If this tester applies only a 100 amp load, can it properly test systems where the starter draws around 200 amps, as on larger engines?

1. Yes- this tester is meant for automotive batteries. The scale is calibrated for the 100 amp load the tester puts on the battery for the 10 second test period. If it applied a 200 amp load, the scale would have to be recalibrated. A given batteries state of health would be good or bad no matter whether a 100, 200 or 300+ amp load was applied to it for a 10 second period.
After testing it would be a good idea to put the battery on a float or trickle charger until it is fully charged. Car battery life is greatly extended if kept fully charged and not allowed to sit around partially charged.
1. No, do NOT use this tester on a tiny battery with only 4 aH capacity. This tester is meant for automobile and truck batteries. They typically have aH capacity of 30 and more amp hours. Using this tester on a small non-car battery would be like putting a direct short across the battery terminals. It is potentially dangerous and you could ruin your battery.
