Just changed a leaking super cap from a soil/temp. transmitter, after “eating” two batteries. Both batteries lasted for about 2 months each, I first suspected the solar panel since it lost the glossy look after 2 years of operation, but on a closer look I found the cap. I should have ordered more than one when I did but?.. sure a 3.6 V rechargeable puts a strain on the cap since the circuit is designed for 3.0V .

p.s. this is a leaking super cap
