We received some inquiries such as “Mechanical Malfunction”, “Short Operating time”,
“Low Voltage” when using Coin Manganese Dioxide Lithium Batteries. However, we conclude that those are
caused by “External Short-circult”.
It occurs by incorrect handling or carelessness of the battery. Therefore, please read the “Caution”
below and pay full attention to external short-circuits.
In addition, we kindly ask you to send “Caution” to selling place when
selling our Coin Manganese Dioxide Lithium Batteries to other customer.
