to Charge Lead-Acid Batteries
The bq2031 has two primary functions: lead-acid battery charge control and switch-mode power conversion control. Figure 1 is a block diagram of the bq2031. The charge control circuitry is capable of a variety of full-charge detection techniques and supports three different charging algorithms. The Pulse-Width Modulator
Can be lead-acid battery charged using NiMH or NiCd charger?
The charging profile for LiPos is very similar to that for lead acid batteries with the exception of the charge termination and finished voltage levels. If you set your charger to 3 cell LiPo the termination voltage will be 4.2 x 3 = 12.6V. Cutting the charge at this voltage will be too early to achieve full capacity. 13.8V would probably be ideal.
