holy crap. I thought from the title it would be a battery that just can still hold a charge enough to be recharged again after so long. Not one that has been actively discharging non-stop for 176 years. We can't even make batteries that can be recharged and reused for that long. Unless there was some secret to it where it's able to absorb ambient energy of some sort and convert it to electric currents &gt;.&gt;
