Speaker for iPhone 6s 1715 mAh Polymer Blue Star HQ
Easy return of products within 14 days from the date of purchase without giving reasonsHigh-quality Blue Star batteries. The automated production process and the use of high-quality components guarantee a much longer battery life than standard counterparts. The batteries were made using the latest technologies, including laser welding and precise automation that eliminate errors and shortcomings that often occur during manual production. Studies have shown that even after 650 charge cycles, Blue Star HQ batteries still showed a capacity of 94% . In the same study, standard batteries reached 75% capacity after only 120 cycles. In the case of standard batteries, it often happens that the Mobile phone turns off despite the 20% charge indicator on the display. Made of high-quality components, the protection board contains a double IC protection circuit, which on the one hand controls the stability of the current flow between the battery and the phone, and on the other hand indicates the real charge indicator of the device with an accuracy of 1%. This means that the user can be prepared to connect the device to charging and will not be surprised by its sudden shutdown. High-quality components and production methods directly translate into safe use. Blue Star HQ batteries use laser welding to fuse the battery cell and the protection plate. The welds are rounded, tight and free of welding residues. The plate is made of four layers of copper with low internal resistance. Each layer has undergone a 10-fold stability test to ensure safe battery operation. One of the main problems faced by battery installers is the FPC tape, which can be easily damaged. For the production of the FPC tape in Blue Star HQ batteries, copper foil with high flexibility was used, which allows it to be bent multiple times without the risk of damage (some standard tapes are damaged even after bending three times!). The tape in Blue Star HQ batteries has passed tests with a tension force of up to 5 kg.
