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 Wentronic GmbH.
B.
Under condition where normal current flow through the battery will increase , the battery should not
be connected in series with the power supply.
C. When connecting a lead wire to the battery. direct soldering or direct spot welding to the battery
should be avoided.
D. In the case of soldering, practice it at the following condition; temperature of solder ; 270°C and
less , soldering time : 5 sec.
E. In the case of automated soldering, dip only the battery terminal in solder bath and be sure that the
battery is not stopped , nor fallen in the bath.
F. When the battery is used in apparatus which heats , set the battery away from the heating part or if
the battery is near the heat source , isolate them and design the insertion so that the temperature at the
battery is 60 and less.
