Airtech Battery Tag-On 11Pro/11ProMax

Airtech Battery Tag-On 11Pro/11ProMax covers one of the most common jobs on an iPhone repair bench in Pakistan: you replace a worn battery in an iPhone 11 Pro or iPhone 11 Pro Max and send the phone back without a battery health warning. These phones read battery data through a small circuit on the battery flex, so a bare cell without the matching flex often triggers the non-genuine battery message in Settings. A tag-on flex gives you the flex side of that circuit, so you pair it with a new cell instead of transplanting the original battery flex board. If your shop does battery changes every day, keep this part in the drawer next to your spot welder. You use Airtech Battery Tag-On 11Pro/11ProMax when a customer’s iPhone 11 Pro or 11 Pro Max drains fast, shows low maximum capacity, or has a swollen battery, and the phone needs a fresh cell. You remove the old battery, prepare the new cell, and weld the cell tabs to the tag-on flex, the usual workflow for bare cells on iPhone 11, 12 and 13 series phones. Spot welding stays a hands-on skill, so keep your welding fixture, nickel strips, and insulation tape ready and keep heat away from the circuit area. Technicians on repair forums report zero volts at the output after a bad weld, so you test the output before you close the phone. One listing covers both the iPhone 11 Pro and the iPhone 11 Pro Max, which keeps your stock simple. You still check the model number and cell size before you weld, because the two phones use different batteries. The iPhone 11 Pro carries model numbers A2160, A2215 and A2217, and the iPhone 11 Pro Max carries A2161, A2220 and A2218, so you match the part to the phone every time. The standard iPhone 11 has its own tag-on flex listing, so you do not order this one for that phone. In everyday workshop terms, this part helps when a customer complains about a charging issue or fast drain, you change the cell, and you still need the phone to report battery data cleanly. It also helps when an earlier shop fitted a cheap battery and the phone now shows a warning in the battery health screen. After the repair you test charging, battery percentage behavior, and the Battery Health screen, and you watch for heat or swelling signs during the first charge. In the wider repair workflow, this tag-on flex sits in the power and battery stage, right after you confirm the fault is the battery and not the charging port or a hardware fault on the logic board. If the phone still shows a charging issue after you fit a good cell, you move on to the charging port flex, the charging IC, and a power supply test, so keep a DC power supply close to your repair bench. For the welding side, pair it with a battery spot welder, a welding fixture, nickel tabs, and battery adhesive from the related battery tools categories at KB GSM Store. For data work, shops that need to read or correct battery condition also look at a battery data corrector such as the Qianli Copy Power, which covers iPhone 11 and 12 series. Treat the tag-on flex as your practical starting point and the data corrector as your upgrade path when you want more control over battery health values. Check the cell and the flex together before you buy in bulk, because battery quality differs between suppliers and a weak cell wastes your welding time. KB GSM Store stocks Airtech Battery Tag-On 11Pro/11ProMax for Pakistani repair shops, so you order the part your bench actually uses, keep your turnaround short, and hand the iPhone back to the customer with a clean screen.
