announces the CG-320A Pin Type Li-ion battery featuring a nominal capacity 15.0
mAh with a diameter of 3.65 mm, length of 20 mm, and a weight of 0.6 g. The
battery is suitable for powering small applications such as wearable devices.
The cylindrically shaped rechargeable Li-ion battery features the reliability
and output required for near-field communications (NFC).




These pin-type batteries were introduced by Panasonic in late 2014 but
didn’t become available in production quantities until mid-2015. The CG-320A is
the latest version of the pin-type line. It seems to be just in time for the
full-scale introduction of wearable device products, anticipated widely as the
next wave in mobile devices after smartphones. Rechargeable batteries, the power source for wearable
devices, will be small and light as well as feature a high level of reliability
and performance. An exterior stainless-steel can, provides dimensional stability.
Applications include wearable devices, electronic pens, hearing aids, measuring
devices, NFC, and specialty eyewear. The standard voltage range is 3.0 to 4.35
V, with a stop charging requirement of 4.45 V, and a do not discharge voltage of
below 2.7 V.
