A recent answer at a sister site suggested disconnecting the battery routinely.
I often disconnect my battery before embarking on a hike. Especially if I am in a remote location. This is a nice way to ensure there is no slow electrical drain that may discharge the battery. Additionally, it would hamper a would-be thief’s efforts at stealing the car.
Back in the old days, when my vehicles were built in the 1960s and 70s I would usually instal a 'marine battery terminal connector' to make it easier to connect and disconnect the battery, for very similar reasons as the OP in quote above.
But today my vehicles are made in 2010s and have significant on board electronics. I know the drivers door can be unlocked with a key when the battery is dead, and the inside hood release will also work. Functionally this is potential possible, but are there any negative side effects from disconnecting the battery routinely?
Related questions, that don't seem to address this:
- When should I disconnect the battery to stay safe during repairs?
- How should I prevent my battery going flat when I leave my car alone for a month?
- Does disconnecting the battery reset on-board memory?
Note In the 60s and 70s, this was not a good anti-theft solution, opening the hood, and using a wire and screwdriver where all that was required to start the car. At this point the thief would just connect the battery. Hidden disablement switches were the inexpensive deterrent of choice.
