Small Lithium ion secondary batteriesCT04120

Features

Quick charge characteristics

  • High-rate charging (10C) is possible, and no charging IC is required.

Excellent discharge characteristics

  • Continuous discharge with a maximum discharge rate of 10C is possible. In addition, since the
    internal resistance is low and the voltage drop is small, stable discharge is possible even under
    a large peak load or low temperature.

Long cycle life

  • Charge (capacity) recovery rate keeps over 80% even after 5000 cycles. It can realize
    maintenance free design.

High safety

  • No thermal runaway occurs because of using chemically stable lithium titan.

  2. Air transportation

    Although this product is applicable to UN38.3, it conforms to the Special Provision 188, therefore it can be shipped as an exemption from Class 9 dangerous goods.

    However, in air transportation, it is necessary to be transported as Class 9 dangerous goods in accordance with IATA DGR (Dangerous Goods Regulation) and Packing Instruction 965-Section IB. In addition, when the number of package is not more than one as per single consignment, it can be shipped in accordance with Packing Instruction 965-Section Ⅱ.

    The above regulation is effective only for the packing condition at the time of shipment from the Murata factory. If any problem happens under the packing condition other than Murata specification, Murata would not have any responsibility for the compensation. For the details of transportation regulation, please refer to the latest edition of IATA DGR (Dangerous Goods Regulation), IMO IMDG Code.

  3. Return of damaged or defective products

    Air transport of damaged / defective lithium-ion batteries is prohibited under the IATA DGR (Air Dangerous Goods Regulations). If you are considering returning it, please contact us in advance.
