Abstract

A system for monitoring battery status and estimating battery life including a battery monitor configured to connect to a battery. The battery monitor comprises a voltage detection circuit, a temperature sensor and a wireless transmitter configured to transmit voltage and temperature data measured by the voltage detection circuit and the temperature sensor. The system further includes a remote device operative to receive battery voltage and temperature data from the battery monitor, generate a real-time indication of battery voltage, and generate predicted battery life data.
