I suspect you're overcharging it, at least at 36 hours. That's 18000 mAh! The charger can theoretically supply 2300 mAh in less than five hours. Some will naturally be lost to inefficiencies like electrical resistance and such, but from absolutely pure-dee dead, you ought to be able to top it off in less than six hours. TTYL, DougF KG4LMZ
