The YellowTop D34/78 is Optima's dual-purpose battery: it starts engines and handles repeated deep discharges, which is why it turns up in off-road rigs, car audio builds and vehicles with heavy electrical loads. Its spiral-wound absorbed glass mat design is sealed, spill-proof and vibration resistant, so it can be mounted in odd positions and survives rough terrain better than a flooded battery. It is a Group 34 size with top and side terminals, so it drops into many GM and Chrysler applications and most custom trays. Compared with a plain starting battery it costs more and delivers less cranking reserve per dollar, but it recovers from deep drains that would ruin an ordinary battery.
