Midland rechargeable battery packs won't recharge and vibrate

I purchased 2 sets of Midland rechargeable batteries with AC desktop and DC chargers Model BATT-5R Ni-MH for use in Midland 2 way radios Model GXT-550. These batteries accept and hold very little charge, even after leaving the radios on to deplete the batteries and then rechaging from an empty bank. They also vibrate when installed in the radios or when turning the radio on. Repeated removal of the batteries from the radios and replacement eventually caused the vibration to stop, but still won't hold a charge.

I've contemplated trying the DC charger but knowing something is wrong with the batteries (presumably, not the radios, since alkaline batteries show full power and don't vibrate) I'd rather just return the batteries/chargers for a refund. There is the possibility that the problem is with the desktop charger itself even though the charge lights are on when the radios are installed.

Are you aware of any reason why this would happen and more importantly is there a simple fix the consumer can employ, or do I need to return the charger/battery sets for credit? I hate to use alkaline/disposable batteries for environmental reasons and cost.

Thank you.

    Thanks themoneypit and eradiostore for your comments. I checked the Midland website FAQ and found the following comments regarding charging. If I'm reading this right, my batteries are fully charged even though only one bar shows on the battery indicator. They don't mention that with fresh AA's the battery icon shows 4 bars...

    I'll see how long the radios last just in standby with no transmit/receive use and should get more than 15 hours of power according to anothr FAQ response on their website. If so, I guess there may be nothing wrong...which would be the good news.

    Thank you both again.



    I’ve had my radios in the charger for three days but the battery icon only shows one bar when I turn it on.
    When the radio is turned on you will see the battery symbol along with all of the other items on the display, this is just a display test and has nothing to do with the charge in the battery. If the battery gets low you will see the battery icon continously flash.




    When I turn on my GMRS radio it always shows a Low Battery Icon. What gives?
    The icon on the radio is a low battery indicator only. It does not change to show a full or half charge. The low battery icon will come on the screen and continuously flash when the batteries are low.

Hello batterbum, from the info you listed you have the right battiers & charger, with alkaline the radios work leads to wrong or a bad batch of Ni-MH battiers. Vibrations from a battery pack states too much current being drawn for battery capacity. Note: depleting a battery and recharging with a charger will place the battery in a false full charge state. Recharging a depleted battery with a DC power supply with current limit can reboot the battery to a 90% cycle. I suggest returning battiers for correct replacements, if they are correct 'by the book' ask for the highest in mAhr specs. Please inform me of your outcome. Good Luck

    You have made progress in elmination. Return the battiers & charger for replacements of the largest mAhr (milliamp hour) that will physically fit in the radios. Before leaving the store have the sales person place them in the charger to confirm the correct icons light up, should display full or 90% charge. Before using the battiers complete an intial 16 to 24 hour charge.

You might contact Midland Radio Corp to see if they have a fix for your problem. If I had to give an educated guess I would say the batteries need jump started (which sometimes happens when they are new and too low of charge; or there is a problem where they contact the charger and they are not receiving a full charge; or they are defective. I am sure the factory would be happy to assist you in solving the issue.

How could i change its batteries?


  • Your radio, Midland LXT110, utilizes a NiMH rechargeable battery pack or 3AAA batteries. I have a similar set and when the battery pack runs out I just use regular AAA rechargeable batteries. They are more economical. To change the batteries in general follow these steps.
  1. Remove the back clip.
  2. Now remove the battery cover by pushing down from the top center of the battery cover and slide it off.
  3. Replace batteries observing polarity.
  4. Replace the battery cover.
  5. Replace battery clip.

Regards, Tony

How to charge battery in Motorola Talkabout Distance DPS


You can obtain a wall adapter style charger for your radio at your local Motorola dealer, or online at http://www.eradiostore.com/cart/index.php?target=products&mode=search&subcats=Y&type=extended&avail=Y&pshort=Y&pfull=Y&pname=Y&epcode=Y&q=htn8232

Sidenote: The rechargeable battery is good for about 2 to 3 years. You can tell the age of your battery by looking at the date code on the back of the battery above the stop sign. The first number is the year, the next two numbers are the week of the year. 915 would be 2009 the 15th week. (Or if very old it could be 1999 the 15th week.) A good battery, when charged will go an 8-10 hour day.

Keep both of your charge trays, replacements for these are no longer available.

Midland radio battery pack constant vibrate


Hello pjbracht, I just responed to a duplicate of your problem. If they are new, return the battiers and confirm they are "by the book" replacements. If so ask for replacemrnts with a higher mAhr. It is not correct for vibration from a battery pack, lead, NiCad, Ni-MH, period.

I'm assuming you're using the NiCd batteries. NiCd batteries do not last forever and need to be replaced when they show a resistance to beign charged. To optimize the life of these batteries you need to let them fully discharge before attempting to charge them. This is impractical most of the time.

You have two choices:
1. Purchase a NiMH charger and AA batteries and use that INSTEAD of the CHARGER STAND and NiCd batteries. This type of battery can be recharged without the problems discussed earlier and will last longer... or
2. Purchase another NiCd battery pack.

Low battery icon on Midland LXT350 walkie-talkies


Your LXT350 is equipped for using an optional rechargeable NiMH battery pack which can be recharged by inserting the AC adapter into the radio charge jack, or with the optional desktop charger.

I would make sure the radio is off, then insert the charger. Charge only for the prescribed time (no more/no less) and remove from the charger.

Charge time is initially 24 hours. Charge time is about 12 hours thereafter. For maximum battery life, it is recommend charging the battery pack when the low battery icon comes on. Remove the radios from the charger when the charge time expires.
