Why does my Honda CRV battery drain so fast?
I then started going through the fuses under the bonnet and when I removed the ‘BACKUP’ Fuse the drain dropped to around 17mA.

Why does my Honda Civic battery keep dying?
All my issues were resolved and my battery stopped dying. The bad cell in my battery was causing the battery to discharge/spark on my negative terminal and connecting wires, and this led us to believe it was a parasitic drain. However it ended up being a relatively simple fix and obviously a little pricey.
