oh.. i have not used my original eneloop charger as i use La Crosse charger.. i have 2 of these oem chargers which are still inside the package less the batteries

when you start charging eneloop through La Crosse the charger has a default mode where it start to work.. it reads the battery status ("null" if battery is "dead" already) ... i forgot which mode though when i suspect i need to refresh i opt for discharge/charge mode at its lowest charging rate of 200mAh ...it drains the batteries and then charges after that
btw, there is downloadable instruction available
