NO! never remove the acid caps! EVER!
only if it is a battery to something like an ATV or dirt bike you would take the acids caps off and only to refill the acid.
if it is a normal car battery just leave them on.
if you are talking about the (+) and (-) battery TERMINAL caps then on some vehicles you have to take them off so that the charger can come in contact with the battery posts.

Do you take the fill caps on your battery off when you charge it at the rate of 2 amps?
no way.
Why is it important to replace the bearing caps in their original position?
Con rod and big end bearing caps are line bored at the manufacturing stage. Replacing the caps in the original positions keeps the caps in line to the original machining. By mixing the caps, you could well run the risk of running the bearings inside the caps
What are bearing caps?
You have rod bearing caps that hold the rods on the crankshaft. And you also have main bearing caps that hold the crankshaft in the engine block. NEUTZ.
What is the reservoir that holds the greatest amount of water?
Ice caps/glaciers
Where is most of the solid water on earth?
glaciers and polar ice caps
About four week ago you replaced an old battery that was leaking acid Now your new battery is leaking acid is it just a bad battery or could something else be causing the new battery to leak?
Leaking from where on the battery, the caps? If so the charging system may be over charging the battery and causing the acid to boil out. Could be a voltage regulator problem.
How do you charge 12 volt battery with caps on or off?
All lead acid batteries are always charged with the caps on. What this prevents is the acid accidentally boiling up an out of the cell and doing damage to surrounding equipment. When a car battery in a vehicle is charging when the engine is turning over, the caps remain on. This procedure should be no difference when the battery is on a plug in battery charger, the caps remain on. There are vent holes in the caps which allow any built up pressures to release.
How do you know if a car battery is not sealed?
it will have caps on it that you can remove.
How do you open a car battery?
If it is a sealed battery you do not open it. If it is not a sealed battery simple remove the caps.
Can you store a 12v battery on the ground?
yes but they should not be left out in cold weather and keep them away from any heat source or sparks like from welding etc if charging the battery the acid caps should be loosened to allow excess gas vent
What batteries has removeable vent caps?
Lead-acid batteries have. The cap is not only a 'vent' to release gas during charging, but also a means of adding water to a cell when the plates aren't totally submerged.
When charging your battery the water boils out of the cells before it is fully charged The cell caps are loosened to vent and cells are not over filled?
Try charging at a lower rate of amperage, also check condition of battery with a battery tester, under a load.
Can you add acid to an ATV battery?
No, but you can add distilled water if it has filler caps and it is low of electrolite. Do not add tap water or acid.
How do you add water to a Yamaha 125 Atv battery?
If it is a sealed battery you cannot. If it has fill caps, then remove the caps and fill each cell to the full mark with distilled water.
Will a dead battery leak acid a shortan lifespan?
Anytime you run an automobile battery down you shorten the life of that battery. An acid leak in a sealed battery means the battery must be replaced. If it is leaking from a battery in a battery with filler caps just add distilled water to the full mark and wash the acid off the vehicle battery compartment.
How do you check car battery fluid level?
If the battery has removable caps: Remove the caps and add distilled water as needed to cover the plates with 1/4" of electrolyte. Or fill to the bottom of the "split" ring is battery is so equipped.
Do leave caps off or on when charging battery?
By all means, wear a hat. The battery should wear its caps as well.ANS2:The battery needs to be able to breathe. If you know for a fact that the caps are clean and the vents are open you should leave the caps on. Back in the day, when the caps screwed in and had little tiny vent holes, that was a good idea to leave the caps off or loose because the battery could build pressure enough to blow out the side.The vent caps, today, will pop off before the battery case blows out. If you leave the caps on, you are going to retain a large volume of explosive hydrogen gas if you don't top the cells up with distilled water beforehand. That hydrogen can be ignited by any nearby sparks.
