Blue Star HQ Battery, designed for iPhone models. Manufactured with the highest precision, it is ideally suited for each specific model. A series of tests confirms its safe operation. Composed of lithium-ion cells, it is produced using the latest technologies, including laser welding and precise automation. The lifespan is 800 charge/discharge cycles. Research has shown that Blue Star HQ batteries still retain 80% capacity after 500 charge cycles. In the same study, standard batteries reached only 75% after just 120 cycles. The battery features a dual IC protection system that regulates the stability of the current flow between the battery and the phone, accurately displaying the device's actual charge status. This ensures that the user is prepared to connect the charger and is not caught off guard by a sudden shutdown. The battery offers multiple protection mechanisms: against overcharging, discharging, short circuits, and thermal protection. It operates efficiently at both high and low temperatures. The package includes mounting tape for easy installation of the batteries. The tape is very robust and has been tested with a tensile strength of up to 5 kg. Specification: Cells: Li-Ion, dual IC protection chip, no memory effect, number of cycles: 800, mounting tape included.
