Amazon Basics Cordless Phone Replacement Battery – 4 Pack – Replaces BT183342, BT283342, BT166342, BT266342, BT162342, BT262342

No, 2.4 volt for these. You need a battery pack that looks like 3 batteries inside, supplying the extra 1.2 volts.

The phone your asking about uses 1.2 volt 800mah
Batteries that is pretty much the same as a rechargeable double a battery …
These batteries are spot welded together inside a think wrap sleeve with leads coming out and a molex connection on the end.

Ro3 batteries are a standard 1.2 volt rechargeable size AA

They work just fine, no issues.

Yes, this battery pack should be the correct model.

Fits my vtech cs6919 phone nicely. The wiring comes out the opposite side as another reviewer mentioned, but you can carefully bend the wires to make it fit. Can’t comment on how long they last, but @ 4 for $9, this is a great deal, and I’m sure it’ll be better than my old battery.

Also, one side of the battery says “This side up”, so that’s why I didn’t just flip the battery over to have the wiring routed like the original battery.

Amazon Basics quality – no complaints!

These worked perfectly as replacements for the batteries in my cordless phones all over the house which have been brought back to life. I bought Fluoreon replacements prior and decided to go Amazon Basics this time around.

I only needed 3 but this was less expensive than the 3 packs .. remember to charge them at least over night the first day before you start talking for hours at a time and they should last a good long time

These plugged right into the phone. They charge as quickly as the OEM batteries I replaced. The charge lasts a few days in my home. Primarily as stand by since we don’t generally talk on the phone often. As for longevity of the product, I haven’t owned it long enough to make that determination.

Was going to spend 100 buck on a new set of cordless phones, got these batteries and the phones are like new again.
Perfect fit in the phone, they have a longer amp hour rating so they last longer. Very happy!

Quick delivery great price world great and got 4 for the price of one in retail stores

Excellent.

Purchased these batteries to replace old batteries in my Panasonic phones. They worked perfect. Recommend.

These Amazon brand batteries perform equally well in my phone as the Panasonic originals did.

These greatly improved the talk time of my cordless phones. What a great value.
