Abstract: The present disclosure describes a system that monitors an alkaline battery pack to detect low voltage batteries before the low voltage batteries can leak. Battery packs may comprise an even number of batteries, operating in series. The system monitors a voltage over each pair of batteries in a battery pack. For example, a first voltage (V1) may be measured between a first battery and a second battery. The first voltage may be measured between ground and the middle of the battery pack. The second voltage (V2) may be measured between a third battery and a fourth battery (i.e., between the middle of the pack and the terminal). The system then estimates the lowest battery voltage (Vtest) by subtracting the higher voltage divided by two from the lower voltage. The resultant voltage (Vtest) is then compared to a threshold voltage (e.g., between 0.85-1.2 volts). If the resultant voltage (Vtest) is greater than the threshold voltage, then the device is allowed to continue operating.
