Caution! The temperature of the soldering iron is 450 degrees Fahrenheit. Do not apply melted soldering alloy for more than 15-20 seconds of time intervals.
Do not touch the tip of the Soldering iron directly onto the battery. Only apply melted solder alloy onto the battery contact tab.
Ensure that the positive and negative electrodes are correctly identified and now place the new batteries onto the battery holder.
Apply Soldering paste on the battery contact tab and then melt solder alloy on to the tip of the soldering iron and touch the tip of the soldering iron to one of the 4 specified battery contact tab. Repeat this same step for the other 3 battery contact tabs. Apply some more soldering iron alloy if the batteries do not feel rigid on the holder.
