I have an 1800mAH battery in my Null 2 gaming handset, so I ran it completely flat, then plugged it into a USB Power Bank with a USB Power meter in the circuit. The battery took about two hours and ten minutes to fully charge using a USB C cable. The initial charge current was about 1.25A, which gradually ramped down over time to about 400mA until the battery was charged. The power meter showed that it took about 1950mAH hours to charge the battery. The time that any particualr device takes to charge the battery will depend on the output power of the charger, the charging circuit, the initial charge state of the battery and whether the device is being used whilst its being charged. If it is, then the battery will take longer to charge. Hope that helps :-) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome *by D***Y on 2 November 2025* Great batteries amazing quality and read as the correct mah ### ⭐⭐⭐⭐⭐ used this to replace battery in hyperx cloud 2 wireless headset *by D***B on 26 November 2024* This works great and boosted the longevity of the talk time.

So a good replacement ### ⭐⭐⭐ Watch Out for the Polarity ID Colour !! *by A***C on 24 September 2025* Why these batteries have the connector plug fitted the opposite way around to all of the connector leads available, is a bit of a mystery. And a massive pain in the chunks. ## Frequently Bought Together - EEMB Lithium Polymer Battery 3.7V 1800mAh 963450 Lipo Rechargeable Battery Pack with Wire JST Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase(1) - HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions - elechawk 10pcs Upgraded Tiny Whoop JST-PH 2.0 Male and Female Connector Cable for Battery JJRC H36 H67 Blade Inductrix 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.vn/products/384306794-lithium-polymer-battery-3-7v-1800mah-963450-lipo-rechargeable-battery](https://www.desertcart.vn/products/384306794-lithium-polymer-battery-3-7v-1800mah-963450-lipo-rechargeable-battery) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
