A 12 volt automotive battery system 12 includes a first battery 30 coupled to an electrical system 66, in which the first battery 30 include a first battery chemistry, and a second battery 32 coupled in parallel with the first battery 30 and selectively coupled to the electrical system 66 via a first switch 288, in which the second battery 32 includes a second battery chemistry that has a higher coulombic efficiency than the first battery chemistry. The first switch 288 couples the second battery 32 to the electrical system 66 during regenerative braking to enable the second battery 32 to capture a majority of the power generated during regenerative braking. The 12 volt automotive battery system 12 further includes a variable voltage alternator 64 that outputs a first voltage during regenerative braking to charge the second battery 32 and a second voltage otherwise, in which the first voltage is higher than the second voltage.
