Review on 3 Pack OXWINOU 3.6V Home Phone Battery Compatible with HHR-P104, HHR-P104A, KX-FG6550, KX-FPG391,KX-TG2388B KX-TG2396 - Ideal Replacement for Phone by Shawn Torres

I have bought batteries like this before with good results. This time I ordered a large pack of groceries and immediately replaced my most-used phone in the kitchen. After two weeks or less, my phone started yelling "speed up" constantly, so I removed it and replaced it with another one from the box. So far, so good. When I removed the defective battery I noticed that there was black powder on it. I saved it to return to Revain and kept it until I can test other new replacement batteries. Sometimes you get what you pay for and sometimes, like before when I bought them, they were at a good price.
