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: base does not charge handset

If all 3 handsets fail to charge on the base unit that leads one to the conclusion that the charger with-in the base unit has gone bad and I really don't know of any fix. Thank You. Jerry

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:

go to www.uniden.com for customer support here is a direct link to some frequentlt asked questions http://www.mycusthelp.com/uniden/supportfaq.asp?sSessionID=&lstFilter_a=&lstFilter_b=&lstFilter_c=&txtCriteria=hanset+won%27t+connect+to+base&optcond=2&iStartCount=1

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.

DCT5 and DCT6 models: Press menu on the handset. Go to System Reset and Press select. Go to Deregister HS and press select. Arrow up to yes and press select. Then go back into the menu. Go to system reset and press select. Arrow down to Replacing the base and press select. Arrow up to yes and press select.

SOURCE: Uniden DECT2085-4WX: waterproof handset displays "Please Wait"

Hey! I have the SAME exact handset. I HAD the same exact problem except this is what you NEED to do:



On the bottom on the handset, there are two "HOLES".

There's a smaller "rubberized" hole and to the right, a later "Double Layer" hole.

The a ball point pen and GENTLY push into the lager, "double layer" hole.

You will then hear a CLICK or a POP. THIS IS OKAY.

Your phone should now be placed on the charger for at least 25 hours prior to first use.

This procedure will ONLY need to be done ONCE.

This is necessary because the battery pack was factory installed by Uniden, therefore the installed battery is NOT "contacted" to the phone's circuit, yet.

WHEN YOU "CLICK" the SEAL w/ a BALL POINT PEN, you are "CLICKING A METAL CONTACT" inside the phone, which causes the battery to make contact with the phone.

After this, I AM SURE YOU WILL NOT have this problem again! :-)

HOPE THIS HELPS!!

How do I rescue my BT Freestyle 750 from being stuck "Searching" and remedies that are "Not Possible"?


Have you tried removing the batteries and letting the internal power decay for an hour or so - in other words try to get them to forget what they were. Then replace batteries and try again. I guess you've consulted the user manual, is there a reset button hole anywhere on the base unit? The sort you stick a pin into.

BT Freelance XD8500 - one handset has totally "died". Anything I can do to restore?


just change the battery for new one and you will have miracle...

if memory serve correctly there is two "aaa" batteries in the unit, look how polarity goes!

to test - just insert standard "aaa" batteries and see if unit is resurrected, if so buy re-chargeable batteries, insert and enjoy! check an dswap charger (base) unit, rotate handsets between bases as well, base maybe not charding correctly, check pins on the bottom of the base.

if these do not work - buy new unit, it is not really worth repairing...

hope this will help you solve the problem - do not forget to vote...

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.)

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.

Uniden 2.4 GHz cordless phone won't register to base


Same happened to me. Unplug the base from power and the phone line for 30 minutes. Same for the handsets - all. Take out the batteries. Retry. After it says 'registration failed'. Leave it in the cradle. Several minutes later it found itself.

Phone holds charge from 12-55 min. and then goes dead


Your handset or charger has gone bad (provided you installed rechargable batteries), or both. The previous user may have installed alkaline batteries (is their a white powdery residue in the the charge compartment?), and that can ruin the charge circuit. Either way, you probably need to contact repair. You can go to www.cordlessrepair.com
