I think the actual battery manufacturer for the Ultralast UL357's I mentioned
(NL markings on the cell) previously,whose specs I could not find, may be this
company "New Leader" whose blurb I have copied here:
>
New Leader Battery Industry Ltd. was established in 1983. We are one of the
leading battery manufacturers in Hong Kong. With our advanced and comprehensive
production facilities, our batteries are endorsed globally by electronic toys,
gifts and premium industries. Our major products include alkaline manganese
button cells, silver oxide button cells, lithium manganese dioxide batteries,
zinc chloride primary batteries, 9V 6F22 and 12V 23A 27A batteries. We believe
that mercury free batteries will propel us towards the leading edge in world
battery technology. Mercury free batteries will also fulfill our mission
statement towards environment friendly batteries. Since 1998, we have invested
large amounts of resources to the research of mercury free alkaline button
cells. By the end of year 2000, we have successfully launched the world's first
mercury free buttons cells and gained the patent in HKSAR, China. This new
leading technology is now pending to be
patented in other countries as well. These new products are well endorsed by
many renowned toys, gifts, and premium enterprises. New leader mercury free
button battery is fully complied with EEC RoHS directives, 98/101/EC, and
91/157/EEC battery directives as well as to meet with EEC or US electronic and
electrical industrial standard. Our Guangdong Zhaoqing factories were built on
self-owned land, composing 6 blocks, with 500,000 square feet. Currently we
employ over 3000 employees and are building other production plant to meet with
the ever growing demands of our clients. We currently employ more than 300
staff in quality assurance (Q.C), research & development, and production
engineering to carry out the ISO9001 quality management system. From raw
materials, each part of processing to final products, these procedures are
under strict quality control to ensure all new leader batteries have good
quality and long time use.
