1. In either case, the battery must not be overcharged by more than 1 % above the rating. 2. For these reasons Li-Ion is quickly becoming the most popular choice for cellular phones and portable computers. 3. It is worthwhile to compare this charge curve with that of Ni Cad and NIMN batteries. 4. Finally, the microcontroller needs to control the charge current to set it in full charge or trickle charge mode. 5. In contrast, charging a Li-Ion battery is actually a fairly straight-forward process of voltage limiting, assuming that the precision requirements are met. 6. Unfortunately, it is never possible to realize the entire capacity of the battery due to internal losses. 7. Of course, losses are present that do slow down the total charge time.
