Although only the 2 outer pads are actually used by the PCB to provide voltage, it is a good idea to tin the middle 2 pads as well. It’ll charge several 20mm type coin cell batteries. Similar projects worth following.

Now what if you added a few resistors and a dip switch too? Testing the newly charged batteries lkr2032 my POV fidget spinner.


Even though surface mount tabs are available, these datadheet will be damaged if put through a surface mount reflow process due to the high temperatures involved. TP is a great little chip. Safe for transportation and general shock. Applications include laptop computers, PDA, IC cards, electric clocks, watches, remote control keys, cameras, toys, etc.
