Battery Water Level
 

My FR-S was manufactured on 12/12 and I don't think the battery water has been checked (if it was) since then.

For the old fucks like me here checking and adding water to a car battery is nothing new but this maybe helpful to some forum members.

If you still have the original battery it has Lower and Upper level markings on the front of it. You should fill the cells with distilled water to just below or to the bottom of the cell tubes. The bottom of the cell tubes is about at the Upper level marking. Wear rubber gloves and safety glasses.

Water levels were low, just above the lead plates.

Upper and Lower level indicators

Added water to just below the cell tube bottoms

Use a small paper cup or syringe to add water to the cells

I'm guessing this is one of the reasons people like to upgrade to the expensive AGM batteries from people like Optima and there Red top stuff

Oh yes, and ....... after you get finished messing with the battery, DON'T wipe your hands on your pants ........:eyebulge:

Or scratch your nose or other body parts with your gloves on!!

So I was just checking my oil level and wanted to check the battery level on my13 that was purchased fall of 2013.. I literally couldn't find a water level! So I'm guessing this means it's completely full? Thanks for your help

Anyone know if you can check/top off the level on Napa brand batteries?

Yes you can. Follow this wikihow. http://www.wikihow.com/Check-Car-Battery-Water-Levels

NOTE:
It is important not to fill it above the upper level marker. Like all indicated limits there is an upper marker for a reason. If you overfill you run the risk of it overflowing when put the caps back on or when the battery heats up and the acid expands. It will mess things up!

I just topped of my battery, I can't believe I've put it off for so long! Had weak starts, felt like this was going to be the breaking point so ran to autozone to get a battery filler tool. Leaving autozone the car barely turned over! Drove home, added a miniscule amount of water to each hole because I didn't do any scientific measuring because i was parked on an incline. Car started up immediately after that!

Check and make sure the battery is not hot when you do this. Also check to make sure the battery is not bloated. Unscrew slowly, if you see/hear that there is some gas releasing as you unscrew, let that pressure bleed off slowly.

What do you get by doing this? I normally can get 7 yrs out of my batteries. Will doing this extend its life to 10?

If you don't have to add any water, you get peace of mind.

If you do have to add water, you restore the proper concentration of sulfuric acid in your electrolyte.

"Low maintenance" is not "no maintenance." Not checking it is a crap shoot. You've been lucky.

I keep an eye on the original battery acid level and after 4 years topped it up with distilled water.
The battery is still going strong.
Don't use tap water, it will destroy the battery!

I thought the caps on most lead acid batteries had a breather hole ......:iono:
