basically i m using the battery for a robot alarm clock, it use an Light Dectating Resistor to seek for light spot in a room for recharging everyday
my robot actually consume not large power. It can sustain without recharge for around 1week with 3 AA battery.
for my case, which the battery will not fully discharged daily and will be recharged daily, so i think it is better to include an Charging ICs? The Ni-Cad/Ni-MH battery charger from Maxim-IC or Texas Ins or Programmer Charging ICs such as PIC?
