The physical dimensions of the 1775-ME4 module are 1.295 by 2.421 inches, and its weight is 1 gram. The standard termination in the battery with an optimum temperature range of -55 degrees Celsius (-67 degrees Fahrenheit) to 85 degrees Celsius (185 degrees Fahrenheit) should be maintained to ensure good battery health and desired performance.

The worst-case scenario in terms of life expectancy is 365 days for the 1775-ME4, indicating the device will be functioning for at least more than a year. The replacement shelf life is 10 years.

In order to retain the best health of the battery, indicators are given which should be paid attention to. A steady red indicator expresses a low battery signal. Always check the battery charges before beginning operation and charge the battery as soon as a red indicator flashes to preserve the life of the industrial PLC 3 memory module would be performed over a longer period of time.
