I have a CTP8600 Cordless phone made by Coby in 2003. The battery pack for the handset is apparently no longer charging. Coby has stopped making (or supporting) this product. I would like to replace the battery pack. That was made by Great Power BAttery Company LTD in China. The part number appears to be 3PH-AA600--S-X24.

check that you got the right make of battery for the charger
some phones use a nicad battery and others use a lit ion battery
2 different recharegable batteries -- 2 different chargers required

There are a few reasons why a battery won't charge. Make sure that the contacts on the phone and the charging cradle are clean. (Unplug the base or charger.) A pencil eraser is good initial cleaner; electronic contact cleaner sprays are a second option. Remove the battery and check the contacts inside the handset and the battery as well. Next replace the battery pack. If you add a comment with your phone's model number, then I can try to find the correct battery. (Stores like Battery Mart may have a compatible battery.)

The final possible problem is that the charging system is bad. If your phone has multiple handsets, try a different charger. If the phone allows you to add handsets, try getting a new handset. The new handset will come with a new charger. (I've never seen the chargers sold without the handset but you could try Uniden customer service. If the base station is the only handset cradle, you'll probably need to replace the phone if a new battery and clean contacts don't work.

If your Uniden phone is under warranty, contact the company.

I hope this helps.

Usually when made they come with rather poor quality rechargeable batteries in them to save money.

Lots of sellers on EBAY from China etc are selling them now there, got two of the packs, open phone, unplug, remove battery pack, install new on.

I got a few that came in five days from Hong Kong duty free for under ten dollars for two sets of the batteries.

My money would be the batteries are trash.

Usual life on new original ones about one year.

Apologies for asking the obvious, but have you removed the battery cover on the handset to ensure that the battery pack is connected? There should be two wires from the battery pack, black and red, which terminate in a plug. That plug must be securely fitted into the corresponding socket inside the handset.

If that is all OK, then I suggest you swap the battery pack from the working handset and see if that works in the one that will not charge. By doing this you should be able to determine if it is the battery at fault, or the handset.

Well.. You may not like my solution.. because I had the same problem with the same phone as you have and everything I did was not successful. WHY you ask??

Because it sounds to me that the rechargable battery itself is either defective, worn out \Or maybe the phone was dropped causing the battery damage, due to the sudden jolt when it hit the floor, as these rechargable batteries are not indistructable??)

I bet if you go toUNIDEN site or the electronic store and replace the rechargable battery, with a BT800/BP800 Battery Pack as what I had to get (but check make/model of the battery pack you already have installed in handset), your phone will continue to operate as if it was new again. I paid about $30- for my battery pack.

Hi.. Let me try to help you if I can... I'd like you to check a few things,

1) Open battery cover on handset & make sure that the battery pack is installed correctly, and not upside down. Also make sure the little wires that come from battery pack are plugged into the tiny jacks of the phone (usualy red & black wires) in handset is fully attached & pushed snuggly into the handset... and if No wires, check to ensure the part that does connect the battery to handset is not covered with a plastic film of tape or paper as right from a manufacturer they sometimes do that to preserve length of battery until product is sold to you..

2) Check the bottom of the handset phone, that sit in the cradle of the electric part of the recharger, and make sure there is nothing like plastic or paper covering the connections between the bottom of the handset and the charger. Make sure there is a full on connection for a full charge to the handset. As with some cordelss phones Ive had the red LED light will not come on if there is something blocking a full connection for a charge.. The red LED light on base, only comes on when the electricity is flowing into the handset. The slightest tilt not allowing handset a full charge, wont give it a FULL charge.

3) You say " NEW. Out Of The Box" I hope when you connected the battery pack into the handset, and made sure it was connected right, you then allowed handset to charge at least a FULL 12 -24 hours before trying to use your new cordless phone. as the batteries right out of the box, are rarely already fully charged when any cordless phone is bought and then it does need 12 - 24 hours for a FIRST FULL CHARGE...

If you can check all 3 of these questions, and let me know how things are back on this posting, if you stilll can not solve the problem after a full charge to battery, I may have some other ideas that can help.

Good Luck

Does the Phone Power Up?
1. When you pick up your GE cordless phone and press a button, the phone should beep as a confirmation that a button has been pressed. If the telephone handset does not beep, or if it does not respond to any buttons, the battery may be in need of a recharge. Verify that the cordless phone base unit is plugged in to an electrical source, then place the handset into the charging cradle. If no lights illuminate on the phone, or if charging fails to correct the issue, clean the metal charging contacts on the cordless handset and place the phone back on the charger. If it still fails to respond or to charge, the unit may need to be serviced or replaced.
Does the Battery Hold a Charge?
2. If the cordless phone charges up and appears to be ready for use but dies after only short periods of use, the internal rechargeable batteries may need to be replaced. Replacement batteries are widely available at electronics and discount retail stores. Note your phone's exact model number, as this number will be necessary when purchasing a replacement battery.
Listen for a Dial Tone
3. If the GE cordless phone powers on, and beeps when you press keys, but no dial tone is heard, one of three problems is the likely culprit. The phone's batteries may have an insufficient charge to fully power the phone, a condition that can be corrected by simply placing the phone back in the charger. If the batteries are charged, but no dial tone is heard, it is also possible that another telephone in your home or office is "off hook" or in use; verify that all telephones, fax machines and modems are securely on the hook. If there is still no dial tone, your telephone service may have been disconnected or require service by your local telephone company.
Listen for Static
4. On some GE cordless phone models, particularly older models, static may be heard if the radio signal between the handset and base unit experiences interference. Common sources of interference include unshielded electronics, appliances, and radio transmitters, as well as high-tension power lines. If your phone offers an option to change channels, try several different channels to see if the static is eliminated. If static continues to exist, or if static can be heard on wired phones sharing the same line, your telephone line may require service.
Verify Your Handset is Registered
5. Some models of GE cordless phones may display a message on the display screen that the handset needs to be registered. If this message appears, move the handset close to the base unit and press the "Prog/Mute" button near the bottom of the handset. Next, press the "Pager" button on the base unit (your handset may instruct you to perform this step). Finally, press the "Prog/Mute" button on the handset one more time to complete the registration process. Your GE cordless phone should now work correctly.The GE Cordless Phone brand is designed to deliver the conveniences of cordless home service with quality sound and features. There are many models of the GE Cordless Phone. The most current models, including the DECT 6.0, have standard features such as call waiting, caller ID, visual ring indicator, phone number memory and digital answering systems .
   
6. Before you use your GE Cordless Phone, ensure that you have all the parts. Your cordless phone package should include the phone base, a handset battery pack, a battery compartment cover, the cordless handset, a wall mount bracket, and a telephone line cord and AC power adaptor. Once you have confirmed that you have all of your parts, insert the handset battery pack into the handset and replace the battery compartment cover. Insert your telephone line cord and the AC power adapter into the phone base. The phone base identifies the telephone line as TEL LINE and the adapter as AC. Plug the phone base into the electrical socket. Place the cordless handset into the base. Allow the phone to charge for at least 16 hours before its first use. Failure to fully charge the battery before its first use will result in poor battery performance.
7. Once you have fully charged your phone, you can proceed with setting up your phone's features. If your cordless phone includes an answering system, complete this setup process first. Turn on the answering system by pressing the on/off button. The message indicator light will display. The cordless phones are defaulted to English as the selected language. To change your language preference, press the "Skip" button for two seconds. The language will change to Spanish. Next, you will set up your voice time and day stamp. While the answering system is on, press the "Answer" button on your handset for two seconds. The phone will enter the answerer mode. Press the "8" key. This will take you to the time/day setup menu. Use the number keys to set the hour and minutes. Use the volume up and down arrows to set the AM/PM. Press "#" to save. The cordless handset will also require that you give it a name. Press the "Mute" button for two seconds until the handset reads "ENTER NAME." Enter the name of the handset by using the touchtone keypad. Press the "Mute" button to save. Enter the default area code by pressing "Mute" until the phone displays "AREA CODE." Enter your three-digit area code and press the "Mute" button to save.
8. GE Cordless Phones are designed to be simple and convenient to use. To place or answer a call, press the TALK button. You can pre-dial a number by dialing the number before pressing the TALK button. When you are ready to make the call, press TALK and the phone will dial automatically. To answer a call that is waiting on the other line, press the FLASH button. If you experience call interference or bad reception while on a call, press the CHANNEL button until your line clears
