if you discharge below 10.5 v you will hurt batt.
ell. A 12 volt lead acid battery has 6 cells and must not be discharged below 10.5 volts (6 x 1.75 = 10.5). If these batteries are discharged below this, they will most likely be damaged.

How to get a lead acid battery to last a theoretically infinite amount of charge/discharge cycles. This is what the battery companies have kept secret from you for over 80 years! You'll also learn the Art & Science of Nursing Dead Batteries Back to Life!

for what its worth you my not see sulfation at first if the batt loses capacity its getting sulfated
i dont know if a converted batt will desulfate

cool i had a toy like that
i just saying boil water is not a good way of determining the energy [heat] in it /for 99.9 of the people it is. but us it not

i maybe way off but but boiling water in denver a mile high has less energy in it it will take longer more heat to cook a egg, than at sea level
water boiling is not a good ref. point [4 me] i dont think water will be made safe when boiled at 200,000 feet the heat is not there
you got my att. because i worked all time with a 2 lbs neg.pressure fixing fuel leaks on large aircraft
water boiling above sea level is not a good indication of the the energy 4 ME in it ,unless pressure is considered
i need to read some more [cold boil ] cold steam?
i sure that if pulling a vacuum on a boiler gave the same energy as an open boiler it would all over the place
yould easily get more power out of steam for a lot less in put heat, the way i see you actual make it harder to put heat in
Choosing partial vacuum distillation over atmospheric is not aimed to save some energy, but for other reasons as maintaining a lower temperature; of when the temperature of the heat resource is low.
Then, to distill seawater, the 'energy price to pay' for the task is not decreased by the lower temperature-partial vacuum technique.
I will have to evacuate a certain volume in order to allow the water to boil and fill that space, and it will stop when the pressure reaches the vapor pressure.
Air Watts
Central Vacuums in North America are measured by CFM and waterlift.
so keep the vacuum on the water is what will kill the energy saved by lower temp and lower boil point
due to lower air pressure [i think] ?

Hi all. A litre of water at 25℃ needs a certain amount of calories to become steam at 100℃ ∆t=75℃ (75Kcal + 540Kcal =615Kcal) if I remember the figures. That is a 1 ATM. Under partial vacuum, such energy requierement can be less. Let's say it boils at 45℃ under such partial vacuum ; ∆t=20℃ thus w...
