Rating : - It doesn't work! I purchased this Ultralast 1616 for my car remote. It doesn't work; even though it measures 3.26 volts. I think it is just too thin to make contact with the contacts in the remote. I tried bending up the contacts in the remote and still not luck. I found some Energizer brand cr1616 batteries and they are working perfectly. BE AWARE, you can not return this product.
