Hanaix 4800MAh Replacement Battery IRobot Review

Took 2 weeks and failed. Very disappointed 😞Update! Although the 1st battery gave me problems, Hanaix did everything to solve this problem. Very good experience so far! Thank you for contacting me and helping.

I'm very happy with this battery. It breathed new life into my old Roomba. The first one I ordered had a broken clip and couldn't stay in the vacuum. Advised Revain and immediately sent a new one. The return was easy and now everything works.

This battery has a capacity of 4800 mAh. Other batteries say they are 3500 mAh. So mine should have almost 28% more capacity. Not so. I only get 90 minutes of use from this battery. 3500mAh batteries provide 90 minutes of use time. For those looking for the best value for money, you can get batteries from 3500 to 3800 mAh. You save more money on a hit.

Had to replace original purchase as only charged twice then shut down. The second battery was the same, but now 30 days have passed. However, the description states a 365-day limited warranty. I wrote the company a letter and received no reply. I will contact Revain soon to try to contact the seller again. I would definitely not recommend.

Longer runtime than factory battery. Slightly heavier than the original. The user manual recommends fully charging before installation. Use Roomba (1, 2, 3 times) without charging until it turns off, fully charge again, and don't charge until it stops. This is a cycle. Do this 3 times to get the battery working, then you can leave it charging when not in use.

Everything worked fine for the first 12 months. My Roomba lasted almost 1.5 hours on a full charge. After using about 20 times in two months, it now works for about 30 minutes after a full charge. Update: I contacted the seller. He suggested I check a few things and it didn't improve battery life. The seller sent me another battery. I like their customer service. I have to rate them higher.

battery Excellent quality! This brought our Roomba back to life and added power to it. Roomba runs for 45 minutes to an hour with no issues and still has enough power to return to the charging station. Important NOTE! Make sure the metal charging contacts on the base and bottom of the robot are clean. It will indicate that it is charging but will not provide enough voltage if the contacts are dirty.

I bought a battery for my Roomba but it is old and the battery is not the problem. The company delivered and served very quickly, not only did they receive my return without any problems or questions. They really care and ask if I have a problem with their product. If I ever need another battery for anything I will contact them again, very impressed with their service and follow up.

What is the larger battery in the 4000? The costs are higher. day, and to charge it he worked an hour and 15 minutes. It then takes another three to four hours to recharge. If you unplug it and leave it overnight and presumably it was fully charged, plug it in in the morning and it's dead again, it takes another three to four hours to charge it, it won't hold a charge. I wish I could send it back but I can't reach people right now
