Does anyone leave their amp and preamp on all the time?

Do batteries need to warm up? Do they break in? Just curious. Is the break-in time longer than the battery life? I use graphene contact enhancer on my Walkman batteries. Is that wrong?

No, they go to standby or I turn them off. 

Wow, someone bought into the climate change hoax big time! It’s all made up BS! You have been duped by Greta apparently. The earth has been here for billions of years, I think it will survive a few hundred of the industrial revolution. People are soooo gullible, it’s a freaking money grab period! The earth goes thru warming and cooling cycles and has since the beginning of time ......there Is absolutely no scientific evidence that any of this $h&t is true, none....In fact 99 % of scientists agree there is no freakin crisis my god.....its the new religion is all it is. Come back to Jesus Christ and be happy...its laughable really....get rid of fossil fuels? And use what? Electric cars? Hahahaha where does most of the electricity come from to charge the car? You guessed it fossil fuel....why? Because it is plentiful and reliable and it works.....wind power, not always windy. Solar? Too expensive and well not every day is sunny....these people are insane moonbat liberals sitting on piles of cash with nothing else to occupy their time except to go out of their way to make normal , rational, logical thinking people miserable. Ludicrous...

Yeah, one flight in their private jet instead of flying commercial and they have polluted more than I will in a hundred years of leaving my equipment on. They also typically own several gas guzzlers by way of automobiles,  SUV’s and or super sports cars not to mention pools, jacuzzis, and lawn sprinkler systems.
