radio ran overIt happens more often than you might think… an employee comes in to tell the boss “someone ran over my radio”. The radio repair center sees them in all shapes and sizes (Motorola, Kenwood, Vertex and others). Some are repairable, while others are not.

What to do if your radio gets ran over:
1) Turn off the radio. Look for physical signs of damage.
2) Be especially watchful of any battery which has been squeezed or crushed. (See the previous blog post about this.) If the battery is obviously damaged get rid of it in hazardous waste. If you are uncertain, send it in with the radio.

The good news is many business grade radios survive being driven over by a loader or truck. All is not necessarily lost. If your radio is damaged get it in to the radio repair center right away. Let us know it has been squeezed or crushed. We will do what we can to get it repaired and back to you right away.








GOT STATIC? GOT POOR TRANSMIT? Using an old battery on your radio can cause you problems, including poor or intermittent transmit, a battery that no long last the full day, lots of static or white noise, poorly functioning add-on audio devices, and more. Continual use of an old or bad battery can eventually cause wear and tear to the radio itself, resulting in the need for repair. The life expectancy of the average rechargeable battery used in 2-way radios or other devices is 2 years. This includes your rechargeable flashlight as well as your portable radio.

How can you tell the age of your battery?
Nearly every manufacturer of a rechargeable battery marks the battery with a date code representing the date of manufacture. Sometimes these date codes are hidden in plain sight. You might feel like you need a secret decoder ring to break the code. Motorola is no different than most manufacturers, their batteries and accessories are marked with manufacturing codes.battdatecodes

Motorola batteries follow a very simple date code system. You will find a 3- or 4-digit number on the battery label (or embossed in the plastic of the battery itself). Use the example 1611, the first two digits are the year, and the next two digits are the week of the year. The battery shown is dated 2016 the 11th week.
If you have a 3-digit code the first number is the year. 611 would be either 2016 or 2006. (You can usually tell by the appearance of the battery if it is 10 years or more old.)
For more details see this PDF: Battery Date Code Sheet

Next time you have a poorly functioning radio check your battery date code. Maybe you simply need to replace your battery.

Battery tips:

  • Clean your battery contacts on your radio and charger periodically with a pencil eraser to remove any film or debris. This will allow your radio to make better contact on the charger. (Never use chemicals or a sharp object to clean contacts.)
  • Always have your radio turned off when placed on the charger, and if in an emergency you must have a radio turned on when on the charger, never ever transmit while charging. This can burn out components in your radio causing the need for repair.
  • If you feel you have an old, bad, or poorly functioning battery, try trading batteries with a known good radio and see if the problem is solved. You may simply need to replace your old battery.
  • The shelf life of a battery which has never been charged (initialized) is supposed to be indefinite. If you store new batteries before you use them, mark them with the date you initially charged the battery. This will give you a better idea on your 2 year life expectancy.
  • When initially charging a battery that has been in the cold or stored for a period of time before use it may take 2-3 charge cycles for the battery to successfully take that first charge. If you charger is blinking when it usually doesn’t, leave the battery on the charger and let it blink a few hours, even try again the next day doing the same thing. The battery will usually wake up, charge and be fine.
  • Beware of aftermarket batteries from less than reputable sources. We’ve seen or tried them all. We do offer a good aftermarket battery for most models if you are looking for such a battery.
  • Dispose of all old batteries in hazardous waste.

cellphone vs radioWe often are asked by friends, family and clients about the status of 2-way radio in a world where everyone seems to be carrying their own personal communications device, a cell phone. Here are some of our thoughts and thoughts of those in this industry concerning this subject.

Most people would admit they could not function without their smart phone, the computer attached to your hip. But in reality, as a communications device, a cell phone is still a device for making a phone call to another person. You dial a number, let it ring, wait for an answer, hope to talk to the person you are calling, possibly leaving a voice message. The process takes at least a minute of your time or more just to connect. And following this routine, you may end up having a conversation for several minutes.

When using a two-way radio you simply press the push-to-talk (PTT) button and instantly speak to your group (or one-to-one depending on your radio system). You can give a brief message or instruction, receive an immediate response and finish your task accordingly. The entire process typically takes a few seconds. It is fast and efficient, saving time and money. In the realm of public safety and businesses such as construction, it can save lives. In addition, radios are highly effective in high noise environments, built rugged for long-term use, offer an intuitive one-touch user interface, and feature a battery designed to do a full day’s work.

Nearly all business models of two-way radios are repairable and have replacement battery packs available. The life expectancy of a two-way radios is up to 10 years, with many exceeding this mark.  Computing the cost of purchasing a typical business 2-way radio (Motorola CP200) over 10 years including replacement batteries every two years and 1-2 repairs, it would calculate to under $10/month to own/operate the radio. Much less than the overall cost of cellular for the same time period.

Cellular devices are generally speaking rather fragile. The majority are too lightweight for work environments. Battery packs are often non-replaceable.  If you talk to those in the cellular industry, you will find the life expectancy of a phone is about two years. At the 2-year mark, the cell carriers are ready to make a deal with you where you can get the next model “free” or inexpensively to keep you as a client. The industry is reliant upon the monthly fees we all pay. We’ll let you do the math on what a maintaining a cell phone will cost you over the course of 10 years.

Radio communication is instantaneous with the simple use of a PTT button. The person needing information  receives it quickly. Requests for assistance are heard by everyone monitoring the frequency. This is essential in many industries and especially in public safety. Radios designed for public safety can also have other features such as an emergency button or a mandown feature where the radio will notify dispatch of an officer who is no longer vertical. In construction when giving instructions to a crane operator PTT radio technology is the quickest form of communication.  Think about restaurant hostesses or retail clerks communicating with others on their team. This type of communication is done more efficiently using a radio versus a cell phone. It would be hard to imagine the public safety or business world without 2-way radios.

Cellphone & CP200 side-by-sideAnd up to now we haven’t mentioned the downside of using a cellular device instead of a radio, things such as surfing the web, playing games, making personal calls, just aren’t a problem when businesses use two-way radios for their onsite communications. So when choosing between using your smart phone and 2-way radios, you can see where the two devices differ both in features and overall long term cost. Both have their place where they can work to the best advantage. It’s up to you as a business person to choose your communications device wisely. ~cl

Boxes and boxes of new replacement batteries, we are surrounded!

We are sharing the savings with our customers.  Bulk Purchase batteries are available in 2-packs, 4-packs, and 8-packs. We’ve posted the popular battery models’ 4-pack pricing on www.eradiostore.com. If your battery isn’t listed just give us a call and we can give you pricing.

Just a reminder, be certain to dispose of any old batteries properly. These are considered hazardous and should not go in landfills. You can find your nearest battery recycling center by visiting http://www.call2recycle.org/locator/ Any radios sent for repair with bad batteries can have their batteries disposed of at the repair facility at no charge.  Just let us know and we’ll be happy to help by putting them in our recycling bin.


NNTN4497The Motorola CP200 radio has come with 3 different battery types over the past few years. The current CP200, CP200-XLS, and new digital CP200d come with the NNTN4497 Li-Ion 2250 mAH battery. You can expect this battery to give you a good full work day of 12-14 hours. Life expectancy is approx. 18-24 months. Li-Ion is less likely to suffer from the memory effect which is common to the NiCd chemistry of batteries. It is the preference battery by most users.


The trickle (slow rate) charger is only useful for charging one chemistry of battery, the NiCd NNTN4496. Early models of the CP200 radio came with the NiCd battery and a trickle charger. Note: The NNTN4496 NiCd battery is no longer available from Motorola, but still available from after-market vendors. Older model CP200 radios can be upgraded to use the current Li-Ion NNTN4497 battery and a fast rate charger with no modification needed to the radio. You would simply need to purchase the Li-Ion battery and a fast rate charger.

The next step up in radios from the CP200 is a nearly identical PR400 radio. The PR400 radio can also use the same chargers/batteries as the CP200 line of radios. The PR400 comes standard with a slim Li-Ion 1600 mAH battery NNTN4970, which will also fit the CP200 radio.

The single unit and multi-unit fast rate drop-in chargers for the CP200/PR400 radios will accommodate any of the above mentioned battery types. The charger features a convenient insert which can be removed and turned around to fit the size of battery being used. This same insert has vertical rails which guide the battery into place, and will hold a battery alone or a battery attached to a radio in place during charging.


Most batteries will last approx. 2 years (or 3 years if you treat them really well). Use the manufacturers date code to determine the age of your battery. On a Motorola brand battery the first digit(s) are the year and the last two digits are the week of the year.  Example: 1226 would be 2012, the 26th week, and 226 would also be the same date (or if very old it could be 2002, the 26th week). Keep in mind using an old battery for an extended period of time can eventually lead to the radio needing repair. If you plan to use your radios for many years it is wise to replace your batteries every 2-3 years. This will help keep your radio in tip top shape.As always, call us if you have questions.

Radio battery life expectancy is a common topic of conversation among radio users. As a general rule rechargeable batteries last between 18-24 months, with some variation for chemistry types, with NiCd and NiMH batteries at 18-24 months and Li-Ion 14-18 months. These are approximate numbers. If you treat your battery well, and do not overcharge it, undercharge it, or  otherwise treat it poorly, you may get as much as 3 years from the average battery.

Signs of a bad, defective, or aged battery include constant or intermittent static, a shorter work day, and intermittent or poor transmit. Transmit problems are an early indicator of a old or bad battery. It is simple, it takes more energy to transmit than to receive. So if you have a radio that receives perfectly, but is iffy on transmit, check your battery.

So then the question arises… What happens if I continue to use the old battery? Just like any home appliance operating on low voltage, your radio will eventually have failures associated with the brown out. Then the simple need for a replacement battery turns into a battery + radio repair. As you can see, it would be much cheaper and wiser to replace the old battery when needed.

How do you know the age of a battery? On Motorola brand batteries you will find either a 3-digit code or 4-digit code on the label of the battery or embossed in the plastic of the battery itself.  (See above photo for an example.) The first number on the 3-digit code represent the year of manufacture, the next two numbers are the week of the year. Example: 226 would be 2012 (or heaven-forbid 2002) the 26th week of the year. The newer 4-digit date codes are easier, 1226 would be 2012, the 26th week.  If you have difficulty determining the age of a battery, give us a call and we’ll assist you. 800-872-2627.
