Thanks.** A: Don't buy it from Tenergy. I had the battery for about 8 months before it died. It should last at least a year. Their warranty is insufficient and the product is not the quality you would want. I asked them to replace the battery and the politely refused. **Q: What is the warranty on this item?** A: We offer a 1 year warranty on this product. If you have any questions or need technical support, please contact us at amazon@tenergy.com or at 510-979-9969. We would love to help! **Q: will this battery replace the 770 model vacuum battery, and will it run the 90 minutes the original does?** A: Yes. Amazon shows it as a replacement battery for 500, 600, & 700 series. Specs and form match up to my eyes. My experience is that Roomba runs about 90 minutes on it and cleans 1200 sqft with no problem. **Q: Will this work for the 561 model, since folks have mentioned it does not work on some specific models?** A: Yes --- ## 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.hr/products/1146129-tenergy-3500mah-replacement-battery-for-irobot-roomba-r3-500-600](https://www.desertcart.hr/products/1146129-tenergy-3500mah-replacement-battery-for-irobot-roomba-r3-500-600) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
