This is the only type intelligent charger handles 9v rechargeable batteries, such as Nimh, Nicd, Li-ion from 7.2v to 9.6v with LCD display. BT-C900 charger handles 4 batteries at the same time, with each battery independent from working mode and/or display content at the same time. Different working modes are under user choice: charge, discharge, test, refresh, and quick test( for internal resistance measurement). Charging current is programmable from 50mA to 200mA with 25mA per increment step. Discharging current is automatically set to same as selected charging current.

Battery related information can be displayed on LCD for each slot respectively: V, mA, mAh, h:mm(time) and IR( unit in milli ohm).

For Nimh or Nicd battery charging, -dv or 0dv termination is adopted, charger can handle 7.2v, 8.4v and 9.6v type batteries.

For Li-ion battery charging, it needs to have the battery to be protected type. Non-protected type Li-ion is FORBIDEN to be charged on this charger. Failed obeying this rule in charging none protected Li-ion batteries can lead to harzadous result, such as battery fire or explosion.
