I have a couple lithium batteries and left them on the shelf for a while, maybe a year.
Now they read only 2.64 volts instead of the 14.6.
These seem to have discharged on the own as I have an Odyssey AGM next to them and it's at 12.7 volts and has been still the same amount of time.
If these are sitting around how often do they need to be charge back up?
Is there some special way to charge them back up when they get that low?
