Article battery for Apple iPhone 11 Pro 3046mAh (CoB)

Replacement battery cell without flex cable marked as CoB (cobalt battery), designed for Apple brand phones.

The quality of batteries can significantly affect the performance and lifespan of devices. Batteries marked with the brand (CoB) - Cobalt Battery - are characterized by a high cobalt content.
Why is cobalt content important? Cobalt is a key element in the production of lithium-ion batteries, which are the primary source of energy in many modern devices. Its higher content in batteries provides higher energy density and improves overall battery performance.
By using batteries with a high cobalt content, we ensure not only the long-term performance of your devices, but also increase their lifespan and reliability. Thanks to this quality, you can rely on our products to fully meet your needs and expectations.

Due to EU regulations, batteries are not shipped fully charged to 100% capacity. After installing the battery, it is important to first complete one full charging and discharging cycle for calibration and proper functioning of the new battery.
