How can I reach their customer service?** A: Well. I got 2 but none of them works. Please let me know if you find out. Amazon should get rid of this seller. **Q: How long does the charge hold while not in use?** A: Lithium-Ion has a very high retention at mid-charge. Generally it loses around 5-10% charge in the first 72 hours until it hits 90%, then around 2-3% per month. Once it drops under 20%, it will begin to die out rapidly within around 2 weeks. **Q: Are these batteries supposed to reach temps of over 140+ degrees when charging? I'm afraid they're going to catch fire.** A: No, that is too hot. About 120 is as hot as they should get. You should be protected against a fire like the seller pointed out although it’s not a safety valve it’s a fuse that will break but can’t be reset. But if the battery is getting that hot in the first place it make me question the quality and worry that the fuse won’t work. The seller is completely wrong about it being impossible for the battery to catch fire, it’s rare but definitely possible. Also fire aside getting that hot is going to severely shorten the battery’s lifespan. **Q: What is the weight in grams of a single aaa battery?** A: Not sure but light them 1.2v recharge and regular 1.5v battery ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lasts a Long Time *by S***E on September 21, 2025* I can’t believe I’ve been using my batteries for over 4 years on a regular basis in a fan. They take a little longer to charge now. These would probably be equivalent to an EV with 200,000 miles on it. ### ⭐⭐⭐⭐⭐ Worked well in a flashlight *by J***N on May 19, 2026* Worked well in a flashlight. ### ⭐⭐⭐⭐ So far, so good *by P***E on May 3, 2021* Too soon to rate durability. Charging circuitry with indicator light is built into the battery. Batteries were charged when received, which is a plus. Packaging should include some kind of charging instructions. The first time I plugged in the charging cable, I didn't notice the indicator lights and thus had no idea how long to charge. The second time, the indicator lights flashed red, and I had no idea what that meant. I assumed it meant that the batteries were charging, which turned out to be correct, and let them charge; eventually, the the light was a constant red, which apparently means the charging is complete. Can you then leave the batteries to trickle charge, or do you have to remove them before you damage them? Who knows? I'm removing them to be on the safe side. No information on warranty. There is an email address for questions, with a top level domain of cc, which means the Australian Cocos Islands. Good luck visiting their headquarters. The product specs out well, the price seems good for what you get. User and warranty information is lacking, and manufacturer has little or no U.S. presence. I'm tentatively rating this 4/5 for the design, but questions abound; so caveat emptor. ## Frequently Bought Together - Lankoo USB D Lithium ion Rechargeable Battery, High Capacity 1.5V 12000mWh Rechargeable D Battery, 4 H Fast Charge, 1200 Cycle with Type C Port Cable, Constant Output,2-Pack - Beech Lane RV Fridge Fan, Patented, High Power 3,000 RPM Motor, Easy On and Off Switch, Multiple Side Vents Increase Airflow, Durable Construction, Efficiently Cools Refrigerator (Natural) --- ## 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.ae/products/225919754-d](https://www.desertcart.ae/products/225919754-d) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-24*
