EEVblog - How To Calculate Wasted Battery Capacity

In this tutorial Dave explains how to precisely measure and calculate the remaining (or wasted) energy capacity in a battery using the graphical analysis technique using a spreadsheet. The differences between constant power and constant current loads and when to use them is discussed. Also, the importance of ESR and measuring the battery voltage under load is demonstrated. This is a particularly relevant to the Batteriser product and proof is provided that shows that even over the entire current range, the wasted energy in a battery can be no better than a few 's of percent for a .V cutout voltage. Blowing the batteriser claim of % wasted energy out of the water.
