During their operational life, rechargeable batteries in consumer electronic devices such as smartphones, tablets, wearables, laptops, etc. can experience changes that can pose a safety hazard, e.g., swelling, leakages, etc. This disclosure describes techniques that use sensors integrated within the battery to measure battery parameters such as pressure, humidity, chemical composition, temperature, number of charge-discharge cycles, etc. to detect changes in battery condition. Corrective action is taken to prevent battery damage, e.g., by limiting the maximum voltage, charging level, charging or discharging current, shutting down or disconnecting the battery, etc.
