I haven't seen one in a long, long time. Maybe in OEM batteries, but I don't think the last two I've replaced had them.

It only checked one cell. You need something more than the state of one cell.

It was mostly for the dealer to use when evaluating the battery for warranty.

Eye dry : replace
Green ball sunk : charge, then load test
Green ball floating : OK to load test now

Also it looks like an advanced high-tech feature to the consumer.

To lower costs kind of like most brake pads have eliminated wear indicators as they cost 2 cents per indicator. Why not stuff our pockets with the savings instead of putting those on. They can tell when the backing plate is grinding the rotor. it's all about profit and need.

I currently work with several OEM car manufacturers and it amazes me how much they need something until you tell them how much they can save by removing or eliminating it. You can't get rid of it fast enough then.

Right. Like for example, the state of no cells, and a new battery.

They have went the way of the auto cassette player a long time ago, didn't they?

I only recall seeing them on Delco batteries. Did anyone else ever use them?

I recall depending upon the green eye on the first ever no-maintenance battery that I had in a car. What a disappointment. I quickly learned that there was no such thing as a no-maintenance battery, at least as far as lead-acid batteries are concerned.

All good guesses guys, but the real reason they got rid of the eye is because the battery beancounters determined too many people were noticing the eye was bad before the warranty expired, driving up free replacements. Eliminate the eye, and there's no way to know the battery is on its way out until it doesn't start your car, 4 days after the warranty expired. $100+ for your "pro-rated" coverage, ka-ching!

Ask me how I know....

this. You may have 5 bad cells but the one with the eye is ok.

Johnson Controls can still make one if specified by the OEM. I found this photo from this thread:

https://bobistheoilguy.com/forums/ubbthreads.php/topics/3368999/2012_Honda_Civic_Battery



I can't read it too well, but the OP in that topic says the date code on the battery is 01/2012. I can make out that's it's Johnson Controls even though it's kind of low resolution. It certainly looks like a JCI battery.

My wife's 2011 Mustang factory Motocraft battery had the eye.

I replaced it with a Bosch AGM.
