I use a stove top expresso maker. Great coffee. ZERO electrical need or use.

There you go,that calculates at 12V to 27.08 amp hours for a good cup of coffee..LOL..So the ops 100AH battery would certainly do it..
OK and you are drawing at the one hour rate so the battery capacity is only 50 AH. The 27 AH is over half the capacity and we assume the battery was fully tip top charged before starting the brew.

Yes might do in a pinch.

OP said he has budget issues. Suggesting a Jackery at $1000 isn’t an option for him. Then he needs to breakout his generator...to recharge the Jackery. Usable Jackery amps is about 70.

I didn't want to go into the dreaded 50% rule everyone is aware of..By the way,I read an article on that and it said,if you draw your battery down to 20% all the time,you will only lose 6%of your life span..Interesting,I thought.

time2roll,

SiO2 do not exhibit much voltage drop. They are more capable at high current draws than Li, from what I've been able to read.

I heard from one company who told me that after the 2800 cycles, 80% of OEM capacity still remains. I'll plan on that when I replace the jars and probably go for six in two equal banks of 3 each, wired in a balanced manner.

I assume the OP has a flooded group 27 from WalMart.
Yes various upgrades can be made. The OP seems to be limiting his circumstances to the existing single battery. That is the basis of my posts here.

The op stated, he just bought a $400 Lifeline battery.

Which is way too much. Perhaps he has a higher AH battery.

I was recently at the beach on a rainy day in the morning and my wife wanted a cup of coffee I had to run out and start the generator in the sand and rain that's the only reason I want an inverter. LOL


Enjoy my fun, 27-second coffee video.

It's just Mrs. SpeakEasy and me now (empty-nesters). But we can choose from among 7 grandchildren to drag along with us!
