You will have to open the light to change the battery but it gives the light a new life. ### ⭐⭐⭐⭐⭐ Buen precio. *by A***S on January 22, 2026* Funciono perfecto y buena calidad. ### ⭐⭐⭐ Not all 4 batteries were good. One of them didn’t keep a charge. *by S***R on November 5, 2022* The batteries are a replacement for dog collars. I’m a little concerned using them after the one battery didn’t keep a charge. After inspecting the bad battery it was expanded, like it was going to explode. So far the other 3 batteries are good. ## Frequently Bought Together - EEMB Lithium Polymer battery 3.7V 250mAh 502030 Lipo Rechargeable Battery Pack with wire JST Connector for VXI Blue Parrott and MP3 MP4 Speaker-confirm device & connector polarity before purchase(4) - EEMB Lithium Polymer battery 3.7V 2000mAh 103454 Lipo Rechargeable Battery Pack with wire JST Connector for Bluetooth Speaker and Dashcam-confirm device & connector polarity before purchase - elechawk 10pcs Upgraded Tiny Whoop JST-PH 2.0 Male and Female Connector Cable for Battery JJRC H36 H67 Blade Inductrix Eachine E010 E013 --- ## 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.tn/products/280590017-eemb-4pack-lithium-polymer-battery-3-7v-250mah-502030-lipo](https://www.desertcart.tn/products/280590017-eemb-4pack-lithium-polymer-battery-3-7v-250mah-502030-lipo) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
