Can a 12VDC 500ma wall wart trickle charge a car battery or must the voltage >to charge a car battery be greater than 12VDC (like 14 or 15 volts?).
Can a well regulated 12VDC still charge (over a long time) a car battery?
Or must it be over 13.5 volts to (eventually) accomplish full charging?
5. Today's overpriced car batteries cost about $100. Would you
really risk trashing a $100 battery because you don't want to use a
proper battery charger? I wouldn't. Unfortunately, a charger with a
fancy label is not a guarantee of quality. All these chargers were
defective in some manner. They also killed two rather expensive
stationary batteries at a radio site: <http://www.learnbydestroying.com/jeffl/pics/drivel/dead-battery-chargers.jpg>
Spend some time and do some reading on chargers.
6. If you're looking for a "battery maintainer", I suggest you check
what is being offered for boating. They tend to be better built, be
better designed, and unfortunately cost most, than the common
automotive and home user variety. RV and recreational maintainers are
in between.

If you don't like the prices, remind yourself what a new battery might
cost if your charger tries to kill it.

Keep in mind that the Average American:
Does not have a college education, including an Associate Degree (60%).
Does not have a passport (63%).
Speaks one language – badly (74%).
Has never traveled voluntarily more than 200 miles from his/her birthplace (57%).
Has never visited a foreign country, not even Mexico or Canada (71%).
Cannot name the Speaker of the House, even today (82%)
Cannot name the three branches of government (64%)
Cannot read at a college level (83%)
Cannot read for content (54%). This person cannot follow written-only directions.
60% of American Households do not buy any book in a year.
Does not believe in Evolution (42% creationism, 32% evolution, 26% no opinion).
Worst of all: The Average American does not vote. 66.2% of registered voters voted in 2020, a record! However, only 66.7% of eligible voters were actually registered. That means that only 44.2% of eligible voters actually voted.
Pretty abysmal stats.

While I do agree on the buy American sentiment, it's not all that easy
to find an American made tool. And as you see, there is a 3x premium to
get that.

Lots of things wrong here:
1. Common flooded car batteries will not charge using a small trickle charge. You can use a trickle charge to maintain the charge level of
an already charged battery, but you cannot take (for example) a half
charged battery and bring it to full charge with a trickle charger.

Why is that Jeff? Surely any charger that exceeds the self-discharge
current will eventually charge the battery?

No, one of the ones I purchased fairly recently was packaged with an appliance sold at a physical shop in Australia and has seemingly genuine Australian compliance markings on it - it is not some banggood grey

I don't know and I've never seen it explained in print. Someone told
me that many years ago and my experience seems to verify the claim.
When I've tried to charge large lead-acid car batteries which have
been substantially drained (about 50%), with a small "battery
maintainer" or "battery tender", it has usually failed to charge. Not always, just usually. With small lead-acid batteries, it will charge.
I'll eventually be converting the generator starting battery to LiFePO4
plus supercaps. One advantage is that the battery has a very low self-discharge rate. Instead of a battery maintainer, I only need to
fully charge the battery and disconnect the charger. The charge holds
at about 80-85% for many months.

Ok I am not familiar with the situation in Australia, but here in Europe
most equipment is delivered with SMPS wall warts these days, they probably are cheaper as well. And I have done some testing with a power meter
(HOPI) and most of them consume no measurable power when unloaded. That
was the objective of the regulation, so it achieved that goal well.

It could be something as simple as self-discharge being much larger when
a battery has been "substantially drained"...?
Yes, I use LiFePO4 also. Self-discharge is 1-2% per annum, and the
columetric efficiency is very high also (you get back almost all the
charge you put in). Great batteries.

We (the company) decided to design their own fryer timer, instead of

and found optoisolators (4N35s to be precise) that were made and sold by
GE, being an American company. The others that would do what we needed

A well regulated 12 volt supply will not charge a car battery as it 12.6 volts when charged.
It will take a higher voltage than 13 volts to charge a car battery.
Unless precautions are taken just hooking a power supply to a car
battery could damage the power supply especially if it is a regulated
one.
