Rated 3 out of 5 by from Don't know, can't tell. Duracell doesn't specify whether high-drain (capable of occasional high peak current) or low-drain (capable of only continuous low drain) on its supposed 357/303 equivalence (which is it?), nor can I find competent full specifications and tests on the products.
