Unitech chargers can charge for the Ni-MH,Ni-CD and rechargeable alkaline AA/AAA/C/D batteries models.They are three types as quick charge, standard charge and slow charge,Unitech use the voltage,time,temperature and micro computer technology to control the chargers charging 2-8 pieces Ni-MH and Ni-CD rechargeable batteries respectively. We have several methods to control the charge process: minus differential voltage(-dV)，zero differential voltage(0 dv),maximum time(Tmax),maximum voltage(Vmax).Furthermore,Unitech chargers have good functions such as charge over-voltage protection,short circuit protection,overheating protection,battery reversed connection protection and over-circuit protection.other functions include auto-identifying the charge state,
Showing the malfunction battery,etc.The Unitech chargers adapt to the voltage used all over the world.And the most important information is that the Unitech chargers have got the GS/CE/SAA/UL certificate.
