This was about the battery, not the @eufyThe battery charged right up. Not sure how fast, as I didn't need it right away and let it charge until I did. I charged it sveral times before selling the house and had no issue whatsoever with the battery itself. ### ⭐⭐⭐⭐⭐ great product *by on Reviewed in the United States June 24, 2026* very good quality ### ⭐⭐⭐⭐⭐ Great product *by on Reviewed in the United States May 22, 2026* Five stars ## Frequently Bought Together - NASTIMA Security Rechargeable Battery Compatible with eufy S330 S230 S220 E330 Video Smart Lock 3-in-1 and Smart Drop, 10500mAh Li-ion Battery Replacement - eufy Security Video Smart Lock S330, 3-in-1 Camera+Doorbell+Fingerprint Keyless Entry Door Lock, Smart Wi-Fi Deadbolt for Front Door, App Remote Control, SD Card Required, Chime Included --- ## 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.pe/products/688675675-3-7v-10500mah-battery-for-eufy-s330-e330](https://www.desertcart.pe/products/688675675-3-7v-10500mah-battery-for-eufy-s330-e330) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-20*
