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.

    Thanks man. That really worked. I thought the base unit was gone because the leds were not working. I trimmed the plastic off to match the Sanik batteries and low and behold everything works. I cleaned the glue off the exposed side steel with NUTZLUBE to ensure good contact and not harm the plastic. Now the leds work and the radios are charging

The original 1200ma batteries have a different internal resistance. I had this problem with 2650ma Duracells. Use a external charger for these. The Cobra Charging station is useless with aftermarket premium batteries.

SOURCE: Batteries won't charge on new cobra 2VP 270 radios

If radios are brand new then I would take them back to the store for warranty exchange. The other opton is to vist a local radio service center and ask the tech to jump the battery. if the battery falls below a certain voltage it might need a quick jump sart from a power supply with a higher voltage normally 12 volts works well...

  • The fact that these turn on while on the charger is an indicator that the batteries are just that far gone. Depending on how much you like these radios vrs the cost of a new set is something to think about.

  • This link is where you can get a reliable battery replacement.

  • I use a newer Midland talk around for camping, hiking etc. The thing I always look for in a talk around radio is if the manufacturer battery goes bad or runs dry can I use some batteries at home with it? I like the fact I can put 4AA batteries of the shelf in my radio in an emergency. And when the stock battery gores kaput, I can use some AA rechargeable batteries I already have at home and save on replacing the battery or radio. Something to think about should you decide to get a different radio set.

Check your battery contacts to see if they have a film of dirt or debris. If so, clean them with a pencil eraser. Check to see they are making good alignment with the contacts in the charger. If these suggestions do not solve your issue, you may have a bad solder on a battery contact in the radio. (Be certain the radio is shut off when charging.)

Best regards.

Cobra pr 3850wx bought new NiMh 800mAh 1.2v rechargable batteries now the base charger lights won't come on when i put the radios in it


  • A Cobra 3850wx Radio requires 4x600mAh NiMH 1.2V AAA Part # GA-3ANH rechargeable batteries.
  • Not just any AAA rechargeable battery will charge in the unit.
  • All will work in the radio but not all will charge inside the radio. It has to be a specific battery.
  • This is an example of what you need. GA-3ANH batteries which will charge inside your radio. http://www.tomsawyer2wayradios.com/catalog/item/3823249/5076887.htm

they charge better if they are turned off. since they do not have a paid dedicated channel, signals can

still be received by any walkie talkie using the same channel, and can deplete the charging process

Remote not charging?


the battery can be charged whenever you want to charge it. There may be an issue with the cradle. can you please follow steps below and reply back with the answers?


1) Ensure the cradle is plugged into an active AC outlet and the LED light on the cradle is on. There is a switch on the bottom of the cradle to control the brightness of the LED, set it to the highest. Try different outlets if needed. Does the LED light turn on and stay on (does not blink)?
ANSWER:
2) Remove the battery. Place the remote on the cradle and check the LCD screen. The LCD screen should display a 'White' screen with possible colors before going off. Try this a few times to confirm behavior. Did the LCD turn on briefly?
ANSWER:
3) Reinsert the Battery. Have you charged the battery for at least 3 hours? If no, please recharge the batteries for at least 3 hours.
4) Did the battery ever boot the remote? If yes, please continue troubleshooting.
ANSWER:
5) Remove the battery. Check the 3 gold contacts on the battery to see if there are markings on all the contacts signifying it was connected correctly to the remote. Did the battery have markings on all 3 contacts?

My 880 will not charge I used this 2 years ago and it worked The remote still holds the old settings I now want yo use it but the unit said battery low recharge. I tried to charge it but it would not...


There is a trick with these remotes. Take a tiny piece of paper and
wedge it in between the battery and the side of the battery compartment
opposite the battery contacts when you insert battery.
This will apply more pressure between battery contacts and remote.
Now your harmony should properly charge up overnight.
Had the same problem with mine and the paper trick fixed it.
Was even able to use the old battery again.
Has something to do with the three contacts on the battery.
All 3 need to make good contact.

RCA headphones - nicad or alkaline batteries WHP141


BATTERY INSTALLATION AND INFORMATION
Your wireless headphone unit requires two rechargeable AAA batteries.
Rechargeable batteries are uncharged when you purchase them. Before
you can use the wireless headphones, the batteries must be charged for
16 hours. Follow these steps to install and charge the batteries.
Installing the Rechargeable Batteries
Take care to follow these steps to correctly install the batteries.
1. On the right headphone, locate the battery compartment (1).
Use the finger depression on the compartment to turn the battery
compartment cover counterclockwise to remove the cover.
2. Insert two AAA rechargeable batteries, carefully following the
markings inside to ensure the batteries are inserted properly, with
the + and - ends in the correct positions.
3. Replace the battery compartment cover.
Charging the Rechargeable Batteries
To recharge the headset unit, follow the directions below. Note: The
cradle/transmitter on the WHP141 is not a recharging cradle, although
you may place the headset in the cradle during recharging.
Follow these steps to recharge the NiMH rechargeable batteries.
1. Make sure the ON/OFF switch (2), located on the right headphone,
is in the OFF position.
2. Connect the AC/DC main power adapter to the DC IN power
supply socket (11), located on the back of the cradle/transmitter.

cradle/transmitter or placed next to the unit. If the headphones are
connected correctly, the charging LED indicator light on the
cradle/transmitter (8) illuminate.
