How to Read a Motorola Two-Way Radio Battery

Posted by Lisa MacGillivray on Tuesday, April 2, 2024

Understanding the intricacies of your Motorola two-way radio battery is key to ensuring its longevity and optimal performance. Whether you're a first responder, work in the security sector, or rely on two-way radios for daily operations in challenging environments, knowing how to read and interpret the information your radio battery offers can save you time and ensure you're always in communication when it matters most. 

Here’s a step-by-step guide and instructional video to deciphering your battery's details and making informed decisions about its care and replacement.


Step 1: Removing the Battery

The first step in this process is to remove the battery from your portable two-way radio safely. This is essential for accurately determining whether your Motorola two-way radio battery is still under warranty, which could save you costs if a replacement is needed.

Step 2: Understanding the Label

Once you have the battery in hand, take a moment to locate and read the label. This label is a treasure trove of information detailing the battery’s capacity, voltage, and model number. These specifics are crucial for identifying the right replacement or understanding the capabilities of your current battery.

Step 3: Model Number Identification

For instance, the common model number on the above battery is PMNN4808A. Knowing the model number is key to understanding the exact specifications and compatibility of the battery, and it enables you to purchase the correct replacement without guesswork.

Step 4: Decoding the Date Code

The most important information on the battery label is the four-digit date code. For example, a code might read "2138." This code is your window into the manufacturing history of the battery. The first two digits reveal the year of manufacture, while the last two digits tell you the week within that year. A battery with a date code of "2138" was produced in the 38th week of 2021.

Step 5: The Importance of the Manufacturing Date

Understanding the battery's manufacturing date is crucial. It's recommended to replace your two-way radio batteries every 18 to 24 months to ensure reliability. However, the date code indicates the manufacturing date, not an expiration or "best by" date. Batteries can be stored for several years without a drop in performance, provided they are kept at the correct temperature and charge level.

If your battery’s date code suggests it's a few years old, don't worry. This does not necessarily mean the battery’s performance will be diminished. It often takes 6 to 9 months for batteries to move from production to the end consumer. Proper storage conditions are key to maintaining a battery's health over time.

When to Seek Professional Advice

Understanding how to read your Motorola two-way radio battery is more than just a technical skill—it's an essential part of maintaining the reliability and efficiency of your communications equipment.
