When I first got into this hobby around 2008, I understood that lithium-ion batteries have a finite lifespan, but I didn't have any way to monitor the ravages of time, except to try to notice when a battery didn't seem to hold a charge for very long. Also, I didn't have a label-maker at the time, so I didn't print labels for the batteries with the dates I purchased them, so I could track their ages.
Well, thanks to my RC hobby, I now have a super-fancy charger that can charge multi-cell LiPo/LiCo/LiFe/NiMH/Lead batteries, as well as discharging them to measure their residual capacity, so I set to work testing my stash of RCR123s and 18350s. I charged each battery using my normal charger, then let it sit for a day, then tested its residual capacity. Here's what I found:
All in all, about 2/3 of my battery stash has lost more than half of their original capacity. I'll be making a trip to Best Buy to recycle some batteries in the very near future.
