21

The life of the battery was a little over a year and a half. I'm a little disappointed that the battery stopped holding it's charge after this short of a time period. I thought the battery should have lasted a minimum of two years.

Runs well for about 12 months, then stops charging. We only used it every other week, so we did not get very many cleanings in before I had to start looking for a new battery again.

This battery has my Roomba running like brand new. I used to marvel when it ran for hours and did a Grest job vacuuming. I purchased a replacement on here a while ago. It constantly died away from the dock and did not run very long. This Battery is the real deal! Highly recommend! Also got a refresh brush and filter kit. My 9 year old Roomba is running like New!

We suffered a dog poo-pacalypse with our Roomba last December. In cleaning him up, I must have gotten his original battery wet because it wouldn't hold a charge and just beeped uselessly on the charger. We did a lot of research on what replacement battery to purchase and settled on this one after considering reviews over time. It's been several weeks since we installed the battery-- it seemed like it might be too big, but after screwing the battery cover down, it fit perfectly-- and the Roomba…

Seems to work fine in my Roomba thus far. Can't speak to life or longevity as yet, but my guess is it will do the job. May not be eligible for return or exchange.

What’s there to say about a battery? **This** battery seems to be doing a good job. The Roomba functions well three times a week, the battery charges properly, and I am happy with this product. It was easy to install.

I bought this several months ago and have been using it since. Install was pretty basic. So far, it is running longer than the OEM battery. So far, I would recommend.

Super easy to install. If you follow the instructions about how to charge the battery your Roomba will run longer.Charge it fully and then run down fully 4 times and then set it on your schedule. The battery will last longer over the 4 times you train the battery. My run time lasted 3+ hours the second time I charged it after 2+ hours run time the first time. I will revisit this later but in my experience it works out better than the original battery ever did.

I have ordered one of these before as well. They last 1-2 years in service with a Roomba in my experience.(i dont use my Roomba heavily but probably weekly or twice that). Its easy to install the battery and it charges right up etc. and then your roomba will run for 1-2 hours on a charge (more than it did when it was new actually). You'll have to replace it again in a couple years most likely but its worth it rather than buying a new one.

Battery failed in under a year which is frustrating. It seemed to work well enough for the first half year but then I noticed a consistent degradation beyond that. Look for another option.

Dropped right into an older Roomba. Added at least 30+ minutes of run time to previous technology batteries. May not be as energy efficient as advertised!

I have been running my Roomba 770 CONTINUOUSLY for 7 hours after first charge in order to deep-cycle recharging first few times. I thought it would never stop. Re-charging now for second run. Whew.
