Tired of failing batteries? The Battery Tender 081-0172 Wireless Battery Monitor helps you track your batteries health! With the new wireless battery monitor from Battery Tender, you can be alerted to battery issues before they become a problem with messages sent straight to your phone!
It's a great use case: plug this into your battery and any time you want, open an app on your phone and see your battery voltage. It's not that simple, however. The main problem is that this monitor cannot deal with most modern WiFi routers (ones where a single SSID appears on 2.4GHz and 5GHz both). You need to have a very simple WiFi router for this, preferably one from around 2010. Initial setup of the device on an iPhone is clunky because of changes to iOS in recent years (telling the Battery Monitor which SSID to use is very clumsy, as it is with plenty of other IOT devices). Sometimes, my battery monitor just quits refreshing current voltage and then it recovers and I don't know why.
