Put the plastic cover back on the battery pack (just the part that goes into the charger) and set your battery on the charger to see if it will take a charge. If you still only get a red flashing light and the battery won't charge, boost the battery some more. I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts.

Given Apple’s sales issues, dropping the price of the iPhone 15 Plus, or even the existing iPhone 14 Plus, are possibilities. Given that it will soon be more expensive to replace a battery on an older iPhone, a cheaper Plus model becomes more appealing to Apple users with aging phones.

Measure the voltage of a repaired pack and check it again after 24 hours and a few days. If a cell drops lower than another in the pack, then there is fear of elevated self-discharge(See BU-802b: Elevated Self-discharge) Simple Guidelines when Repairing Battery Packs Only connect cells that are matched. Do not mix cells of different chemistry, age or capacity.Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit.Include a temperature sensor that disrupts the current should the pack get hot.Apply a slow charge to a repaired pack to bring all cells to parity.Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly.Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.Check a repaired pack for self-discharge. Intrinsic defects often reveal themselves in an elevated self-discharge. Previous Article Next Article
