Hey guys -
My question is regarding li-ion individual cells and storage charging - I cannot find a _single_ li-ion/18650 charger that is advertised as having a 'storage mode' - yet I see the same advice on storage, discharge down to around 40-50%.
I have a little background with li-po packs - for those it is drilled home that you really (REALLY) need to partially discharge / put a 'storage charge' on them if they will not be used for a while. I only use my li-po's a few times per year, so i have a "nice" RC-car style balanced charger that will discharge them down to 3.85 volts per cell (and then they go in a refrigerator )
Am I missing something? Do li-ion's degrade at full charge / temp to a much lesser degree than Li-po? Do I just not know how to search correctly [ ] ?
Anecdotally, I have a few 3400mah orbtronic ICR's, some from about 18 months ago, some new; none have seen a ton of use, but i do notice that the new ones are taking > 3000mah, and the 'old' ones are 2500-3000.
Thanks!
(FYI specifically i have a mix of protected ICR and unprotected IFR & IMR, mostly in 18650 size, a few 18350, cr123, and cr2; although I haven't found any info that is specific to charge, storage profiles for the different chemistries.)
