The NOWA 360 system has a battery backup that will keep it operational even during a power outage. The battery is rechargeable and can be charged / discharged several times with no problem. The lifespan of the battery is about 3 years. Even if the battery life becomes null, that would not affect the proper functioning of the NOWA 360 system.

The system checks its backup battery charge everyday. If detecting a low battery, it will announce it, it will charge it and will perform a new battery life test 24 hours later. If the battery has been charged, the error code will be removed by itself.
