I vape a lot and on high wattage. I charged these batteries four days ago and they are on 70% battery today. I have had LG, Samsung, and MXJO batteries and none compare to the power behind these bad boys. The 3500 mAh sticker isn't a joke either, these have super high capacity. Look no further, they are well worth the money. ### ⭐⭐⭐⭐⭐ Amazed! *by R***L on December 19, 2017* Amazing power cell. I have several and this is by far the best I have seen. Took a while to charge full. I tested in a flashlight. A 800 lum tactical. I ran it on med setting......omg! It lasted 3 solid days and finialy defaulted to low....it ran another 24 hr. on low....it never shut off....I figured if it ran that long I was sold on this brand......Others and even 4 regular non-rechargeable 123's could get even close to two days. I need 123's for an security cam. I found the website that sells them in the usa....16340's. Ordering them right away!!! ### ⭐⭐⭐⭐⭐ Good battery that comes very close to the advertized capacity. *by B***N on October 10, 2016* These are good batteries that have CLOSE to the advertised capacity, which is hard to find. The first two I ordered, tested capacity was 3450 and 3479mAh. I can't speak to the longevity, as I haven't had them very long yet, but I give them 5 stars simply because most batteries you find on Amazon you don't get even close to the advertised capacity the seller list.... so it's refreshing to find some that are pretty close for a change. The only other batteries I've found so far on Amazon that is also good, besides these Orbtronics batteries, was the SunLabz 3400mAh batteries, which actually exceed their advertised capacity by a good bit, getting around 3500mAh out of those.... so I'm going to try out both these Orbtronics 18650 3500mAh batteries, as well as the SunLabz 3400mAh batteries and will update my review in a few months with how they hold up. These will be getting heavy use in my E-Cig IStick TC100.I used an OPUS charger/analyzer to test the capacities, and I've used it to test out numerous different batteries and it gives me very reliable results.... and as I stated, only these Orbtronics batteries and the SunLabz batteries are the ONLY high capacity 18650 batteries on Amazon so that I've found that is even close to their advertised capacities, all other batteries i've tried were well below what they advertise.... so i'd say these Orbtronics batteries are a good deal. --- ## 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.hr/products/15465343-3500mah-18650-high-drain-orbtronic-3-7v-li-ion-rechargeable](https://www.desertcart.hr/products/15465343-3500mah-18650-high-drain-orbtronic-3-7v-li-ion-rechargeable) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
