Abstract
A system for testing a battery includes a first capacitor and a second capacitor. The first capacitor and the second capacitor are configured to be arranged in series in a first arrangement and in parallel in a second arrangement. The first capacitor and the second capacitor may be cycled between the first arrangement and the second arrangement to characterize a response of a battery.

A system for testing a battery comprising:
- a battery tester electrically coupled to a battery;
- a first capacitor electrically coupled to the battery;
- and
- a second capacitor electrically coupled to the battery;
- wherein the first capacitor and the second capacitor are configured to be arranged in series in a first arrangement to charge the battery;
- wherein the first capacitor and the second capacitor are configured to be arranged in parallel in a second arrangement to discharge the battery into the first capacitor and the second capacitor;
- wherein the battery tester is configured to characterize a response of the battery to the first capacitor and second capacitor being switched between the first arrangement and the second arrangement.

A system for testing a battery comprising:
- a battery tester electrically coupled to a battery;
- a first group of capacitors electrically coupled to the battery;
- and
- a second group of capacitors electrically coupled to the battery;
- wherein the first group of capacitors and the second group of capacitors may be selectively switched between a first configuration in which the first group of capacitors and the second group of capacitors are in series with each other to charge the battery and a second configuration in which the first group of capacitors and the second group of capacitors are in parallel with each other to allow the battery to discharge into the capacitors;
- and
- wherein the battery tester is configured to characterize features of the battery in response to the selective switching.
