Best & Cheapest CR1632
By far the cheapest and best CR1632 is made by PKCELL. It is comparable to energizer ECR1632 and Duracell DL1632. These name brand batteries are made to more strict quality control standards whereas PKCELL is mass made with less stringent quality control. That is not to say it is any less of a battery but if you are using a medical device or a very electrically sensitive device it is best to choose the name brand.
