🔋 Powerextra 3.8Ah 14.4V Replacement Battery for Roomba R3 500-900 Series Review

It has been exactly 4 months since I bought this product for my Roomba 650. Everything worked fine for the first month. And the battery life has deteriorated rapidly since then. Roomba ran for 1 minute today. Last month I tried emailing the company for a replacement but got no response. Edit: Customer service sent me a new battery after I gave a 1 star rating. I tried asking for a replacement before a 1 star review and they said I had to send the old one back from the bag first. Seems to be one

This is the fourth time I have bought this particular battery and this is the first time I have encountered a problem. As you can see from the photos, the battery poles are different. The battery with the green insert is newer. Aside from the different configuration, the newer drive on the left is partially obscured by a black finish and is not properly installed. I will never buy products from this company again. When I contacted Revain support they in turn contacted Powerextra and they told…

Pet #3, Roomba, became moody and short-tempered. I often found him morosely and aggressively hiding in the corner of the bathroom just 15 or 20 minutes after cleaning. One day he just refused to start, making confusing demands and blinking dazedly. Furry bunnies from pets #1 and #2 were threatening to overtake us all. This battery has breathed new life into my Roomba! We moved from an apartment to a house and now he has enough energy to drive the entire floor and return to his charging station…

UPDATE: Great company. I posted a review below and they sent me a replacement battery within a week. The new battery works well, worked three days without charging. Very nice capacity. seems bigger than the first battery. Previous Rating: Do not buy. It works well for about 5 months, then it won't hold a full charge anymore. Other reviewers probably rated this when they first received it and I was very happy with this battery at the time. Unfortunately, this feeling is short-lived. Now I keep…

This was my second purchase of the same battery from Powerextra. I bought the first battery in April 2017 and it was empty after 7 months. Okay I am, while anything is possible, I might be unlucky. I ordered another one and... the battery drained even faster after 5 months of use. Contacted Powerextra via email - no response. Now I understand - these guys got so many good reviews because the price of the battery is low and the battery works perfectly for the first 5-6 months. After 6 months of…

Other customers should note that where the instructions state that the battery should be fully charged and discharged 2-3 times upon receipt in order to maximize battery life, this should not be done. Just let Roomba return to its base. For me I got the battery, replaced the old one (which only lasted 10 minutes and then died), charged it (done in a few hours or less) and then let it run. It worked for an hour and then automatically returned to base. But he doesn't come home because the battery

I want to stress the importance of conditioning this battery properly the first few times. You must discharge the battery until it is completely discharged, charge it completely, and then discharge it again. Repeat this again and each time you do this you will see the battery hold more and more charge. It comes with a really good load. I don't know if it was fully charged, but it looks like it was. I used it to clean three large rooms until it ran out of juice. I made sure it was completely…
