2016 Toyota Prius | Why is your Battery Draining? Find Parasitic Draw!

Once again this is one of my latest endeavors. When you own “things” they tend to break at some point. So one of my cars would drain after about a week or so of sitting. Pretty annoying. Killed one battery so I replaced it, then the new battery died. Eventually got that battery replaced as well. Then guess what?? Same thing, it died. Went down to about 4 Volts and I decided to take matters into my own hands. Brought a trickle charger to bring life back into the battery then set out to find the parasitic draw. In order to check for a draw you need a fully charged battery to efficiently check. Battery charged over night then the next day check fuses and relays and luckily found my issue. So removed the offending fuse and also the drain on my battery.
