?Initial charging: Batteries are analyzed for possible damage; forming and auto-repair is attempted by LED indicator for each charge bay? End of charging: As batteries get fully charged the respective LED indicator will change. At the end of charging, a small trickle current o compensate the gradual decrease of energy over time so that keeping battery readily charged.? Conditioning: o Restore the decreasing ability of Ni-Cd batteries, help to retain the full capacity over time (memory effect). With the push o button, all the batteries discharge will automatically charge again? General: o Ni-Cd/Ni-MH battery (AA or AAA or any mix thereof); 180-5000mAh o Four independent battery bays and discharge function o Battery-full criteria: peak-voltage-detection with safety timer o Charge current: 1.2A (AA) and 300mA (AAA), maintenance current at charge end o Detachable mains adapter: 90-264VDC and car plug for 12VDC
