With better performance, durability, and 4 times the battery life!
Thousands of users like it!
Why is there a need?
- Lithium technology has been increasingly popular in the rechargeable battery market. Products such as laptops, smart-phones, and tablets all use lithium batteries
- Currently, all iRobot Roomba batteries use Nickel-Metal Hydride (NiMH)/Nickel-Cadmium (NiCd) technology
- Insufficient and decreasing operating time usually after 6-12 months of use
- Memory effect + High rate of self-discharge (over 25% a month)
- iRobot only offers 6 months of warranty
The Lowest Price, The Best Cost/Performance
That's the REAL Cost You Pay for Daily Usage
- Our lithium battery: $69.00/800 charge cycles = about $0.09/cycle
- OEM Ni-MH batteries: $69.99/200 cycles = $0.35/cycle
- Aftermarket Ni-MH batteries: $28.50/200 cycles = $0.14/cycle

This iRobot is the best thing I could have ever purchased🌼 It takes a day or two to get the layout of your home but once it does , it goes like crazy. The app is easy to download you can turn it on and send it to its home from there . If iRobot gets stuck you are notified and it’s easily found . My home has no more dust bunnies and is cleaner than ever. I could never get everything off the floor with a broom or vacuum cleaner!
*I absolutely love this thing for cleaning all flooring surfaces **MyBest.Tools** even does a great job on throw rugs. Highly recommend! Cuts cleaning time in half!*
I have just purchased one of these (it is currently shipping) so was really pleased to find your video. Many of my concerns were the same as yours, especially regarding any safety issues. This really helped me put my mind at rest. Thanks!
Would you still recommend it?
Very helpful as I was wondering about the difference between these types of batteries
Thank you for the review, because of this review I bought the battery.
Thanks for your helpful Info
Looking back, would you still advise this type of upgrade?
Is it possible to put an actual roomba brand li-ion (from a 621 series) battery in an older 500 that takes a Ni-MH?
Should publish the mAh Roomba standard battery is 3000 mAH. What's the Lithium? For those who don't understand mHa is essentially how big the fuel tank is on the battery. My non-lithium replacement is 4500 mAh so 150% of the older battery (or half a long again).
once the roomba has started cleaning unplug the charging dock the roomba will clean until the battery is dead and the roomba will say "please charge roomba"
my 560 will go about 1.5 hours with the yellow NiMh battery
These are awesome. Just upgraded to lithium.
hi whats the best way to charge roomba lithium battery, I know you charge manually can you explain how you charge I don't want to mess up the roomba thanks
On proper Li-On appliance, one should be able to charge it at will, like a laptop, the appliance's charger should know how to deal with a Li-On battery automatically. I say SHOULD because there is post out there and kinda go into the pitfalls of user retrofitting a LiOn battery into a originally not designed for LiOn appliance, and for this IRobot the company doesn't seem to be helpful. In general, I'd say once the appliance is fully charged, I'd unplug it, which maybe a pain if if whole reason of buying a robot vacuum is fully automation. Can use an electrical timer.
how is liion battery? Is irobot going home? Is there any difference with the old ncmh battery while using it? can you advice? What would you share at the end of a year?
Liion last 4 hours, still doing very well after 5 yrs, the old nihm battery is 2 hours. I would advise the liion
The charger is not designed for lithium battery and it may have a high risk of catching fire. Remember lithium batteries are very dangerous if it is not fully certified by iRobot.
good to know
Mine wouldn't working flashing red when inserted
Thank you. Good information.
You can buy cheap timer to charge so you don't overcharge.
man, might as well just vacuum yourself! thanks for the info, was considering buying but may just stay with stock batteries.
could I straight swap NiMh for LiIon and use the same charger or what it the option?
Yes, I've been doing it for 6+ years now. Battery still going 3.5 hrs.
@@PoolarityChannel thank you so much!
@@PoolarityChannel can you send a link to order the lilon battery?
thank you
I charged my new Lithium battery overnight, and this morning it was flashing an error message. Also, there was a flashing "red triangle". Anyone know what is going on? The Roomba was running fine this morning, but I am concerned about the error messages. I'm keeping an eye out for now, but I won't be recharging it, until I know what's going on.
Are you sure its seated securely? Just exchange it if you have any doubts.
Thanks, yes it is. The error message is gone, so I don't know what was happening.
I made my own battery for Roomba out of 8 cells 18650 from old laptop and BMS board. It works fine except one thing: after battery is fully charged after another half an hour Roomba says "Charging error 5". That happens when BMS overvoltage protection disconnects battery from Roomba terminals. So now Roomba feels there is no battery inside and issues that error. But even after that it works 3,5 hours straight.
I don't quite understand how this battery shown in video managed to avoid error message like this...
iRobot says to keep the Roomba 500 on the charging station when the Roomba is not being used. I take it this suggestion is only pertinent to the original NiMh battery but I'm not sure because it is never specifically clarified. It is my understanding that for a Lithium battery, it's not a good idea to keep it on the charger all the time. That is the advice that I've heard for say laptops like a MacBook Pro. It that advice holds true for a laptop with a lithium ion battery, why wouldn't that advice also hold true for a Roomba with A lithium ion battery. I've never heard anyone specifically address this battery maintenance issue with the Roomba. Does anyone have any thoughts on this?
if these Li-on batteries have a good BMS (battery management system) built in, the battery will self disconnect from the charger to protect the battery from over charging. and a good laptop will do the same. the laptop will run off of the power supply and not charge the battery anymore. if the battery drops charge over months of no use, the laptop will re-connect and top up the battery.
@@warrenspink990 for laptops, I was referring the scenario where the laptop is completely OFF, and not being used. Fully OFF; not merely in sleep mode. And while being off, it is plugged in to the power supply. I compromised the battery life of my last MacBook Pro and I think that must have been the reason. The tech guy at Apple thought this probably was the case. I’ve abandoned this 😃 routine and try to keep the battery close to 50% and only plug the thing in when absolutely necessary based on my use patterns and where I am. The battery health of the new battery is good and degrading at a slow to normal rate. As far as my Roomba with the retrofitted LIon battery, I don’t think this battery is behaving properly. If I leave it on the charger it starts freaking out after awhile and starts beeping and flashing various shades of red. If I take it off the charger it seems to not have enough juice when I try and use it. I may need to experiment with a workaround. Say leave it on the charger, wait until it is ‘green’ for awhile, then take it off and wait a few hours use the Roomba and see what happens.
So wait, you can use lithium in a robot that is designed for nimh? That doesn't sound very safe.
5+ yrs, house hasn't burn down yet, supposedly they have safety regulators in the batteries
The battery has a balance board to keep the batteries safe. :)
@@kowasumono Ahh, see that I didn't know. Thanks!
I have got Roomba 600 Series. (Roomba 620 exactly)
I have bought this Li-Ion battery 14,4V 4400mAh
Now (after one month) Roomba shows Charging Error.
I have checked the voltage (load by 10ohm resistor) and it has 16.89V !!!!!!!
Be carefully what are you buying.
You are charging a lithium battery with a ni-cad charger thats why
I have the same error message with homemade battery (took 8 cells 18650 from dead laptop and BMS board), it occurs when overvoltage protection of BMS disconnects battery terminals. I'm not particularly happy with it as battery is not fully charged. More correct way would be to lower current while maintaining 16,8 volts. Roomba instead keeps constant current up to 21 volt! That's why protection takes action. But overall it works fine, I had 2,5 hours runtime even with that highly used batteries. So don't worry about that error too much. It's safe.
Ich kenne diese batterie ich habe der saugroboter roomba 620 only one charge per week the roomba works 3 x per week😂 The roomba 980 works only 1:30 min er pusch mehr mit turbo funktion

FYI the Roomba gearbox is not designed for such a long run time! You will eventually overheat the gears and they will melt the gearbox case where the gear bushings are set in to ,especially as Roomba still have not been able to keep hair and dust out of it,this will add to the build up of heat,sorry but you are going to kill your vacuum running it so long and bear in mind there are very advanced electronics in it and there is NO fan to cool them!
The roomba has a timer; it doesn't run forever on a single session.
Don't run it for 4 hrs straight, run it for 2 hrs, empty the dust, rest it for 15, then go for another 2 hrs. This battery still helps, no need to wait 6 hrs between charges
I instrumented my 560 with 8 thermocouples and a datalogger per your concerns. The highest internal temperatures after 3hrs and 45 minutes when it stopped was 62deg c with a 28deg c ambient. There is no risk of damage to anything at that temperature.
video is trash didnt show amp hours or voltage waste of money and time here also it last just as long as stock
There are a hundred video's that show amp hours and voltage but you cant find one that shows this stuff so well presented and simply explained, took me days to find this. You didn't even grasp about the timer in the machine protecting it, and the batteries are meant to be an upgrade which is why Li-Po was invented and is used extensively. The battery reset procedure is important. I'm guessing you think the earth is flat as well.
