I was pleasantly surprised to find this 10 pack from almost the same price as a brand name. Worked exactly the same and saved me quite a bit of money. I am very happy with the quality, too. ## Frequently Bought Together - Cotchear 10pcs 1.5V AG4 LR626 Alkaline Button Battery L626 LR626 LR66 SR626 377 SR626SW Batteries Coin Cells for Watches Calculators Toys - Cotchear 10pcs AG1 Battery LR621 364 Watch Battery 1.55V 364 SR621SW LR621 621 LR60 CX60 Alkaline Button Cell Batteries for Watch Toys Remote - LiCB 20 Pack SR920SW 371 370 AG6 Battery 1.5V Button Cell Watch Batteries --- ## 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.tw/products/458348175-ag4-lr626-377](https://www.desertcart.tw/products/458348175-ag4-lr626-377) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-07-17*
