This means that, for a typical 10 Ah battery with a Peukert constant of 1.2, a 10 A discharge rate will discharge the battery in just 0.63 hours or 63 per cent of the expected time. Note that Peukert''s equation holds true for other types of cell technology, but the Peukert''s constant must be known for the cell type and age.
Many DC-DC load requirements can be met by DC-DC converter ICs that include integral power switches. Most such ICs include MOSFETs, but some employ bipolar transistors. The load current capability of newer internal MOSFET DC-DC ICs can handle up to 25A (e.g., the MAX8655 and MAX8686 ).
