I am using them in a box mod, running at around 60w on a dual coil RDA. If you know, you know. They last just about a day (I put them in the charger at night, run a different pair of similar rated for the night and swap these in in the morningish time). I will update if they die early but they seem to charge at 1 amp pretty quickly, they're usually around 3.50v when I put them in, couple hours later they're at 4.2v. Happy so far. ### ⭐⭐⭐⭐⭐ Good investment *by M***D on April 27, 2025* There are quality batteries they seem to hold a. Charge well and it lasts a long time. I feel like it was a good purchase! ### ⭐⭐⭐⭐ These seem to be one of the better ones. *by B***E on October 21, 2024* Not perfect, like the rest I've bought, the first charge works for a couple days, then kinda goes meh. I like AWT's much better. They hold a good charge longer. ## Frequently Bought Together - BENKIA 18650 Rechargeable Battery 3500mAh 3.7Volt Flat Top 2 Pack Large Capacity 18650 Batteries for Headlamp Led Flashlight - 18650 Battery Charger, 2 Bay Battery Charger with Smart LCD Display Fast Charge for Rechargeable Batteries Li-ion LiFePO4 NI-MH NI-Cd AA AAA C 21700 26650 13650 16340 18350 18700 RCR123 - DQGG 18650 Rechargeable Battery 3.7 Volt 3500mAh 2Pcs Large Capacity Batteries for LED Flashlight, Headlamp, Doorbells, Toys, Cameras etc --- ## 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.pt/products/572314133-18650-rechargeable-battery-3500mah-3-7volt-flat-top-2-pack](https://www.desertcart.pt/products/572314133-18650-rechargeable-battery-3500mah-3-7volt-flat-top-2-pack) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-03*
