Check the Date Codes of Your 2-Way Radio Batteries

Magnum Electronics Supplies Batteries for All 2-Way Radio Models

It is that time again to check your radio batteries so you keep your communications loud and clear. Batteries begin to degrade after 18-24 months of use and can affect radio performance. Many intermittent radio problems are solved with a fresh battery.

How to Read a Motorola Battery Date Code

All Motorola batteries have a 3 digit date code on the battery label. Check the date codeMotorola Battery Label and Date Code Circled on your Motorola battery and if the first digit is a “0” or “9” it is a good time to replace it.

The first digit represents the “Year” and the next digits are the “Week” manufactured. For example; 036 is the 36th week of 2010.

All Motorola batteries carry a replacement warranty of at least a year after the date code and probably longer if marked IMPRES or contain NiCD cells.

Replacement Batteries for Motorola, Vertex, & Other Radio Manufacturers

We carry Motorola Original OEM, Vertex-Standard OEM, and Power Products batteries for all current and discontinued radio models.

Below are links to the most popular and recommended batteries:

We also carry replacement batteries for Harris, Kenwood, Icom, Tait, and many other hard to find models. Check our 2-Way Battery selection or call us and we will be happy to help you find the best battery for your needs.

Battery Technology – Lithium Ion vs. Lithium Polymer

2-Way Radio Batteries What is different between Li-ion and Li-Polymer Batteries?

We have received several inquiries about the newest battery technology, Li-Po, that is now available for 2-way radios. Historically, NiMH was an improvement as compared to NiCD and Li-ion has many advantages over NiMH. The assumption that Li-Po is now the best battery for your radio is more marketing than anything else.

Li-Po or Lithium Polymer battery cells still use the same chemical material as Li-ion but the difference is the way they are packaged. Li-ion batteries use a thick-walled, rigid aluminum case for the cells and Li-Po utilizes a new thinner foil aluminum case. Bottom line is the difference is all in the cell construction.

Both Li-ion and Li-Po are Recommended But Check the Specs

Li-Po battery manufactures must add a more rugged case to meet the mission-critical specs required for two-way radio specifications. When comparing Li-ion and Li-Po batteries the following should be considered:

  • Battery capacity measured in mAh – The higher the mAh number the longer your battery will work before needing a recharge. When comparing specs be careful when you see the words “typical” or “average” and not “minimum” or “rated”. Our experience is there can be a big difference in actual results.
  • IMPRES or Advanced Charging Technology – “Smart battery” automatic conditioning improves performance and keeps them in service longer.
  • Drop Specification – Dropping the radio is probably the most common reason why batteries fail. Most Motorola mission-critical batteries are rated at 36 drops from 5 feet to a concrete floor.
  • IP (Ingress Protection) Rating – Higher IP numbers are better and signify the ruggedness of the battery. The first number references solids and the second number signifies liquid protection. The highest solid number is “6” (dust tight) and the highest liquid is “8” (submersibility beyond 1 meter).
  • Overvoltage protection circuit – Better batteries have 2 levels, some have 1, and lower cost batteries may not include have protection at all.
  • Temperature Range – Extreme cold affects Lithium battery performance and the spec should be investigated if your environment is outside “normal”.
  • Intrinsically-Safe Rating – FM Approval is important if you use your radio in hazardous, combustible atmospheres where an electrical spark could cause an explosion.
