What buyers say about 5 Maxell CR1620 3V Lithium Coin Cell Watch Batteries
I was able to find a 5-pack of batteries for less than half the price of a brand-name battery, and I used two of them to replace the batteries in our car keyfob; both batteries work as expected and significantly increased the range of the dying batteries they replaced.
I have only used 2 of the 5, but so far they are working well. The measured voltages of both were between 3.11 and 3.14.
