it's not acid... it is corrosion and oxidizers
Battery acid does not build up, there is a fixed amount. Provided the battery is kept topped up with pure (distilled) water to replace any lost gases during charging, it should last a few years. There should be no battery acid in the engine. The engine needs battery power only for starting.
No, it is battery acid corrosion caused by leaking fumes. Clean it off with water and baking soda which will neutralize the acid.
Car battery acid consists of Hydrochloric acid and Sulphuric acid.
On a car battery, the cables attach to two metal posts which stick up on the top of the battery.
your battery terminals may have battery acid build up between the terminals and battery posts, remove both terminals and clean with boiling water refit terminals and try to start again...same thing happened to me once...
You can hook the battery charger to the battery in the trunk, or to the jump start posts under the hood.

It is not recommended to install a lead acid battery of any kind in an enclosed space. Noxious and flammable gases can sometimes build up in those situations.
YesYes
acid erosion, citrus acid, sugar, build up of plaque
You will die.
Remove the positive terminal on the battery for 20-30 minutes and then replace the terminal on the battery and tighten the bolt very well. Also, for battery acid build-up on the terminals, pour several cups of boiling water over the battery terminals.
