Review: Avoid buying this - I bought it a few days ago and couldn't get around to actually use it. I opened the packet yesterday and found the battery swollen. When i checked return date it was already pass the date by 2 days. Actually I am glad i never got to install it. Could have turned deadly. Also the unit was swollen even more before i disposed it off. Review: Useless - Connected to bluetooth headphone and connected to charger. Charged for about half an hour and then it went off. When I checked the terminal voltage, it showed zero which means the cell are dead. and now its a day past return period, so I cant return it either. very very cheap product, and now, my 6000rs Bluetooth headphone has become useless ## Features - KP 602040 3.7v 500mAh(full capacity) rechargeable battery for Bluetooth speaker, Drone,DIY,Toys etc - Volt -3.7v - Capacity -500mah ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09Q6DSZ9H | | Antenna Location | Drone,Toys | | Battery Capacity | 500 Milliamp Hours | | Battery Cell Composition | Lithium Polymer | | Battery Cell Type | Lithium Polymer | | Battery Weight | 30 Grams | | Brand | KP | | Brand Name | KP | | Country of Origin | India | | Customer Reviews | 3.8 out of 5 stars 10 Reviews | | Item Dimensions | 6 x 2 x 4 Centimeters | | Item Type Name | battery | | Manufacturer | KP | | Net Quantity | 1 Count | | Number of Batteries | 1 Nonstandard Battery batteries required. | | Recommended Uses For Product | Drone,Toys | | Reusability | Rechargeable | | Unit Count | 1 Count | | Voltage | 3.7 Volts | | Warranty Description | 10 days replacement wareenty for manufacturing defect | ## Product Details - **Number of Batteries:** 1 Nonstandard Battery batteries required. - **Brand:** KP - **Battery Cell Composition:** Lithium Polymer - **Battery Capacity:** 500 Milliamp Hours - **Recommended Uses For Product:** Drone,Toys - **Net Quantity:** 1 count - **Voltage:** 3.7 Volts - **Reusability:** Rechargeable - **Battery Weight:** 30 Grams - **Item dimensions L x W x H:** 6 x 2 x 4 Centimeters ## Images ![KP 602040 3.7v 500mAh(Full Capacity) Rechargeable Battery for Bluetooth Speaker, Drone,DIY,Toys etc - Image 1](https://m.media-amazon.com/images/I/81kPmgFGFUL.jpg) ![KP 602040 3.7v 500mAh(Full Capacity) Rechargeable Battery for Bluetooth Speaker, Drone,DIY,Toys etc - Image 2](https://m.media-amazon.com/images/I/81anXwjhBUL.jpg) ## Customer Reviews ### ⭐ Avoid buying this *by P***S on 26 August 2022* I bought it a few days ago and couldn't get around to actually use it.
