Model Forum / Radio Controlled / Air Models / September 2010Lipo Battery shelf life of unused cells
I read an article somewhere that advised against stockpiling Lipo batteries. The article compared Ni-cads which are shipped uncharged (formed) to lipos that are partly charged when they are manufactured and are shipped that way. This partical charge starts using up the usefull shelf life or so the article stated. Is this correct or did I remember the artcle wrong? > I read an article somewhere that advised against stockpiling Lipo > batteries.

There are some people now saying to fully charge your LiPo's before storing them for any length of time. The instructions that came with my batteries says to store them in a balanced 3.8 to 3.9 vdc per cell when not in use. This article says the same. http://www.rctoys.com/pr/2007/09/25/lithium-polymer-battery-winter-storage-lipo- care-lipoly/ The packs that I have had outlasted my NiCad packs as well as my NiMh packs using 3.85 vdc as the storage voltage. I use a vented .50 caliber ammo can to charge and store my LiPo's.

My limited experience has been that Lipos that were on the shelf will self discharge, sometimes to below the lower limit set by some chargers. So far, I've been able to eventually balance charge and then cycle them. I believe that this can restore them to 80% or better of original capacity. |
