Needed to charge my LED flashlight battery, due to a faulty charge circuit in the flashlight. Now I have spare batteries for my flashlight. Accept different sized rechargeable batteries to. ### ⭐⭐⭐⭐ Great deal, battery doesn't last as it long as it should *by D*** on June 4, 2024* I bought these as a replacement for my Fenix 3500mAh. These are supposed to be 9900mAh which I didn't really expect. I installed it in my caving light and turned the light on to test it. It did great for 7 hours and then dimmed to unacceptable levels. My original Fenix if good for 10+ hours. I am happy with the purchase and would have given them 5 stars of they had held up longer. I would recommend them and would purchase them again. ## Frequently Bought Together - 4 Pack 1￵8￵6￵5￵0 Rechargeable Batter￵y 9900m￵A￵h W￵i￵th 18650 Battery Charger,Universal Smart Charger for 3.7V Rechargeable Battery 21700 14500 10440 - Victoper LED Flashlight 2 Pack, Bright Tactical Torch High Lumens with 5 Modes, Waterproof Zoomable Flash Light for Outdoor, Gifts for Camping Essentials Gear --- ## 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.sk/products/593243710-4-pack-1-8-6-5-0-rechargeable-batter-y](https://www.desertcart.sk/products/593243710-4-pack-1-8-6-5-0-rechargeable-batter-y) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-22*
