My 40 year old steel case 6 amp automotive battery charger finally died.
I only want to replace it (and I don't want a contraption that jumps cars).

I just want a new 120VAC simple sturdy 12VDC automotive car battery
charger.
And I don't get out to the stores much lately.

Mine had an analog meter, and a 6V/12V switch (which I never used at 6V).
If they still come with an analog amperage needle, that would be nice.

Any advice where to get a good simple sturdy 12VDC battery charger online?
Here is Amazon least expensive charger with meter

https://www.amazon.com/Automotive-Ba...dp/B07NVHBPDV/

URL says motorcycle but it's also for autos. 5 amp w/digital meter for
more than just amps

If he wants something that's low amp, that's the kind of thing I would get,
ie a charger/maintainer that you can leave on to keep unused batteries
fully charged, eg over winter. The other choice is a higher amp one that
is more useful for quickly charging a dead battery, getting a car going, etc.
I have an old sears one that does 2A/10A/50A, the latter is short term to
start. IDK if there are higher amp ones like that which can also be left
on indefinitely and have the functionality to safely maintain, thought there
is no reason they could not.

If you want a charger that can be left on indefinitely then you need one
that is capable of trickle charging. The one you have is *capable* of
trickle charging on the lowest setting and a normal charge is the mid
setting. The high setting should never be used to charge a battery if
you want a good life from it.

i don't see anything that indicates the old charger he has is suitable to
be left on a battery indefinitely. He doesn't even say it's trickle charge
capable. Trickle charge ones that just continually applied a small
charging current have been replaced starting decades ago with
smart chargers that monitor the battery and only apply a small charge
to refresh it when needed, eg the Battery Tender products.
