Blue Star HQ Battery, developed for iPhone models. Manufactured with maximum precision, it is ideally suited for each specific model. A series of tests confirm its safe use. It consists of lithium-ion cells produced with the latest technologies, including laser welding and precise automation. The battery life is rated for 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 power flow between the battery and the phone, displaying the actual charge status of the device with an accuracy of 1%. This prepares the user to connect the charger and prevents surprises from sudden shutdowns. The battery offers multiple protection features: 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 highly durable 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.
