欧美国家已开始开发一种新的可充电电池，叫镍锌AA电池(Ni-Zn电池)

镍锌AA电池: 电池尺寸同镍氢/镍镉的尺寸: IEC规格

理论电压: 1.8V

理论电压:放电1.65V

理论容量: 1500Mah

对充电器的要求:

充电器应可同时充4节AA

1.1. Constant current charge at C rate ( 1.5 amps ) until cell voltage reaches 1.9 volts/cell

在每节电池电压达到1.9V之前，1.5amps恒流充电

1.2. Maintain 1.9 volts/cell and terminate constant current and allow current to taper at constant float voltage ( 1.9 volt) condition.

当电压到1.9V时停止恒流充电，在1.9V的情况下让电流逐渐变小，

1.3. When taper current reach C/15,100 ma or when total time charge reaches 2.5 hrs terminate charge.

当小电流达到C/15,100mA或者总的充电时间达到2.5小时时停止充电

Please review this charging information and give me any recommendations you may have to reduce cost and improve reliability.
