If you run electric vehicles, you probably have several battery packs to keep track of, and you want to be sure that the pack you just installed is charged. Wrap a rubber band around your packs. When you remove a fully charged pack from the charger, tuck the plug under the rubber band. You will remove it from the rubber band to install it in the vehicle, so leave it that way once you’ve remove the dead pack from the vehicle.
