Question about Vtech IP5850 Cordless Phone

1 Answer

Phones going dead

We have had our phones about a year. Very recently they started displaying the message "warning! check batteries!" The manual said that means the batteries are either not there, or installed wrong. So I take them out and put them back in again, and the phone may or may not work for a few minutes, then becomes useless again. The message doesn't say anything about the batteries needing recharging, just to check them. The phones doesn't die quite as quickly in the base set as in the satellite base, but neither is dependable. Looking for replacement batteries on the vtech website, they don't even show replacement batteries for a 5850.

Re: Phones going dead

Buy a new battery from ebay.
just type in the search box, 80-5808-00-00
(the battery number)
You should be able to get a replacement for around $6 incl shipping.
This worked for me anyway. (Same symptoms you described)

Nothing shows up in the display. This has only been recently after a power glitch. The display lights when a call is made or received.

I unplugged the base unit from the wall for more than 10 minutes. Sometime after I plugged it back in (not immediately)the display re-appeared.

Channel Searching message, but phone is right next to unit

If your phone worked fine and this problem just started happening and seems to be getting worse, I would change the battery, even if the charge light indicates that the battery is charging and you "think" the battery is charged.

Most of these weird problems that start occurring in a phone that always worked fine are caused by the battery goinf dead. You can buy a replacement battery on ebay for like $6-$7 with shipping for most models of cordless phones. I sort of rehab cordless phones that I get at yard sales and at goodwills and sell them on ebay. Out of 50 or 60 so far, I have never found a broken one. I have found, however, plenty of phones that initially display all sorts of weird symptoms which are ALWAYS -- and i mean always -- fixed by a new battery. Good luck.

Phone goes to auto answer and I cannot get it out of that mode.


That message is displayed when the 2 aa batteries go dead on a partner ACS. The batteries are located on the "main" card on the bottom front below the plugs for the phones.It has a black slide bar that you push up to get the battery module out.Make sure you put the batteries in as shown on the module. Replace when finished. hope that helps.

Low battery problem


Although your batteries are exhibiting a charge memory effect a little early, it doesn't surprise me too much after the phones are in use for two years.

You need to replace the batteries in your cordless phones. These you can find at any Radio Shack. Once yo have installed the new batteries you want to let both batteries go dead from use, keep them off the charger stand for this break in period. If you can do this your phones batteries will last longer.

For more information on rechargeable battery memory effect read this article.

Out of Range

It needs to be re-synced to the base unit. Check manual for exact directions, but it could involve anything from unplugging battery and base unit power, resetting in cradle, and anything else......

Almost constantly gives "no link to base" message

I had this problem too. I popped the battery out, waited 1 minute then put it back in. Unfortunately this clears the memory of all recent calls, etc. but it immediately started working again. So far its only happened once...
