Is Your Motorola Two-Way Radio Battery Still Under Warranty? (How to find the date code)

Are your radios not working as well anymore? Do you find the range of your radios has been reduced, that certain radios are dropping transmissions, or that batteries are not lasting a full shift? It may be that one or more of your radios have a bad battery that needs to be replaced.

Battery Rated Capacity

A battery is still considered good as long as it maintains 80% of it's rated capacity or above and is typically good for around 3 years. After that they should be replaced because the battery capacity will drop over time. Once a battery drops below 80% of it's rated capacity it should be replaced. This is because the transmit power of a radio is based on the battery voltage and once the capacity is below 80%, the range of the radio will be reduced thereby compromising the radio’s ability to communicate reliably.

Using IMPRES Technology to find your Battery's Rated Capacity

IMPRES batteries contain a chip that records the battery's usage history. If you have an IMPRES battery, you can check the capacity of the battery with a Motorola Solutions Multi-Unit IMPRES Charger that has a display on it, or with an IMPRES Data Battery Reader. The important thing to note is that even if your battery is fully charged and the indicator light on the charger turns green, it is only charged to the maximum of it's rated capacity. This means that if the battery only has 85% rated capacity, it is has fully charged up to 85% of it's rated capacity. Usually, an IMPRES charger will flash red and green if the rated capacity drops too low.

If you have a non-IMPRES or 'Standard' Motorola Solutions radio battery, the rated capacity cannot be read using end-user equipment. Nevertheless, our service shop can test your batteries using our specialized in-house CADEX battery testing equipment. If you would like help testing your batteries, please contact us.

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

If you want to find out if your battery is still under warranty, you can check the age of a battery by looking at it's date code. The 4-digit date code is printed on the sticker at the back of the battery. See the example below with the date code circled in red.

Motorola Solutions Battery Date Code (circled in red)

The first two digits indicate the year (18 for 2018, 19 for 2019 etc.) and the last two digits indicate the week. In the above example you can see where to find the date code. In this case, the battery manufacturer date is marked from the 13th week of 2020.
