Batteries in phone but message says insert batteries. Original batteries in phone

I will start by qualifying some answers regarding your device.

  1. Your device was working fine before this issue came up.
  2. This is not a new phone with a new battery install.
  3. The battery is removable.
If your phone/battery was working fine and this happened all of a sudden, then try the following.

  1. Open the phone and remove the battery. Leave it out of the phone for a full minute (don't leave phone on charger while doing this.)
  2. Re-insert battery into phone and power up the device.
  3. If it starts up, then all is well. If not then you may have a bad battery.
  4. If it fails to start, there are two possibilities:
  • Battery is bad, old.
  • USB port is bad and not charging the battery.

As we all know, batteries have a life expectancy given their use and care. Most every phone I have ever purchased came with a statement regarding the "life expectancy and care for battery." It is generally recommended that you let the battery drain all the way down before recharging it so as to "condition" it to hold a charge longer and increase it's life. Also, it is not recommended to leave your device plugged in all the time (past the point where the battery is fully charged.)

Perhaps where you live, there is a phone store which specializes in phone repair, not a branded retailer like "Verizon" or "Sprint", but a repair shop. Do a search for one close by and they will be able to test the battery. Also, you may have a battery store which deals with only batteries who can test the battery for you.

Hope this helps.

Will my land phone anser machine work even when batteries are dead.

The answering part of the machine will probably work as it is powered by the phone company circuit. If you do not put batteries in the BASE unit, it is line powered and will continue to work if batteries are dead. However, your handsets will not work, they will not ring and you will get no dial tone as they will not transmit a signal . A hint is to replace the batteries with new nickel-metal hydride batteries to assure long battery life if you have replaceable battery capability. Mine have lasted 10 years so far and still going strong!

I have a Uniden Integri sound Power Mac 5.8 ghz. One of the three phones does not register the caller ID. How can this feature be restored?

We have a similar problem with one of our handsets- except that in addition to the caller id, none of the other functions work. We've also noticed that we can get only about 10 mins of talk time on that particular handset before the battery goes dead. The manual says that if the battery is weak, none of the other functions on the phone will work (in order to conserve battery life). This seems to be our problem.

Plantronics model 340. The battery keeps dying in this model headset, this is my wife's second headset in 8 months. Is there a trick to get more battery life from these headsets?

Plantronics sells a pice of **** what works only a short time. For example any hearing aid you by you can replace the battery but here is build that way for one reason.... they want you to by a new one and create more waste. Soluition: Do not by that brand!

I have a Plantronics with a headset, but the battery does not last a day. 1- is there a phone with a larger storage compacity? Sleeples in Toronto. Thank you

if the battery is to the headset then most likley the device is faulty, unless you talk alot. on the headset package it displays the amount of talk time. if you do not have the package, call radio shack, and give them the headset modle # and they could tell you the talk time(i say radio shak because it is a small store, so the associats have knowledge of most store items).

if it is your phone battery, get a new one, let it charge fully, LET THIS NEW BATTERY DRAIN COMPLETELY UNTILL THE PHONE CUTS OFF BY ITSELF, after this, let it charge fully again and its ready for use. (this gives the battery maximum life).

RCA model 25110-replacent batteries

I, too, have this model phone and love it. The headset battery barely lasted 9 months. I've been bumped around to many places including Thompson, Radio Shack, etc. I do believe Thompson (800-338-0376) has the battery for the HANDset, but they DO NOT have the battery for the headset. The HEADset battery is available through (on the internet) (866-925-7278). This shipping document gives you the pricing info:

RCA BATTERY/ LI-POL 52707 $20.99 1 $20.99 Sub Total: $20.99 Shipping/Handling: $7.95 Tax: $1.26 GRAND TOTAL: $30.20

You may well find that the HANDset battery is available there, also. The RCA HANDset battery part number is 5-2683. You will need this to cross reference if you use
Warning: Radio Shack will say that they have the replacement battery. I had to send the one they ordered for me back to Radio Shack - - don't need to say more!!!

Hope this helps.
