TWIG personal alarms are designed for protection and safety of people. The durable TWIG devices are built to last years of usage. However, all rechargeable batteries have a limited lifespan and eventually need to be replaced.
The battery capacity decreases as a result of aging and use of device. In the end the capacity may not be any longer sufficient for safety use, even though the device appears to be functioning normally.
To ensure reliable operation of the device in safety use, it is recommended to replace its battery every 3-4 years.
