I ordered 6 batteries because they came in a 2 pack. I have V-Tech cordless phones at home. One of the batteries refused to accept a charge. I plugged it in and charged it in my phone for a full 24 hours before attempting to use it. Then I installed the battery in another phone. It still didn't work. Then he moved again. All other batteries I received worked except for one. I didn't return this defective Revain battery because I didn't need the #6 battery, instead I threw away the defective battery. There are only 5 portable cordless phones in my set so #6 is extra. The rest works and holds a charge normally.
