Then It started giving error codes. I traced the problem to the connectors. They were poorly aligned and would not make proper contact unless excessive pressure was put on the battery. Once assembled it wouldn't work. Sending it back for a refund. Poorly assembled. ### ⭐ Would not take a charge. *by R***M on Reviewed in the United States on October 28, 2019* This battery was easy to install, but after one use it would not charge. I kept getting error codes. Through research on that error code, I found that the problem was due to it not being an official IRobot Roomba battery. I tried cleaning the area and reinstalling it. Still won’t charge. Unfortunately I waited too long to install it because my old battery was doing ok and I just didn’t get around to it. My window to return it has closed. I want others to be aware that this battery DID NOT WORK with my Roomba. ### ⭐ Not working for me *by J***T on Reviewed in the United States on January 24, 2020* After about 8hrs of charging, the battery I received is good for only about 15 minutes of vacuuming, then it's empty. Leaving my Roomba off the charger results in completely drained/dead battery after a few days. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/122891933-upgraded-to-3-8ah-14-4v-replacement-battery-compatible-r3](https://www.desertcart.sk/products/122891933-upgraded-to-3-8ah-14-4v-replacement-battery-compatible-r3) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-13*
