melasta 5000mAh Li-ion Battery for iRobot Roomba 500-800 Series

This is my second battery I have purchased from this company. The last one I bought was in October 2020. I have a Roomba 980. We purchased the first one because I could not believe how much Roomba wanted for a battery. This one let my Roomba run longer. It worked great up until about 2 months ago. The battery was finally giving in. I just placed the new one in today and it is running like a new robot! I am so happy that we got almost 5 years out of the old battery. We run our Roomba about 5 times a week vacuuming 900 square feet. It is very easy to replace.

Summary: I do recommend this battery to others. The capacity is overkill for the 563 due to the 60min clean cycle. If your Roomba can easily find your docking station, then go with a lower capacity. If your Roomba gets lost and is often looking for its dock for more then an hour, then this is the battery for you. Initial Concerns: - I noticed the output voltage was slightly different then NiMh battery. Outcome: It is normal due to different battery type. No issues with the slightly higher voltage and don't expect it to impact the life of the Roomba. Recommendation to Roomba owners: For the 500 series, Roomba I highly recommend taking apart the Roomba if you feel comfortable doing so. The gearbox gets so clogged up with dirt and wears out the plastic gears. When I replaced my battery, I did a deep lean of my Roomba, cleaned out the gear box, and oiled it. Roomba's flawed design with NiMH batteries in my opinion for a consumer standpoint: First off, Roomba has newer models that use Lithium Ion Batteries, so this negative applies to 563 cleaning logic. NiMh batteries gain a memory when discharged to the same point over a number a charges. The 'memory' is referring to a behavior of the battery chemistry and not the Roomba software. The battery forms a 'memory' on how far it drained before charged and then when you exceed that point in the future, the battery starts to cut out. This is why NiMh battries should be discharged before they are charged (usually done by the charger, my assumption is the roomba doesn't do this). After battery capacity will decrease with use, resulting in the Roomba going past the 'memory' point and stopping, asking to be recharged. Considering that the roomba seeks the docking station at 60min as its max cleaning time, buying larger capacity NiMh batteries are a bit pointless because of the 60min docking time creating a pattern that can cause the battery to gain a memory. Lithium-ion batteries don't gain a 'memory' and can be recharge at an time. Experience: Due the the Roomba having a 60min clean time before it starts looking for a docking station, this battery capacity is rather overkill for the 563 series. For this reason, a lower capacity Lithium-ion battery may suit your needs better if your roomba often finds the docking station quickly. I like the longer capacity as it means the Roomba can get lost for an hour or so looking for the docking station while it continues to clean. I think I unplugged the docking station and it ran for more then 4 hours before I stopped it and put it on the station. Due to this being a different battery type, the circuity adapts the Roomba charging behavior to that compatible for Lithium Ion. For this reason, the charge indicator light may not be accurate when charging. With greater capacity comes greater charging times. Will this impact you, likely not. The first charge took me over 4-7 hours, however after that, it only needs to charge what it used up, so charging time wont be as long. Due to battery age over time, I'm expecting to get 3-5 years out of this battery without having to worry about it randomly shutting off like bad NiMh batteries with a memory do. Installation: Very simple for the 563 model. Like 5 screws, remove the bottom, old battery pops out, slide the new one in. screw back together, done. It will be the same installation method for any battery replacement of your model in question. Look up how to change your battery for your given Roomba model before buying this item. Notes: - I didn't dismantle the battery to formally test each cell and there capacity, so my assumption is that the battery capacity listed on the product is correct. Based on how long my 563 roomba ran, I have no reason to question the stated capacity. - Each roomba model has different power consumption behavior. Look at your existing advertised capacity and choose a battery here that is greater or equal to that.

This battery was purchased to replace the original battery in our 5 year old 600 series Roomba. The run time of the original had degraded to less than 30 minutes. This replacement was purchased in late in 2024, but I didn't get to install it until January 2025. Initially the battery worked fine, but the week before Thanksgiving 2025 (after less than 11 months of use) the Roomba refused to charge and was giving an error code. Swapping the battery from our other Roomba into this Roomba confirmed it was a battery issue. The battery is great while it works, but at less than 11 months of service life it is not a good option. I've reached out to the company about a free or discounted replacement and will update the review if I hear back.

I viewed this item with a little bit of trepidation; after all, lithium ion batteries have a questionable reputation. On the other hand, I did not want to be a technical Luddite so I decided to accept the risk and power my Roomba up until the year 2030. This battery drops in, fits correctly, and exhibits no abnormal thermal functionality as far as I can tell. As far as Rumba's opinion; she has never had so much fun before: speeding around the room, able to jump on and off the carpet, and now she makes it back to the dock without difficulty every day.

Good quality and price. New

Initially, this is a great battery. I noticed increased capability from my 630 and it always completed its jobs, never dying from a low battery before ending the job. This was a great improvement over the stock battery. 7 months later, I thought that the battery was dying on me and I couldn't recharge it anymore. After taking the base station apart and looking it over, I found a blown capacitor in the circuit that was causing the problem. I replaced the capacitor and everything is working great again! So overall, this battery has been working fairly consistently for the last 11 months or so and continues to excel with greater longevity in my Roomba. It covers a lot of ground and always seems to make it back to the base station.

Super simple to install and our Roomba is working like new!

Hasta ahora funciona muy bien! Notó tiene más tiempo de funcionamiento. Ideal para varios modelos Roomba. Para 677 fue perfecta!

Was working fine but failed after just 5 months of usage

Una basura…..no sirvió ni el año y ya no carga aún cuando no se utilizaba mucho ya que está en una casa secundaria.
