Unused 510 Battery Charges

[WillieB69]

Since I got my box mod, I'm keeping my 510 mega batteries as backups. I charged both a couple of days ago and stuck them in my carrying case that goes everywhere with me. I'm curious how long the charges will hold on the 510s as long as they're not used.

It will slowly decharge over time. It's a condition of lion batts. They leak their charge over time- measured I believe in months.

According to the specification it's not good to totally let one discharge to *nothing* by storing it a long time without a charge (6 months?). I'd give them a charge from time to time if stored for long periods.

So I don't have to worry if something happens on Tuesday next week and I need a backup?
Awesome.

What about new ones that have never been used? Should they be charged from time to time? maybe once every 6 months? I have 6 regular 510 batteries and I've only used 2, I always have one charging while the other is in use. I have a second regular wall charger and a PCC so I could charge 3 batteries at once if I ever needed to.
