Hi, I am working on a piezoelectric energy harvesting project. i was able to use my piezoelectric to charge up my AA NI MH battery 1300mAH from 0.93V to 1.201V. However, once i removed the battery from the battery holder, the cell voltage starts to drop without being connected to any load.
Anyone know what might be the reason to this?
