Easy to install. The cable is a little long for the Eufy 30C Robovac. Took a little finessing to get it in. But once I figure out a good location, the battery went in easily. Just don't use anything sharp to push the cable down between the battery and the battery compartment. ## Frequently Bought Together - Upgraded 4000mAh N79 14.4V Battery for Eufy RoboVac 11 11S 30 15C 25C 35C Robot Vacuum Cleaner for Ecovacs Deebot N79 N79S Deebot 500 600 DN622, Goovi F007C D380 Robot Vacuum Cleaner Battery - SONGRUI Replacement Parts for eufy robovac 11S, 12, 15T, 15C, 25C, 30, 30C, 35C Slim Carpet Robotic Vacuum Cleaner Hepa Filter Pre-filter Roller Brush Spin Side Brushes Attachment (with Pre-Filter) --- ## 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.co.za/products/670682270-upgraded-4000mah-n79-14-4v-battery-for-eufy-robovac-11](https://www.desertcart.co.za/products/670682270-upgraded-4000mah-n79-14-4v-battery-for-eufy-robovac-11) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-22*
