    Tried new batteries, used litium ion batteries instead of nimh, didnt help, have contacted place of purchase and garmin very upset as i purchased 2 units!

    Have exactly the same problem & tried the same fix re changing battery types. Unit gents very hot and new batteries are exhausted within one hour when unit is off.

    My two 110's have same problem.

    With two new sets of different brand NiMh rechargeables the problem still exists.

    Both units get warm and flatten the batteries within 3 hours with them turned off.

    same issue here.  I opened the device up, however, and a certain part of the board seems to be incredibly hot, even when the device is off.  Still trying to figure out what part is hot, however, because it's located on the bottom part of the board that doesn't seem to be accessible.

    Same problem and no the batteries worked fine in my other rino 110

  • ismaelj Feb 09, 2009

    Hi I have 2 of these Rino with exact same problem. Can anyone say if they have had them fixed and if so what was the problem. I am in Australia and they are not sold or repaired here. I have looked at them but because both are the same and the SMD markings on the IC's seem to be unavailable I have no way of checking for the fault. Any help would be appreciated as the units are unusable at the moment. Please email me at if you have a solution or a circuit diagram:)
    Regards Ismael

  • ismaelj Feb 09, 2009

    I have the same problem on 2 units. I have tried to fix but no circuit diagram and the SMD Marking code is I think Garmin's own. If anyone had this fixed and can give me the information would be great! OR a circuit diagram for the units. Hard to track down as both units are the same and being in Australia we don't have Rino's here so Garmin Australia don't want to know. If you prefer to contact me direct my email is

    Regards Ismael

Ok first maybe you have defective battery, the battery is now in leak condition! or maybe you have to clean the terminal of the battery!

Camrea drains batteries quickly?

Rechargeable batteries do wear out, and don't hold charge as well. It's about time to get some new batteries.

Radio shack walkie talkie 21-1914 replaced batteries will not charge

Hi pearl,

A simple problem to solve at last!!!

Inside the battery compartment you should find a switch, which indicates Recharge/Normal, make sure you select recharge if your using these batteries, otherwise no charging occurs.

If this does not work, take out the recharchables and select normal on switch, place fully charged normal batteries into the compartment, making sure you put them in the right way around, close the flap and turn on the radio, if this works, then your battery switch is faulty, however, you can get lithium ion batteries, which will last longer than most other high duty batteries.

The cost of getting these radios is not worth the money, unless you are technically minded and buy the repacement switch and repair it yourself.

Otherwise try all of the above, and remember, when charging batteries that are rechargeable, never leave the radio on, as this can wear out your batteries quickly.

I hope this advice is helpful to you.

Best regards,

I bought 6 sets of Midland LXT 345 walkie-talkies for the teachers to use when they go out on the playground. Less than 1 year later several of them don't work. They keep them in their charges when...

The batteries have likely been damaged from being on the chargers too long. Try trading a known good battery into the non-working radios and see if it/they will work with a good battery. If so, replace your batteries, and then only put the radios on the charge when they need a charge, such as after the radios have been used 8-10 hours. Longterm charging can quickly age batteries. Life expectancy of a battery is 18-24 months with good care.

Best regards.

Batteries don't last but 2 or 3 hours after taking 20 to 25 pictures on 2 gig card batteries are gone.

What kind of batteries are you using? what is the milliamp rating on the batteries? Are they still the stock sanyo batteries? If you are using flash and the screen it can wear out batteries pretty quick specially if they have been recharged alot of times. If they are not new then you probably need to invest in a new pair of rechargeable batteries. If they are new batteries check to see if the MAH rating on the bat tery is higher or lower then the old ones. If you want to buy new ones click here
Let me know from there and i can assist you further. Thanks, Midwest-tek

What's the quickest way to drain the battery?

Simply leave the radio turned on overnight. Most TalkAbout radios have a 12-18 hour battery life. Pressing the PTT button can also speed the process but is not recommended, as it would cause wear and tear on the radio, and possibly shorten the life expectancy.

FYI: The rechargeable batteries with the TalkAbout radios typically do not need discharged before recharging, as they are either NiMH or Li-Ion and have very little memory effect.

Best regards.

Batteries die quickly - unit gets hot

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.

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.

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.
