Cobra PR3850WX will not recharge batteries

I have a pair of Cobra PR3850WX handhelds that will not recharge batteries when placed in charger, nor will the led on charger light up. Checked charger with volt meter and it showed 12v, also placed a discharged 9v battery across charger contacts, the led light came on and battery showed a gain in charge from 2v to 7v in about 2 min. Can you help?

Thanks,
Dave

There is a contact in the upper left hand corner of the batt compartment.This has to touch the metal of the last batt.If your batts have paper around them scrape it off where it contacts that contact point.

I have had this issue before. The contacts on your radio may not making sufficient contact. I would clean them thoroughly, maybe rub them with something abrasive (fine sand paper) Is there any measurable charge in the battery's?

Charge time cobra 235 recharge batteries


Hi! I've got a different cobra model and I find it ridiculous, but there is no indication when the batteries are fully charged... Either use external charger for your batteries or just leave it plugged in overnight- that would ensure full charge (it does in my case, I've checked batteries with multimeter)

Cobra microtalk will not charge


this is the sign of a damaged or dead battery pack. they can be rebuilt at Batteries Plus or replaced. I would also try alkaline batteries in the radio before spending money on new battery packs. Most rechargeable battery packs must be kept charged regularly, and should be fully discharged before recharging, or they will be damaged and end up with a limited lifespan. IF you are handy with a multimeter you can check to see that the charger is putting voltage out by placing the probes on the contacts while it is plugged in. especially if the cord is twisted or looks stretched, but generally it is the battery not the charger.

Cobra Micro Talk PR4750WX.New rechargable batteries will not charge in provided charging cradle.


The original Sanik batteries have a negative side with about ten mm of metal showing on the side. Trim the plastic off your new batteries to match and the cradle charges again.

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)

I have an Energizer Model CHDC7 battery charger for AA/AAA batteries. I'm not sure how to use it. Specifically, when batteries are inserted and plugged in, it displays flashing green lights over all...


Nickel-Metal Hydride (NiMH) batteries are usually charged in pairs in consumer chargers. The CHDC7 can charge two or four batteries at a time. Their position in the charger is important (see the link at the end of this note). Each battery has a separate pair of green LEDs. There are no other LEDs on this charger. The LEDs light up to show the state of charge. Flashing means it is charging. Solid means it has reached that level of charge (ie, 1 LED = half charged, 2 LEDs = fully charged). The batteries will get warm but not uncomfortably so. After some practice you will be able to tell if they are getting too hot (which may signal a worn-out battery which should then be replaced). Like all rechargeable batteries, NiMH batteries have a finite life (measured in number of times they've been discharged and recharged). IMHO, they should also be used and charged in matched pairs. I mark them when I take them out of the box and keep them paired in use and in charging for maximum life. Yes, the devices that use 3 batteries are a pain to deal with. LOL. All details can be found on this Energiser data sheet: http://data.energizer.com/PDFs/chdc7_instructions_english.pdf

P.S. The CHDC7 remains open for charging. Closing it for storage is optional but minimizes the space it takes up.

Constant RX mode on cobra microtalk PR3850WX


Sounds like the radio was subjected to electrostatic discharge. If you have your manual, and it describes a way to do a "master reset" on the radio, follow the instructions. This usually involves pushing down on one key while turning the radio on. Otherwise you have to find a licensed dealer for factory service, as there is no way to repair the radio yourself. The use of surface mount technology still confuses many Techs unless they have been to a company's two or three week seminars.

Cobra HH 40 charger specs


I have a Cobra HH-40 CB radio and am charging it as I type. The included charger is rated at 16V DC, 100mA. The pattery pack charges 10 AA rechargable batteries (the manual specifies NiCd, but you can also safely use NiHM). The 12V DC car charger included cannot be used to charge the battery pack, but can power the radio.

Microtalks won't charge


I have the Cobra Microtalk 4100 FRS radios with charging base. After changing the batteries with new nimh rechargables the charge light would not illuminate and the unit would not charge. I noticed the original batteries had a metal band around one end. This band makes a small connection inside the battery compartment on the first battery. Seems to be a cheap way to ensure you dont try to recharge the unit with non-rechargable batteries installed. I rapped a small piece of tinfoil around one end of the first battery in the new set then popped it back in and now they will charge correctly again. Dont try this with non-rechargable batteries! I would recomend buying original replacement batteries.
