long term storage for batteries?

[brett.mayfield]

hey y'all

I have some newly recelled batteries that aren't going to be used for about a year. will they be in the same / good shape after a year of sitting on twin simultaneous chargers?

Are they Li-ion?

If so, batteries should generally be stored at 40% charge to minimise degradation. Storing them fully charged or discharged degrades the cells faster. Keep them cool and out of the Sun.

thanks Mike. yes, lithium, hcx batteries. how would I maintain 40%?
