I wonder if my (EV, lithium) car weighs more when the battery is charged up.
There are no "tailpipe emissions", so it must weight the same? :-)
A lead acid battery "uses up" water however.

And when it dies, its spirit goes up to heaven. So you need to weigh it very carefully just before it dies, and again just after. Then you will now how heavy the battery's spirit was.
Lead acid only loses water when over charged. Sealed lead acid is 'sealed'
Charging any battery is only effecting a chemical change
Blimey, we will have the van full of budgies next.

No. It gets ever-so-slightly heavier. You can work out how much with the capacity and E=MC^2.
On the other hand it's probably less than the fly on the windscreen :)
Again, no. It converts chemicals between states, all the same atoms are in there when it is flat as when it is charged.

of course.
E=MC^2
it would be at least a couple of micrograms heavier.
Found this on the topic. Seems that process is even yet not fully understood.

Isn't the phrase "valve regulated lead acid"?
If you mean a so called sealed car battery, they're not. They all have a vent somewhere. They have a clever design which traps 'moisture' given off and returns it to the electrolyte. In practice, with a decent charging system they don't need topping up in their lifetime.
Without that clever design of trap, they would need topping up with distilled water - same as they all once did.
Yup, and AGM, absorbed glass mat
