Two-way radio has become a commonly used equipment to have effective and quick communication on various job sites. Most businesses have recognized the functionality and usefulness of these communicators. There are several situations where nothing could come as handy as a two-way radio. For all of these reasons and more, these radios have become very convenient for many industries.

However, your two-way radio will only function as long as its battery is powered up. Therefore it is important that you get the quality of your radio and performing two-way radio batteries.

Whether it is for replying to the emergency call or bring together the team or for sharing important data with the workforce, two-way radios should always stay recharged to avoid any problems. Batteries are an integral part of any portable electronic gadget, they should be kept clean and healthy to get the best service. To give you a better insight into the battery-life, let’s start with knowing different two-way radio battery types:

Types of Batteries for Two-Way Radio

Primary & Secondary

Some of the portable two-way radio models use primary and secondary battery types. Primary batteries cannot be recharged; their life is generally for only one chemical reaction use.  

On the other hand secondary batteries can be reused after recharging. They have a slightly different chemical composition and reaction; they can be recharged and used multiple times. Batteries made from Nickel Metal Hydride or NiCad fall under this category.  

3 rechargeable battery types are used to operate two-way radios.

  1. Nickel Cadmium
  2. Nickel Metal Hydride
  3. Lithium-Ion
  • Nickel Cadmium Batteries (NiCd)

In this battery type, there are 2 plates on each cell- one is made with Cadmium and the other is made from Nickel. These metals enable users to recharge and reuse the batteries.

  • Nickel Metal Hydride Batteries (NiMH)

These secondary batteries can be counted in one of the recent discoveries in the technical-field. Almost similar to NiCad's, it provides approximately the same voltage as well. This battery type is best to have longer charge durations, but they do not have a long lifespan.

What is the average use-time and lifespan of a Two-way Radio Battery?

Normally, Two-Way Radios are shipped with rechargeable batteries. The users can recharge them and use them over and over for a period of time. However, various external and internal factors affect battery life. But on average, these batteries can live up from 18 to 24 months.

If you take proper care of your two-way radio batteries, then you might be able to get the battery performance to its best. Also, based on how heavy usage you have, these batteries can outlive 2 years lifespan.

If you feel that your battery asks for frequent charging or replacement, then you might find the below-listed tips and battery maintenance hacks very helpful.

Why does a rechargeable battery lose its charge very quickly?

The performance of a battery is based on its chemical reaction power; it generates voltage from the reaction. Hence, the battery life also depends on the soundness and cohesion of the surfaces that create a reaction. If the battery care is neglected in any way, the outer shell and materials will start to lose their power and battery characteristics will change.

This will end up in dropped recharging duration and exhausted battery. If you and your team regularly use two-way radios, then encourage them to adhere to the battery care procedure.

Making Battery Maintenance Easy for You

Having a 100% charge on your batteries is like a mood-uplift every morning when you step-up for work. And there are many tips to make this easier for you. Few two-way radios come with a battery and its charger; this would be a cost-saver deal for you. Also, if you have a large team working in the field, then this package will assist them out regularly.

Another thing to keep in mind about rechargeable batteries is that you must bring the battery down to the room temperature before keeping it for a charge. For instance, if the users work in freezing conditions or miners underground must follow this advice; too hot or too cold battery temperature while charging can affect its life.

On the other hand, leaving the batteries on charge for too long can also deplete the performance ability and battery life. Therefore, always remember that you have to remove the radio or the battery from its charging slot after the charging is complete.

Never forget switching of the charging point and removing the battery from the charger; it is very important. You can go for an overnight charging method to ensure the best results; it will also help in stabilizing the battery performance.

It is also important that you use the original chargers for battery charging. If you use any other charger it can cause severe damage, to the battery or you.

Li-Ion Two-Way Radio Batteries

Li-ion batteries are one of the most commonly used replacement batteries used in two-way radios. Here is a complete guide to Li-ion Two-Way Radio Batteries:

Charging Process:

  • Always charge the fresh batteries to 100% before using them for the first time. No batteries are delivered with charge in them.
  • If not mentioned on the charger, remember to switch off the radio before putting it on charge
  • Charge the batteries from the original only, do not use copies or other brand chargers.

Storage Habits:

  • Remove the battery from charge once it is fully charged. Overcharging will reduce battery life
  • When left unchecked, remove the batteries from their chargers. Continue with charging later.
  • Use the batteries for 5 years or less. After this, the battery composition starts getting unstable; it is not safe for use.
  • Dispose of or recycle the batteries properly.

Stay Away from:

  • Never use a battery that overheats while usage or is damaged physically.
  • Avoid using the batteries when they are below or above radio operating temperatures
  • Any conductor, like water, should be kept away from the batteries. It can cause a short circuit, resulting in flame and smoke.
  • Do not use a battery after it gets exhausted and dispose of appropriately.

Disposing and Recycling:

Ensure that the batteries you throw away reach proper recycling centers or are disposed of under proper conditions. Wrong disposal & use can be injurious for the health and wellbeing of people handling them.
