Do fall detection watches have a long battery life?

The best fall detection watch never requires you to take it off to charge – leaving you unprotected during that time.  That is the Kanega Watch.  The watch comes with four rechargeable batteries – two that fit easily in the watch band and two that stay in the provided custom charger.  At home, the Kanega Watch batteries will last up to 36 hours or longer before having to swap out (because WiFi connectivity drains power slower than cellular).
