Glossary
Battery capacity
The capacity of the battery installed in the modem with the corresponding type of power supply (see below).
The higher the capacity, the longer the battery is able to work without recharging, all other things being equal. However, note that the situation of "other things being equal" is almost not found in modern wireless modems. First, different data transmission technologies (see above) have different power consumption; secondly, even models supporting the same standards can differ in power consumption (and battery life) due to design differences. Therefore, this indicator in most cases is purely reference information, and even very similar models can only be compared approximately. When choosing, it is worth focusing primarily on the claimed specs of the battery life (see below).

Operating time (internet browsing)
The maximum operating time of the modem with battery power (see "Power") on a single charge in Internet browsing mode. Such power is typical for Wi-Fi routers, therefore, usually, Internet browsing is supposed to provide access to the World Wide Web for an external Wi-Fi device.
This spec is the main indicator of battery life for any battery-powered modem, because it describes the time of using it for its main purpose without recharging. At the same time, you should know that this indicator is measured under certain "perfect" conditions; the actual operating time depends on a number of factors, including the intensity of browsing, the amount of data transferred, the number of connected devices and the distance to them, the cellular network signal strength, etc. Therefore, in fact, the battery life of the modem may be somewhat lower. Nevertheless, it is quite possible to compare different models with each other according to the operating time stated in the specs.

Operating time (standby)
The maximum time the modem can operate on battery power (see "Power") in standby mode on a single battery charge.
This mode can be described as the standby mode. It assumes that the device is turned on, its operating circuits are powered and ready to respond to an incoming signal or user command at any time, but no data exchange occurs and no features work. This indicator is not as important as the Internet browsing time (see above), but it is also of practical importance and allows you to evaluate the battery life of the device — after all, during breaks between communication sessions, the modem is in standby mode.
