1. Precautions when using Coin type Manganese Dioxide Lithium batteries

A. Coin type Manganese Dioxide Lithium battery is a primary battery and cannot be charged.

1) When used in memory back up circuit , to avoid a current flow from the main power

source to the battery circuit , a blocking diode which prevents reverse current flow

should be used .

(Refer to the following figure)

2) Low current leakage type diodes should be used . When choosing a diode , the total

electric charge by reverse current leakage should be kept at 1~2% of the nominal

capacity.

3) When using batteries , if you have any questions about detailed matters , including

power backup specification , please contact Shun Wo New Power Electronics

(Shenzhen)Co.Ltd .
