Battery. During winter storage
What if I disconnected both battery terminals and install two adapters one for each terminal and hook my battery tender up to the adapters so they will charge the battery go in the winter time and stop the electrical system I’m drawing on the battery constantly hi battery charger does shut down on the battery is fully charged the question is well this scenario cause any problems with electrical system in the car I have a 1984 Corvette 0 ideals how do I do appreciate Hope to hear from someone this is just a thought usually I just keep the battery tender to the battery and feed the system all would you long knowing that the electrical system is constantly drying on the battery

1000's of us do it every winter

Just to add, Battery Tender (specifically) is NOT a "trickle charger", but rather a processor controlled device with a programmed algorithm specifically designed to periodically pulse the battery to prevent the development of sulfate formation. (Lead sulfate is a crystalline, non-conductive structure that as it forms and spreads over the lead plates effectively reduces the area exposed to the electrolyte. This effectively reduces the current (amperage) the battery can produce; effectively increasing the internal resistance of the battery. Periodically pulsing the battery with a higher than normal charging voltage spikes will remove sulfate w/o boiling the electrolyte away. I personally have experienced batteries that have lasted over 12 years and still spin our Vette starters like new!)

Just curious, it was stated that the Batttery Tender has a means of reducing sulfate in the battery. I can not find anything that says Battery Tender or Battery Tender Jr has a desulfation mode. I have two Battery Tender Jr's., so I have looked for that info.
I also have some Schumacher SpeedCharge maintainers and they state they have a desulfation process built into them.
If the battery is in good shape, any good maintainer should be fine, but if the battery condition has deteriorated I think having a desulfation mode would be good. In practice, I used one of the Schumacher maintainers and it seemed to bring a bad battery back to life for another year. It didn't make it like new, but it helped and I got another year out of that battery.
Does anybody have more info on which maintainers have desulfation modes or do not have them.
