1.0. General
This document has been prepared to describe the appropriate cautions and
prohibitions, which the customer should take or employ when the customer uses
and handles the lithium ion cell to be manufactured and supplied by Samsung SDI Co., Ltd., in order to obtain optimal performance and safety. 2.0. Charging
2.1 Charging current
Charging current shall be less than maximum charge current specified in the product
2.2 Charging voltage Charging shall be done by voltage less than that specified in the product specification. 2.3 Charging time Continuous charging under specified voltage does not cause any loss of performance characteristics. However, the charge timer is recommended to be installed from a safety consideration, which shuts off further charging at time specified in the product specification. 2.4 Charging temperature The cell shall be charged within a range of specified temperatures in the specification. 2.5 Reverse charging The cell shall be connected, confirming that its poles are correctly aligned. Inverse charging shall be strictly prohibited. If the cell is connected improperly, it may be 3.0. Discharging
3.1 Discharging
