AdvanceTec’s Li-Ion Specific Chargers
Li-Ion batteries are lighter than other energy-equivalent secondary batteries, including both Ni-Cd and Ni-MH. However high charge levels and elevated temperatures from charging will hasten capacity loss. If overheated or overcharged, Li-ion batteries may suffer thermal runaway and cell rupture. In extreme cases this can lead to combustion. Deep discharge may short-circuit the cell, in which case recharging would be unsafe. The AdvanceTec™ Li-Ion charger makes use of VSCTM™ (Voltage Specific Control) when charging Li-Ion and Li-Poly chemistry batteries. The discharge pulse has a relaxing effect on the battery, increasing charge acceptance and allowing a charge at a lower temperature. Current is applied until the voltage limit per cell (as recommended by the cell manufacturer) is reached and then the precise voltage per cell limit (±.2%) is applied until the current declines below 3% of rated charge current. If voltage is applied exceeding the recommended voltage, it will cause a rapid and permanent reduction in the number of cycles in the battery.
