How to check voltage of battery
WebThe technique is to measure the voltage across high potential battery first, than against the lower ones and negating the subsequent batteries voltage from the one at higher potential. For example for the above circuit the measured voltage across battery-1 is 48v and battery-2 is 36v. Negating 48v-36v=12v gives us battery-1 voltage. WebWe are setting up a multimeter, along with the battery, to test. We will use a 9-volt transistor battery for this guide. Step 1: First, we will measure the voltage of the battery. Second, …

When the Magsafe connector is plugged into the Mac, the Mac applies a resistive load (e.g. 39.41KΩ), pulling the power input low to about 1.7 volts. The charger detects the power input has been pulled low, but not too low.
WebInsert the pointed tip of the red test lead first in one hole and then in the other. If you read 12-volts to ground on one end but not the other, the fuse is blown and needs to be replaced.
