Question about Uniden GMR-1558 / 2CK 2-Way Radio

1 Answer

Short Battery Charge

I purchased two of these units in March 2008 with NI_MH batteries. I use them to maintain contact with my wife while operating equipment at some distance from the house. Battery dies after only about two hours of being in ready mode. Is this normal? Can I increase battery charge time by decreasing volume when in ready mode? Will I get better service with AAA batteries? NI-MH are very expensive.

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

Icom bc-179 do not charge the battery


Charging a battery requires two components. A working charger and a functioning battery. The concept is simple. A battery charger must output more voltage than the battery does, and at an acceptable current level. First determine the battery output from the ID sticker, then measure the charger output. It must be 1 or 2 volts more than the battery output. If the charger is working, charge the battery overnight. If the battery does not charge or runs down quickly, the battery must be replaced. All batteries have a limited number of charge cycles. The most common problem with Ni-Cad batteries happens when they are re-charged before they are completely discharged. Recharging a half used Ni-Cad sets up a short term memory and the battery discharges faster than normal.

STD-FNB-83 1400mAh NiMH Replacement Battery Pack for HX370S Handheld VHF Radio won't hold a charge


Hi Sarah,

Don't despair, there is a solution to this sticky problem, it will cost a little more, try the Lithium Ion version battery, these can be purchased online at ebay for a much more reasonable price than in some stores.

The make of your radio is the VERTEX Standard, is that correct?

If so, you'll have no problems finding your batteries under Electronics section on ebay.

I hope you find this solution helpful.

Kind regards,
Peter

Where can I get a new set of rechargable batteries for my cobra microtalk cxt275


The Cobra CXT275 radios can operate on any type of battery (Alkaline, Ni-Cad, NiHM). Each radio uses 4 AAA batteries. Only special rechargeable batteries can be recharged in the actual radio (see below)
If I remember correctly, they come from the factory with NiHM batteries rated at 300mAH. "mAH" stands for milli-Amphere-Hour and it represents the storage capacity of the battery. (The larger the mAH, the longer run time of the battery)

You have 2 options: A or B
Option A) Buy a set of Nickel-Metal Hydride AAA rechargeable batteries and a external battery charger. When the batteries die, pop them out of the radio, and charge them in the external charger. When they are recharged, pop them back in the radio.
Option B) If you want the ability to charge the batteries in the radio, using the "drop-in charger" then you will need modify the batteries so they can charge in the radio.
Follow these steps: You must be somewhat electrically inclined to do this...Note: By doing this you are going to void the warranty of the radio and new batteries that you just purchased.
1) Buy a set of Nickel-Metal Hydride AAA rechargeable batteries. You can probably find some rated at 600 mAH (this will extend the run time)
2) Looking at the back of the radio with the cover removed, there are 4 slots for batteries.
3) Looking at the battery slot on the far right, you should notice 2 contacts for the negative contact. The one on the bottom, is the contact for the radio to receive power from the battery. The one on the side (about 1/8" inch up from the bottom contact), is the contact for the charger to recharge the battery.
4) You will need to modify 1 battery for each radio. Somehow you need to bridge the bottom contact with the side recharge contact.
5) (look at the negative end of the cobra factory batteries and this should help you realize what you need to do) depending on the manufacturer of the new rechargeable batteries, you may be able to use an X-acto knife and remove 1/4" of the plastic wrapper from the bottom of the battery on the negative end. This should reveal the metal shell of the battery that can mate with the radio's side recharge contact.
If it does not, you need to find another way to have it mate with the bottom contact. You might be able to use some Aluminium Foil to bridge the bottom contact with the side recharge contact. Be sure the Aluminium Foil does not touch the positive contact of the battery to the left! You could have an electrical short!
6) Insert the Modified Battery into the right slot.
7) Insert the other 3 new batteries into the other slots. These do not have to be modified. Only the right most battery needs to be modified.
8) Drop the radio in the charger for the batteries to charge. The red LED on the charge base should come on. If it does not, then the side recharge contact is not making a good connection with the negative battery terminal.
9) If the red LED comes on, then the modification works. Let the batteries charge for 24 hours for their first initial charge.
10) When the batteries die after radio use, then charge them for about 12 - 16 hours in the drop-in charger. Do not let the radios sit in the charger for long periods of time. That can destroy the batteries. Take the radios out of the charger when the allotted time has passed.
11) If you hardly ever use your radios you will want to drop them in the charger for about 8 hours every 3 months. This will keep the batteries fresh without damaging them.
I hope this helps, Thomas (Electrical Engineer)

No, the charger is only usable to charge the rechargeable NiMH or Li-Ion battery which comes with the radio. Attempting to charge Alkaline rechargeable batteries with this charger could cause the to expode. If your charger is not charging the batteries which came with the units, it could be you do not have the charger cord end plugged in all the way, or the batteries dropped below the initial charge level by setting on a store shelf too long. Most TalkAbouts come with a cradle style charger to hold the radio, and a possible plug to plug into the charge hole. Check all connections, and clean any battery/charger contacts with a pencil eraser. To re-initialize the batteries you would need to attempt 3-5 charge cycles by charging for 8-10 hours, then letting the battery rest for 8-10 hours, repeating 3-5 times as needed. If this does not bring the battery back to life, you need to replace the batteries.

Midland rechargeable battery packs won't recharge and vibrate


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.

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.
