I noticed that too. Question is - does it hurt to overfill them?If you think that the filler caps are funky then try to fill it with distilled water, which is even more difficult since the level is not easily visible.

well, the battery levels were low ! had to put 8oz
of distilled water in total for all cells ! Got it filled
to high mark as best as I could tell... it was easier to
shine light into hole and gauge height of level
from top than from the outside... maybe need
brighter light..
I wouldn’t try to remove any excessive electrolyte if I ovetfilled the cell. If you do, you actually reduced the acid content of the electrolyte which isn’t a good practice. Just like you don’t add acid when the electrolyte level is low as doing so will increase the acid content which isn’t good for the chemical reaction. Only water in the electrolyte evaporates.I believe so, they have a max level to account for expansion of the fluid during use. If you do happen to overfill, you can use a turkey baster or other similar syringe to remove the excess - just be sure to clean it well or throw it away afterwards.
depends on the climate as well. Where I am its very hot most of the year. The level goes below min in about 2 to 3 yrs and I suspect that is why the bbatteries die here fast. A reason I now have real AGM and removed the oem. Dont want to mess with liquids anymore. Had my fare share in the past. With that said in other places I lived up north where it rarely got hot, after 3 yrs the level has not went down much and I could get 5-6 yrs easily out of a battery.I'm still on the original OEM battery in my 2016.5 CX. Never had an issue, or even a hint of an issue, and I've never checked the water levels in the cells. I guess I'm going to have to check em now after this thread. I guess I had better check the MX too while I'm at it.
Yes my youngest daughter lives in Texas it seems they are real lucky if they can get a battery to last much longer than 3.5 years.depends on the climate as well.

Driving the car longer time (not distance) and state of charge of the battery also plays a big role.

I couldn't get a reading no way, no how. I tried it in the garage, outside on a partly sunny day, with the flashlight behind the battery and without the flashlight. When shining a flashlight into a plug hole the level is hard to discern.the battery side cover (the black plastic) has 2 openings. One that is visible from the engine side and one from the rear. The case of the battery is translucent. Put a flashlight from the rear and check then level from the side.
Sealed batteries have around for long time. You may not have had to top up a battery because the ones you had were sealed. I cannot recall the last time I had a battery that wasn't sealed, OEM or aftermarket, maybe the OEM in my 1996 JXi, or my 1988 Camry before that.It’s funny. I’ve changed every type of automotive fluid I can think off, yet have never (in 30 years of driving) never added water to my car battery.
Clearly, it’s a “me” issue and something I probably SHOULD be doing…
Not all sealed batteries are maintenance free and doesn't mean they're not vented. Quite a few of them you can "unseal" just by removing the label and prying off the caps.Sealed batteries have around for long time.

Well, just because it is possible doesn't mean it is necessary or advisable.Not all sealed batteries are maintenance free and doesn't mean they're not vented. Quite a few of them you can "unseal" just by removing the label and prying off the caps.
They’re connected electrically. Each cell is in its own isolated acid cup. Kind of like the old flashlights with multiple D cells; they connect electrically, but are isolated the chemistry from on the the next (until they leak). Hence a separate filler for each cell. I guess one cell could need filling while the others don’t, but I’ve never seen that in my experience. It’s always been if one’s low, so are the others.Are the cells in these batteries connected? And if so, why six plugs?
And they usually are at different level below the full line.⋯

... if a cell is degraded, then it might have lower electrolyte than others.I guess one cell could need filling while the others don’t, but I’ve never seen that in my experience. It’s always been if one’s low, so are the others.
