Written by 5 Minutes for Mom contributor Michelle of Honest & Truly! who received a replacement Roomba lithium battery for review purposes from Lithium Power, Inc. We are compensated, but all opinions remain our own.
We moved this past week. With three floors to our house, two kids, two cats, a husband, and wood floors throughout most of it, I don’t think I’ve cleaned this much in a long time. We cleaned before we moved in we cleaned once we got the furniture in and the movers were finished, and I feel like I’ve been cleaning almost every day since then.

To say that I’m grateful to have a Roomba that makes the vacuuming portion easier is putting it mildly, but poor Michelle (yes, my kids named her after me) is having a hard time keeping up. Her battery just isn’t up to the amount of cleaning that I want to do. Fortunately, I just replaced her battery with a new litium Roomba replacement battery from Lithium Power, Inc., and the difference is significant.
Utilizing lithium batteries is becoming the norm in most electronics because they last longer and hold a charge better. They are pretty much par for the course now for most electronics from tablets to cameras to phones and more. For some reason, my not exactly cheap Roomba still comes with a Nickel cadmium battery, however. Lithium batteries last four times longer and hold a charge for nearly twice as long as traditional batteries. Michelle used to last for about an hour and a half or so before she headed back to her charging base due to a lack of batteries. As I used her more and more, her battery life started dropping off.
Lithium batteries have a much stronger recharging cycle. After 800 charges, they retain 80% of their battery power. I obviously haven’t gotten that far with my charging yet, but given the experience I have with my phone, I fully expect to realize that difference. To me, the most important difference is that I can now use Michelle for well over 3 hours before she gives me that nasty red circle where she’s crying for help. Less time charging means a cleaner house for me!
When I first opened up the package, I was a little taken aback. The Roomba replacement battery was carefully wrapped in bubble wrap, but when I unwrapped it, I was surprised by the almost homemade looking bright colors on the battery. Once I opened up the battery case on my Roomba, I realized that this was merely typical of the batteries, as the Lithium Power Inc lithium battery for Roomba is merely a mirror image of colors from the one that was in Michelle to start.
The most frustrating part of the process in replacing my Roomba battery was the utter lack of instructions from Lithium Power, Inc. I was told to “Please refer to iRobot Roomba’s manual for battery installation.” Although I understand that they may not want to void any warranties for the Roomba or have out of date instructions, I expect more from instructions than that. Fortunately, the iRobot site has an easy visual instruction guide to Roomba replacement battery installation. Using a Phillips head screwdriver and following the iRobot Roomba instructions, I was able to switch out the battery quickly and easily.
One awesome part about the lithium replacement battery is that I did not have to spend an entire day charging the battery before Michelle was ready to go. Although I did allow the battery to charge some, she was ready to go quickly – something that traditional batteries are unable to do. Personally, when I want to clean, I want to clean now, not in 16 hours! These Roomba replacement batteries work for the 500, 600, 700, and 800 series, which covers most of the Roombas out there now.
I can’t be alone in my battery for Roomba declining in power, and the Lithium Power, Inc lithium Roomba battery works beautifully. It was quick and easy to install, and it is doing everything that it says it will. It isn’t cheap – $69.99, which includes shipping – but given that my Roomba is now able to clean for more than twice as long before running out of batteries, it’s a price I’m willing to pay for my sanity and peace of mind. And for more peace of mind, there is a second year warranty for the battery that you can purchase when you order for $10 more.

Hi MICHELLE M!
Nice list, although I think it’s missing a few great models that should be on there. Spending a bit of extra cash on a good robot vacuum is definitely worth it. Robot vacuums are great on hardwood floors, and many of the people I’ve recommended this to have come back to tell me how much they enjoy it, and how much easier its made their cleaning day. If anyone reading this has hardwood or low pile carpeting, I highly recommend picking one up (if it’s within your budget of course).
Nice post, MICHELLE M!
the life of a battery is over 3 hours long
I don’t have one yet :/
It usually lasts about 3 hours give or take 30 minutes.
My Mom has one. I’m trying to win the battery for her. I never asked her how long.
Around 3-4 hours
Our roomba will typically last around 3 hours.
My mom says her battery seems to run out just when she least needs it to! LOL! Usually about 4 months or so.
My Roomba battery currently last about a half an hour.

It lasts about 45 minutes but that is not long enough when you have a big hairy dog that it cleans up after.
About 4 hours usually, a little longer if I’m lucky.
My battery on our roomba last about an hour.
We use our Roomba for about ten minutes per room and watch it the entire time, as we’ve seen it go nuts by the cat food and the puzzle boxes. lol It lasts through five rooms before we put it back, but it’s not slowing down, so… Great battery!
i do not have a roomba but i am going to get one for my birthday!
As soon as i get a Roomba I hope it will last long enough to vacuum the entire house.
Not quite 3 hours for us
I have never owned a Roomba. I would love to win this!

I don’t have one yet.
I am not sure yet, mine is still in the box till we move.

Ours lasts nearly nothing. Really, not even long enough to do the big room any more.
I don’t have a Roomba ‘yet’ but still hoping 🙂 but per review it last 3 hours.
Great website i love it.
We haven’t used our Roomba yet, so I can’t say how long the battery lasts. Thanks for the giveaway!
This would be for my Grandmother, I’m not really sure how long her batteries last but I know she mentioned wanting one of these.
Per an article I found Robot promises that the battery can run for up to 2 hours, and based on our estimates, will last about 400 charges.
I am trying to win this for my mother whose battery died. She doesn’t remember how long it lasted.
Never really timed it to see how long thr battery lasts, all I know is that dreaded light is on way too much which is annoying. I’d really love to have one of these and honestly think they should come with them. Perhaps they eventually will start including the better battery. I would love to have a better battery for mine. I love the roomba and it helps keeps fur up from my eight doggies in between using the regular vacuum. Thanks for the chance to win.
Is that true? Last longer, clean better!
I used Roomba everyday for awhile. With this long lasting lithium battery for my Roomba. I cleaned the trash bin everyday back then. Amazingly, I though 4 hours cleaning is good enough. But, I still have to clean the trash bin next day after 4hours plus Roomba operations. So, I decided to try again on next day. On next day and on next day. I learnt that using Roomba every day and last Roomba operation as long as you can really pay off the investment on premier price we paid for Roomba and lithium battery. My living space is so clean since then.
My sister’s kids looked for the balls underneath the cabinet of TV. Their hands were so clean. That touched my sister to buy one lithium battery for her newest Roomba model 779, even the battery comes with is still working for about one hour operations. She tells me that she always pushes clean button of Roomba whenever she walks out. She feels comfortable that she really keeps her home by daily using Roomba with lithium battery instead of using by weekend only.
I don’t have a Roomba but my sister does. She would love this. I think she said her battery last about 4 hours.
I don’t have a Roomba or a Roomba Battery.
Around 3 hours for us.
I learned The battery lasts a little over 3 hours. WOW! I don’t have a Roomba but would love to take one for a test drive.
Just learned the life of a battery is over 3 hours long…super!!
Per the review, the battery power should last “well over 3 hours”. GREAT!
