Question about Garmin Rino 120 2-Way Radio

Batteries die quickly - unit gets hot

My Rhino 120 dies after about 1/2 hour, fully drains the batteries(I can watch the batteries indicator drain before my eyes). The unit also warms up and the display and surrounding areas get pretty warm. Never in or near water, no impact damage. What is the problem?

    I have a rino 120 that I have had for about two years and it gets very hot after about 5 minutes with new batteries in it. I have tried both alkaline and rechargegable batteries and they both do the same thing - gets very hot. I have also plugged it into my cigarette lighter adapter - no batteries and it still gets hot. I put in new batteries and left the unit OFF and it still got hot. I own 4 of these and only have the problem with the one unit. I have tried to update the os, but it doesn't help either. Does anyone have a solution other than sending it back to Garmin?
    Thanks

    I have the same problems with my 120. I have a 130 and it works fine. I saw another unit on craigslist that listed the same problems. Has garmin done a recall?

You may have a bad or shorted battery pack. You might try replacing it to see if the problem goes away. It would be normal, while charging for a battery to get warm. But not hot. Rechargeable batteries have a life expectancy of 18-24 months.

    Check your battery contacts to see if there is a break in the solder which connects them to the board. Something is shorted, if it is not the contacts, it is in the component board itself. This could be from a variety of causes, including pressure against the unit, such as being simply sat on, causing a hairline crack in the board. If this does not reveal the problem, contact Garmin.

Every time I press the talk button the radios show low battery icon and I'm not able to transmit on either radio. How can I rectify this problem?


Hi,

Are you SURE that your batteries are up to snuff? I.E. when they have a light current load on them they are ok but as soon as you try to increase that current load they die off quickly. With two-way radios, the actual current drain depends on whether you are transmitting or in standby (receive) mode. Transmitting requires significantly more current than standby mode. So, I would look at what kind of batteries you are using. If they are a good name brand alkaline, check to see if they measure close to 1.5 volts with a voltmeter or check them with a battery tester to ensure they are good. If they are ni-cad or ni-mh rechargeable batteries, make sure they are rated at least 1200 mah (milliamp hour). I use Sanyo eneloop rechargeable batteries. They last a long time for me. One other thing, make sure your battery compartment is clean and there is no corrosion on the contacts the batteries are placed into.

Hope this helps,
Jim

Walkie talkie batteries don't last


The Batteries that Motorola uses will die after a while mainly because people leave them on the charger all of the time. But there is a way to refresh them. You let the battery die completely, then you charge it up for about 12 hours. Then you let the battery die completely. Do this a couple of times and the batteries will last long.
Also, Motorola use to make a battery refresher (or did when I worked there.) It will charge and drain the battery automatically. It will even give you a fault if the battery is completely dead. For the HT1000 (for example) it would be the WPPN4065BR.
For future reference, don't constantly charge a battery. Only have it on the charger when the battery is actually dead or very low. This will increase battery life.

Batteries drain in and hour


You have a short circuit in your radio. Our Motorola's do this occasionally We can't fix them in house, the defective part is a surface mount device, we send them back to the factory where they replace the entire mother board.

Short Battery Charge


Hello Dave2794875,

According to manufacturer specifications the NiMH rechargeable batteries should provide about 12 hours of operating time assuming a 90/5/5 operating cycle (90% standby, 5% receive, and 5% transmit). Theoretically, decreasing the volume can help somewhat but should have a minimal effect.

If you are only seeing two hours of standby time then you are definitely not getting the specified amount of time. This could be indicative of a problem with the charger or the battery pack or both.

Using disposable alkaline AAA batteries, you should see an increase in operating time because alkaline batteries have more capacity and last longer then rechargeable batteries. However, if yu do a lot of operating the cost of disposable AAAs can add up fast. For most users the rechargeable batteries are much less expensive in the long run. If you only use the radio occasionally then alkaline batteries are the way to go.

Hope this helps,
Ken

Overheat/battery drain


Hello dogwillhunt,

It is normal for a two-way radio to generate some heat, especially during extended periods of long talk time. Consumer two-way radios tend to be much more susceptible to this because they tend to be constructed out of materials that do not dissipate heat very efficiently, such as polycarbonate and plastic. Periods of heavy transmit times also use additional power, causing the radio’s batteries to run down more quickly and require replacement or recharge. Use of the display backlight feature can generate additional heat and run the unit out of battery power even more quickly.

If the radio is heating up excessively and burning through batteries (pardon the pun) in situations where you are not using the LCD backlight excessively or transmitting for long periods of time, this may be indicative of a problem with the unit that would require service, such as a short or defective component. If such is the case, I would recommend contacting the manufacturer.

Yaesu FT-50R battery drain


scotwho, I personally do not know the radio you are asking about, but I do have many years working with radios in troubleshooting. What I am guessing is, if the heatsink gets hot, then whatever is connected to the heatsink has shorted out. Two main parts come to mind here, and that's the audio chip, and the transmitter output final/chip. Possibly the main IC (brain) that controls most everything, but I doubt that. The radio needs to go to a repair shop that can troubleshoot the damage/ and find an answer as to why it occurred. A lot of times the factory's do not use heatsink compound when they assemble the units, and after an x amount of time the part/parts will fail. 10cents worth of heatsink compound can make a radio last a few years longer.
Probably not the answer you wanted but I hope this helps,, let us know. Mechanic

Batteries in my Rino 120 don't last very long


I believe its 3AA's and it SHOULD last 15 hrs of life. You should probably check the terminal heads and clean them real good you might be shorting somewhere in the connection.
