Question about Uniden Cordless Phone Battery BBTY0457001, BT-446 (CORCPH488B)

Open Question

Uniden BT-446 Batteries all dying at the same time

Several years ago I bought a Uniden base and several handsets. Now all the batteries on all of the handsets are reading low battery and will only hold a charge for about 10 minutes. Is this a common problem with the BT-446 battery. Will simply replacing the batteries fix the problem, or is there another issue, and would I be wasting my money?

SOURCE: Handheld won't communicate with the base

i have the same problem and it has happened infrequently several times. you probably have to deregister the handset and re-register it and rest the base and handheld to communicate since my model is different from yours there may be differences in how to go about it but for my model the suggestion is as follows:

Try resetting the phone system by using the following steps:

1) Enter the "System Reset" menu, then "Deregister HS" submenu.
2) Press volume/up or down arrow keys to select the handset ID to be de-registered from the list, then press the OK soft key.
3) Press the OK soft key. You will hear a confirmation tone. When de-registration is complete, "Deregistration Complete" appears.

4) After de-registering the handset, move to "Replacing the Base Setting" below. When you go through the deregister procedure if you get "out of range", That is okay. Go ahead and go to the next step.

Replacing the Base Setting
1) Enter the "System Reset" menu, then "Replacing Base" submenu. "Do you want to replace Base?" appears.

2) Press the OK soft key. You will hear a conformation tone. The base information will be deleted. When replacing the base is complete, "Please Register" appears, register the handset to the new base.

If your handset is reading out of range. Check the the main base and make sure you unit has power. This can be done by placing the handset in the main base to see if the charge in use light comes on.
If your main base isn't getting power please make sure the ac adapter is plugged in and is warm to the touch. If not the ac adapter would be damaged.
To resolve out of range follow the below steps.
Press and hold the end key.
Press and hold the # key.

Release the keys and select replacing base and press select.
You will see Replace base?
Select Yes and press select.
Now place the handset on the base and it should register to the base and allow for calls to be made.

DECT 6.0 cordless. Why won't it register the handset when placed on the base?


This could be several things.... the simplest is that a weak
handset battery can interfere with registration. Or,
does the handset display say "Connecting..." or
"Searching...." or "Out of Range / no power at base ..." ??

In these cases the handset is registered to another base and
must be de-registered before it can be registered again.

To deregister the handset:

Press and hold the [END] and [ # ] keys at the same time,
after a few seconds the display will say:

"System Reset, Deregister Handset"
press [SELECT]

scroll to "Base Unavailable"
press [SELECT] (chirps) press [END]

display reads "Place in base..." and it should be ready to
register.

Good luck!

Battery


Here are a few options; 1) your picture shows two bases, if that is the case, is it happening to both bases/phones, if not check terminals to make sure both are clean and connecting well. 2) if possibly exchange them, Uniden's are usually good phones, I've owned them before. 3) If you have one phone holding a charge and the other not, exchange the batteries and see if it's specific to the battery set. If so, you can purchase replacements at several stores. Hope that helps.

Phone says searching


Bring the handset that says searching into the same room as the base and see if the handset stops searching. Next unplug the handset batteries (yes from all handsets) and the base power cord (from both the base and the wall outlet). Wait a few minutes and then reconnect the batteries and base power cord. Next try to de-register and then re-register the handsets. (If you add a comment with the phone model, I'll help you with this step. Uniden has the manuals for their phones on their site: http://www.uniden.com/bin/venda?ex=co_disp-view&bsref=uniden&scat=dectphones_mnl .)

If this doesn't help, next try a new battery (and make sure that the battery is fully charged) for the phone. (If the phone is under warranty, contact Uniden. Note: batteries lose their ability to hold a charge over time. This includes the time on the shelf in the package.)

If a new battery doesn't help, then there is something wrong with the handset. Decide if it is worth having the unit fixed if the phone is out of warranty.

I hope this helps.

(I'm assuming that both handsets are cordless. If you have a corded/cordless model, then check that the base has power before you go farther with the above diagnostics. The power brick should be warm. We had a cordless phone on a power strip (UPS) that got turned off. The handset was searching for a signal that wasn't being sent. If you have power to the base, try sending the Find Handset message. The problem could be either the base or the handset not sending and receiving the signals between them.)

HOW DO U CONNECT THE HANDSET TO THE BASE.ALREADY TRIED THE REGISTER BUTTON,DID NOT WORK.IT CAME WITH NO DIRECTIONS,WE BOUGHT AT A FLE MARKET FOR 5 DOLLARS.


Are you sure of the model number? The D1680 should register the handset when you put it on the base for 30 seconds. (You should see Handset Registering followed by Registration Complete.) Then press Talk/Flash to check for dial tone. On this model if the registration fails, charge the battery (or replace the battery and then charge that). Then repeat the registration.
The manual for the Uniden D1680 is available here: http://news.uniden.com/pdf/D1680om.pdf .

For other Uniden phones, like the DEC1060, you need to navigate through the handset menus to find the Handset Registration command. Then press and hold the Register Handset (Find Handset) key on the base for 3+ secondsThen the base and handset will synch. (Low batteries could interfere with the process.)

For the D3288, you access the base menu for Register Accy and then press and hold # on the handset for 30+ seconds. (You will see Registering followed by Registration Complete.)


Additional Uniden cordless phone manuals are available here: http://www.uniden.com/scat/cordlessphones_mnl .

I hope this helps.

(with a flea market phone, my first suggestion is to try a new battery for the handset. They only have a given number of recharge cycles and you do not know the history. However, sometimes the chargers do fail and a new battery will not work. In that case, the phone should be replaced. It isn't worth the cost of out-of-warranty repairs.)

My uniden phone says - out of range


Uniden wxi477 out of range fix

This problem arises when the handset does not communicate with the base.
These are the steps:
1: Deregistering the handset
2: Registering the handset to base

Deregestering clears the stored (incorrect) base information on the handset.
Reregestering allows the base to assign a new ID for the handset.

Deregistering- press and hold the OFF (red button) and the # button on the handset for 5 seconds. select base unavailable and press OK. Are you sure appears. select yes and press OK. you will hear a confirmation tone. The handset will delete its own base information without trying to contact the base. It will now display MODELS VARY PLACE HANDSET ON THE BASE FOR REGISTRATION.

Registering the handset with the base- Make sure the tel. line and power is plugged into the base.
Press an hold the register button under the base (located between the tel. line and yellow power socket under the base) for 5 seconds until the red light flashes. At the same time press and hold the # button on the handset for 5 secs. You will hear a tone and It will now display REGISTRATION COMPLETE.

If it says registration failed: Retry the registration steps. Make sure the handset have enough battery power. If not charge for 15-20 hrs.
Check your connections on the base and make it is getting power.

The Steps above was my fix for the uniden wxi477 out of range problem.

Good luck.

Is the phone under warranty?

You should check that the battery is a genuine Uniden one. (Check them all).

From personal experience - I had the same problem with a phone I bought (supposedly) brand new - though mine would last about 10 minutes. The batteries which came in the box were not genuine Uniden batteries. I had to buy new ones direct from Uniden (to be sure) - and no problems since..

I have since been told that sometimes the original batteries are stolen and replaced with cheap nasty ones - before they even get into the shop.

Same thing can happen with computer software - they make copies from the original cd. Then they just need a vacuum packaging machine to make it look like it has never been used.

ADDING HANDSET SAYS OUT OF RANGE


A search of Uniden support only said to call 1-800-297-1023 with handset registration issues. The rep picked up quickly and walked me through the reset procedure. Here it is step-by-step:

1. Remove battery
2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it's workable)
3. Screen will be blank. Immediately press the right soft menu button.
4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok
5. Remove battery (yes again)
6. Reinsert battery (this time there's no need to hold down any buttons)
7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)
8. Place handset on base and it will register as normal

Out of range, buttons don't respond, battery won't hold charge


when you have a problem with anything under warranty, you take it back for new units or a refund and anything under 12 months old is under warranty
if you have lost the receipts get a copy of your bank statements as that shows where it was bought , how much it cost and when
That is a legal document to trigger a warranty action or refund
