I've read about the DSE901 doing a self cleaning in a few posts. Does anyone know how it knows when to do it and how to defeat it? My batteries have been doing funky things here lately (activating by themselves for no apparent reason). At first I thought they might be getting clogged with eliquid, but now I'm not so sure.............Also - does anyone have a good way of cleaning a battery that has gotten eliquid in it? Thanks.
