Battery BT162342 / BT262342 BT183342/BT283342 BT166342/BT266342 2.4v 800Mah Battery Pack for VTech CS6114 CS6419 CS6719 AT&T EL52300 CL80112 VTech CS6719-2 Cordless Handsets (Pack 4)

They are batteries, and they work.

These work great, just as well as name brand. So easy to install my 91 yr old mother did it herself.

Excellent product. Just what I wanted and needed

So far so good, the phone I put one of these in seems to be working fine and doesn’t require constant charging.

This is a great OEM Battery Replacement Pack and is exactly as the Product Page described. It seems to be made of High Quality Materials and has been working great for me. I'm VERY happy with it and do recommend it.

Work great

Perfect fit for my old Vtech phones bringing them new life!

We have had our cordless VTech phones for awhile. Our batteries wouldn't hold a charge for longer than 30 minutes or so. We had to make sure the phone was always on the base charging. I bought these to replace all the old batteries. It was wonderful to pick up a phone I set down in another room and have it still be charged enough to use it.One of our cats nocked a phone off the charger during the night, when I woke up I was pleasantly surprised that we still had a "full" battery.If these batteries didn't work I was going to have to purchase new phones. This has extended the life of the entire phone system.
