Had high hopes, but just requested return...I ordered this for my Roomba 980 with high hopes, but I get charging errors and no increase in run-time. I tried a Roomba reset (per instructions), but does not help.My original battery was about 20 min short of doing the whole home without the "return to base & recharge for 90 minutes", and I thought this bigger battery would be great to get it done without the recharge (which extends cleaning by an extra hour+). However, I saw no increase in run time (maybe even a bit shorter run time than the original 3300mAh battery).I installed it, did a Roomba reset (hold Clean button 10+ seconds), then charged overnight. I got flashing lights on the Roomba the next morning, so I did another reset & charge. I finally ran a clean cycle and saw no improvement in run time over the original 980 battery. Given the charge errors, no better run time, and my worries about having a Lithium battery fire (hear of so many on the news!), I'm returning this and putting my original Roomba battery back in...1DO NOT BUY THIS BATTERYDO NOT BUY THIS BATTERY -I purchased a brand new Roomba 980 and it didn't quite finish cleaning before needing to recharge. The original battery lasts just under 2 hours.I purchased this battery and now I get a whopping 32 minutes out of it. It has been used for just over 2 weeks and has had over 5 cycles as per the the manufacturer.Also - the manufacturer has stopped emailing me now after I told them the battery is no good and I need to return it. Poor battery and lousy customer service.1Must have got a dud...:-( Got this for my Roomba 980, since the OEM battery would only allow 45 min of cleaning before needing to return to base. Read reviews and was excited that this battery would increase cleaning times. I purchased and installed this one, but saw no improvement. My Roomba cleans for about 30 min and recharges for more than 90 min. A typical house cleaning would last for 9.5 hours, 7.5 of those hours on the charger! I tried factory resets and reboots, but with no improvement.I will be investing in a new OEM battery for my Roomba. Hope this gives me a better cleaning-to-charging ratio... 2I can't currently recommend this for the newer RoombasDoes not charge in my Roomba 980. This battery worked very well for three days, at which point the charge was depleted and the Roomba refuses to recognize it as a proper battery for it. My Roomba has been properly serviced and taken care of and I went through the full reset and set-up procedures to get this battery ready, and Charging Error 15 rules the day still. This error is an internal communication error caused by when the Roomba queries the battery and finds something wrong and won't allow it to charge.Positives, Lithium Power answered within 48 hours with a series of procedures to try and get this resolved, none worked, and upon letting them know, they immediately accepted it for replacement. I have purchased another and we shall see if there is something different. However, due to the number of other people claiming the same charging issues, even if the new battery works I won't be changing my rating above 3 stars. Get it right Lithium Power, or stop selling it as a replacement for the newer smarter Roombas which can tell what type of battery is in them.3Last rights for this item.Installed this R9 battery into my Roomba 985 & charged it overnight per instructions. Started running my "Rosie" Roomba every other day to vacuum my 2800 Sq. ft. Home. On the 1st day it ran for just over 2 hours, recharging for 90 minutes & continued to the end of the job. On the 2nd day of vacuuming it ran for 1-1/2 hours before needing recharging, recharged for 90 minutes, vacuumed for another hour & finished. On the 3rd day of vacuuming "Rosie" ran for 45 minutes, recharged for 90 minutes, ran for 38 minutes, recharged for 90 minutes, ran for 20 minutes, and then died. I placed "Rosie" on the charging station for 2 days, started her up for a job & she operated for 18 minutes before passing away. Battery totally deceased. I would advise any future customers to think twice about purchasing this for their Roomba 985.1After so many mixed reviews, I gave it a shot and here's what happened...I ordered this for my Roomba 650 even though there are so many mixed reviews. So after having it for 6 months, here's what I've got for you...It's a great battery that holds about 3 times the charge as the standard battery. Now before everyone starts saying that their Roomba stays on for the same amount of time as it did before, and that they ordered this so it would vacuum for longer stretches of time... The Roomba is designed to go back to the station after a certain amount of time or when it feels it has vacuumed the entire area. This is due to the fact that the dirt bin can only hold so much before it starts losing suction and becomes less efficient. SO, with my OEM battery, brand new, it would get me about 75 minutes of cleaning before Roomba would make her way back to recharge. The battery wasn't good to keep going until it was charged back up. With this new battery, when it goes back to charge, I empty the dirt bin/clean the filter, and then press the clean button and away she goes again. Another 75 minutes of cleaning. Then after she docks again, I can immediately clean and send her off again. I can run my Roomga 650 three consecutive times before her light turns red and she has to be recharged. The battery fit is good and I haven't had any error codes that others have talked about.Hope this helps.5Replacement for old NI-MH for 780 roomba Great Battery. Bought the Roomba 780 3 years ago, NIMH was lasting fewer mins then compared to new. More like 55-60 mins tops with Roomba is out of battery.Used the new battery twice so far, on initial charge lasted up to 2 hours 45 mins with just turning red. According to the included time guide would have lasted another 1 to 1.5 hours. I believe it.Pros-Lighter (gives Roomba a mild acceleration boost, as probably the original acceleration was based on a NIMH Roomba which weight slightly more)-More capacity (original battery last about 75 to 90mins max, had Roomba die with no battery multiple times when it was new, as it does not find its way back or light house doesn't work etc etc). Now it has more time to get back to base, so it can screw up, go in circles go to red battery but hopefully still make it back to base :). Major plus-More environmental friendly than NIMH-No more memory effect-No crazy self discharge ratesCons-Kinda the price for now, until the battery proves itself when it does last over 80% capacity after 1 year use. If that holds true, there is no con for this battery.I am glad companies like lithium inc made this products. Unlike Roomba which wants to make money off of making you buy multiple NIMH batteries. Come on, if they can sell a $800+ model 980, why cant they give you a lithium ion battery with it, at least for high end models. 5Acceptable replacementWe have two 980s and are running these batteries in both of them. The Roomba s run 3 times per week (we have two dogs) plus spot cleaning as needed with each Roomba taking care of about 1250 sq ft of floor.Works as well as factory part but not any better. OEM batteries ran a little less than a year before one died with a bad cell, measured voltage after charging was only 12 Volts. The other OEM battery was at full voltage when replaced but would fade unexpectedly with message that robot did not have enough power to start, stranding the robot away from the charge base. The first set of these replacements ran normally for a little less than a year as well before fading. Both batteries maintain full voltage but fall below operating levels unexpectedly so robot doesn t get back to charging base and has to be carried back. I suspect one of them may be tripping over temp sensor in battery pack or robot as when it stops the robot is rebooting. This most often happens when robot is just finishing a charging cycle (so battery already warm from that) and then resumes the incomplete cleaning run, within a few minutes the robot is rebooting. Nothing really different from originals. I bought a second set of these and so far the robots are back to normal, completing their cleaning cycle and parking back on charge base when done. Run time is back to new battery level as well.Pros: priceCons: only as good as OEM battery, not any better.490 Minute Run Time - Roomba 980 (not much better)I was hoping this battery would run for 2+ hours, but it only runs for about 90 minutes, which is not much better than the original. We have the roomba 980 and it is set to vacuum an 800sqft level of our house with hardwood, tile, and carpet. The floor takes 2 hours for the roomba to vacuum and two charging cycles. We had hopped that this 4400mAh battery get the whole floor done in one pass.3Technical questions need to be addressed (*and have been) before we can know if this is going to last.UPDATE-Based upon the following review (unedited from original) - the manufacturer responded to answer my questions. Indeed they have some circuitry to manage this charging process and use the onboard Roomba circuitry to stop charging so as to protect the lithium battery- (via the thermal sensors, which they apparently co-op and signal when their battery is charged via an embedded microchip in their battery).Based upon this I have revised my rating to 5 stars- The battery has been working very well for me with our Roomba functioning for very long periods of time between charges-HERE IS UNEDITED INITIAL REVIEW. Please see comment from manufacturer in response- thus my above edit.Pretty simple. They are selling a lithium battery for a Roomba. I purchased said battery and it fits into my 500 series Roomba. The Roomba now runs for something like 2 hours without needing to be charged. I would give this 5 stars but do not know how long this is going to last- here is why...NiMH and NiCad batteries are charged using a constant current charging circuit designed to never deliver more current than would damage the battery once its fully charged (or blow it up during charging).Li-ion batteries REQUIRE a constant voltage supply within a fairly narrow window, if your exceeding this you can damage the battery- and shorten its life time considerably.Throwing a Li-ion into charging circuitry designed for NiMH will yield voltage ramps (thats how you deliver constant current)---- and bam- a dead battery is the result after X number of charge cycles....So- I looked into the web site for this manufacturer- they have to KNOW about this, but they don't address it. I have no idea if Roomba is smart enough to figure this out and its all OK- or if this manufacturer is selling a product destined to die or if they designed in circuitry to deal with it and partially rectify the voltage ramp, saving the Li-ion battery.In my mind, I took a chance on this purchase, if it lasts over a year or two- good enough for me 4 stars. If they address this and can tell us its designed to charge safely and correctly (maximizing charge cycles before it dies) then I say 5 stars and they did a great job. Until I can figure out if its designed well, or just designed to fail eventually, I view this purchase as a bet.I bet it lasts at least a year or two for me, I don't use it every day or even multiple times a week, so even a poorly designed battery will probably let me run Roomba for extended periods for a year or two- if thats true and it works for a year or two its worth it to me because for 60 bucks I can run Roomba for 3-4 times as long and it is useful. If you charge it every day and use it every day then I guess you probably find out if they designed this well pretty quickly.It would take a single sentence on the web site for this manufacturer to lay this to rest- either its designed to handle the circuitry in Roomba for charging, or Roomba is smart enough to do it, or its not. Would be nice to know.Until we can KNOW if its designed to work, or just designed to fail - I give it three stars.5Not Designed for Roomba 980While this battery will power a Roomba 980, the Roomba 980 is not programmed for 4.4 MaH. When using this battery the 980 will automatically stop and reset after it has used 3.3 MaH of battery life out of the 4.4 MaH charge. This means it won't return home, and you have to restart a new clean cycle.After buying this battery I then bought the Roomba OEM battery, and all the bugs were fixed. Also, the OEM has comparable to better battery life. I wish I had read this review so I didn't have to be the guinea pig.1Not good for a Roomba 980Despite the claims of the seller, this battery did not work correctly in my Roomba 980. I've had the vacuum almost a year and a half, and after shorter cleaning runs I thought this would be an upgrade. Now my Roomba appears to stop dead in it tracks after about an hour, and does not return to the charging station for a recharge.My typical cleaning job is about 75 minutes, and my old battery would usually need to recharge once to finish the job (lot of carpet). But this new battery somehow makes the Roomba stop and send a "low battery" error for any job over about an hour. The funny thing is that when I retrieve the vacuum and put it on its base, it seems to have about a 25-30% charge. But I also don't get any cleaning maps when it dies in the middle of the job, so I don't even know how much got done. This battery's going back, and I'm getting an OEM replacement from iRobot.1

Indeed they have some circuitry to manage this charging process and use the onboard Roomba circuitry to stop charging so as to protect the lithium battery- (via the thermal sensors, which they apparently co-op and signal when their battery is charged via an embedded microchip in their battery).Based upon this I have revised my rating to 5 stars- The battery has been working very well for me with our Roomba functioning for very long periods of time between charges-HERE IS UNEDITED INITIAL REVIEW. Please see comment from manufacturer in response- thus my above edit.Pretty simple. They are selling a lithium battery for a Roomba. I purchased said battery and it fits into my 500 series Roomba. The Roomba now runs for something like 2 hours without needing to be charged. I would give this 5 stars but do not know how long this is going to last- here is why...NiMH and NiCad batteries are charged using a constant current charging circuit designed to never deliver more current than would damage the battery once its fully charged (or blow it up during charging).Li-ion batteries REQUIRE a constant voltage supply within a fairly narrow window, if your exceeding this you can damage the battery- and shorten its life time considerably.Throwing a Li-ion into charging circuitry designed for NiMH will yield voltage ramps (thats how you deliver constant current)---- and bam- a dead battery is the result after X number of charge cycles....So- I looked into the web site for this manufacturer- they have to KNOW about this, but they don't address it. I have no idea if Roomba is smart enough to figure this out and its all OK- or if this manufacturer is selling a product destined to die or if they designed in circuitry to deal with it and partially rectify the voltage ramp, saving the Li-ion battery.In my mind, I took a chance on this purchase, if it lasts over a year or two- good enough for me 4 stars. If they address this and can tell us its designed to charge safely and correctly (maximizing charge cycles before it dies) then I say 5 stars and they did a great job. Until I can figure out if its designed well, or just designed to fail eventually, I view this purchase as a bet.I bet it lasts at least a year or two for me, I don't use it every day or even multiple times a week, so even a poorly designed battery will probably let me run Roomba for extended periods for a year or two- if thats true and it works for a year or two its worth it to me because for 60 bucks I can run Roomba for 3-4 times as long and it is useful. If you charge it every day and use it every day then I guess you probably find out if they designed this well pretty quickly.It would take a single sentence on the web site for this manufacturer to lay this to rest- either its designed to handle the circuitry in Roomba for charging, or Roomba is smart enough to do it, or its not. Would be nice to know.Until we can KNOW if its designed to work, or just designed to fail - I give it three stars.5Not Designed for Roomba 980While this battery will power a Roomba 980, the Roomba 980 is not programmed for 4.4 MaH. When using this battery the 980 will automatically stop and reset after it has used 3.3 MaH of battery life out of the 4.4 MaH charge. This means it won't return home, and you have to restart a new clean cycle.After buying this battery I then bought the Roomba OEM battery, and all the bugs were fixed. Also, the OEM has comparable to better battery life. I wish I had read this review so I didn't have to be the guinea pig.1Not good for a Roomba 980Despite the claims of the seller, this battery did not work correctly in my Roomba 980. I've had the vacuum almost a year and a half, and after shorter cleaning runs I thought this would be an upgrade. Now my Roomba appears to stop dead in it tracks after about an hour, and does not return to the charging station for a recharge.My typical cleaning job is about 75 minutes, and my old battery would usually need to recharge once to finish the job (lot of carpet). But this new battery somehow makes the Roomba stop and send a "low battery" error for any job over about an hour. The funny thing is that when I retrieve the vacuum and put it on its base, it seems to have about a 25-30% charge. But I also don't get any cleaning maps when it dies in the middle of the job, so I don't even know how much got done. This battery's going back, and I'm getting an OEM replacement from iRobot.1
