My Ecozy robot vacuum had been slowing down and barely holding a charge, so I decided to try a replacement battery before giving up on it — and I’m so glad I did! This rechargeable battery was a perfect fit and easy to install with just a screwdriver and a little patience.After swapping it out, my vacuum is back to running like new. It now covers the whole floor on a single charge again and doesn’t die halfway through cleaning. I’ve been using it for a few weeks now, and so far the battery is holding a strong, consistent charge.If your Ecozy vacuum is acting sluggish or not finishing its cleaning cycles, definitely try this replacement battery before investing in a new vacuum. Great value and solid performance!

Works great and it brought my robovac back to life.

I recently purchased the AHJ Replacement Battery 14.4V for my older vacuum cleaner, and I’m pleasantly surprised by how well it performs. The battery came well-packaged, fully charged, and ready to install. Swapping it out with the old one was simple and only took a couple of minutes.Performance:The power output is solid, and it brought my vacuum back to life with noticeably improved suction and runtime. On a full charge, I get around 30–40 minutes of use, which is on par or better than the original battery. It charges reliably without overheating or making any noise.Build Quality:The battery casing feels sturdy and well-made, with no loose parts or cheap plastics. The connectors fit securely, and everything feels like it’s built to last.Compatibility:This AHJ 14.4V battery was a perfect match for my vacuum model (confirm compatibility before purchasing). It’s also a cost-effective alternative to name-brand replacements, without sacrificing performance.Overall:If you need a dependable replacement battery for a 14.4V device, the AHJ battery is a great choice. It restored full functionality to my vacuum at a fraction of the price of the OEM option. Highly recommended.

Listen, I thought my RoboVac had given up on life. It was moving slower than me on a Monday morning and dying halfway through cleaning one room—classic burnout. But then I installed this AHJ replacement battery and BAM—it's like I gave it a double espresso and a pep talk.Suddenly it’s zooming around the house like it’s in a NASCAR race for dust bunnies. My pets are terrified. My toddler thinks it’s a new family member. And me? I’m just proud it doesn’t give up halfway through anymore.---Pros:Brought my vacuum back from the abyss.Lasts longer than my will to fold laundry.Installation was easier than pretending to read the instruction manual.Now cleans like it has something to prove.Cons:So powerful now, it chased a sock under the bed and never came back.May develop sentience and challenge you for household dominance.Makes other vacuums look lazy.---Would absolutely buy again—if my RoboVac ever slows down. Or if it starts demanding snacks. Either way, 5 stars.

The AHJ Replacement Battery for my imartine d900 was great until it died. It fit my vacuum perfectly and was easy to install, the battery life was shorter than expected. The Battery only lasted 2 years. Additionally, as it came to the end of its life the battery seemed to lose charge quickly. I was hoping for a better lifespan. But, The average lifespan of a robot vacuum cleaner battery is 2–5 years. I'm giving it 4 stars because it did last for 2 years and 2 months.

It works great!! Cheaper than buying a new robot vacuum. What a relief!

Works well. Perfect fit for Deebot N79

The battery got my Eufy vacuum going again! good price, fast shipping, works great!
