The present disclosure provides devices, systems, and methods for identifying conditions in a battery that predict fault or failure, alerting a user to the condition, and providing solutions to mitigate the potential harm that would otherwise result from the fault or failure. Further provided are battery casing designs for improved safety. These systems, devices, and methods are applicable to batteries generally, and are particularly useful in the field of implanted medical devices for mitigating the dangers of battery faults or explosions occurring within the body.
