How to Read the Date Code on your Motorola Two-way Radio Battery

Do you ever wonder if the problems you are having with your two-way radio is due to the battery? One important thing to know about the battery is that it has a date code located on it! Depending on use, Lithium Ion batteries can last for 3-5 years. It is important to know that radio problems you are experiencing may just be because you have an old battery on your radio that needs to be replaced. Lets look at the picture below:

Next to the part number of the battery (NNTN4497CR in this case) there is typically a 4 digit date code. For example, on this battery we see the code “1512”. The first two digits have to do with the year of production. So with this battery the “15” stands for 2015. The next two digits stand for the week of the year that the battery was manufactured. This battery was manufactured in the 12th week of the year.

So, from reading the date code, we can see this battery was manufactured on the 12th week of 2015.

In some cases, if your battery is very old, you will see only 3 digits. For example, the code “145” would stand for the 45th week of 2001.

Make sure your battery is up to date!

Noise-cancelling accessories are available for radio users that need to be able to communicate in loud and noisy environments.

In addition to earpiece and headset accessories, multi-unit chargers can help you charge all of your radios in one place and can help your staff easily keep track of where their radios are when charging.

Many radio users may need to carry extra batteries with them while in the field or on a job site.

Tips to Improve Battery Life For Your Two-way Radios


Here are a few tips to help protect your rechargeable batteries and increase their use and performance life. Taking proper care of your rechargeable batteries can save you and your business money in the long-run!

1.Charge your new battery overnight before using it. By charging your battery overnight for the first time, this INITIALIZES it.

2.When using a Motorola Rapid Charger, leave the battery in the charger for an extra 1 to 2 hours after you see a green light. This applies to non-IMPRES batteries only.

3.DO NOT leave your fully charged radio and battery in the charger when not charging. This will eventually shorten battery life.

4.Stabilize batteries to room temperature when charging. If batteries are charged in extremely cold or extremely warm temperatures performance life of the battery will decrease.

5.Only charge a battery when it needs it. If it is not fully discharged, do not recharge it. We suggest carrying a spare with you if need be. This is the most cost-effective solution for users requiring a longer operating time with their radios.
