12V Deep Cycle battery with Pure Sinewave inverter for tube amp?

Recently I purchased the largest 12v deep cycle battery that I could find. I also purchased a small 500 watt pure sine inverter. After connecting my El34 Single Ended to the inverter, the results were incredible. I was just curious what the community thought about this idea, comparitively to power conditioners and what not.

I believe DC power is going to sound better than any AC with or without a power conditioner. Basic problems have been the length of play time and the length of charging time. What are you experiencing?

Put about 2 hours into my listening session last night. Connected battery to charge up this morning, and was still at 97%. Its a small amp, and is only pulling about 150 watts. Would not be feasible for more powerful amplifiers.

It all starts at the wall. If you can eliminate the wall, so much the better.

If you want to run more might want to look into batteries from a used Tesla. They say the spontaneous combustion risk is low.

Be careful handling lead acid deep cycle batteries! Hydrogen gasses and fumes emitted during charging is both an irritant and potentially explosive so ventilate the battery and area well at all times.

@imhififan should I be worried during discharge(connected to inverter while powering amp)? I will be doing all charging of the battery outside in a ventilated area.
