buy into what???? Slow charging batteries has always been better than
a quick charge.. Most cars alternators run 70-110amps.. Battery
chargers on a slow charge are only 2-5 amps. Some a bit higher for a
faster charge, but the lower the amps the longer it takes to charge
and the better your battery will be.

**********
Your statement about if you let the alternator charge the battery, you
will never reach full charge.. Define full charge,maybe. Alternators
have the ability to charge the battery, assuming the battery and charge
system are okay, and to maintain it at optimum charge.

Slow charging IS better than fast charging, but it's not because the
charge is "incomplete" in any way. It's because of the heating effects.

Monza,

do you have any idea how many Amps a 70 -110 Amp alternator actually
puts into a battery that is already charged?

since the charging voltage is limited to appx 13.5 to 14.5 in most
applications, almost none. Also realize the same charging systems are on
over the road and farm tractors that can run for days without shutting off,
and supprise, they don`t overcharge the bat. KB

it certainly doesn't trickle charge it.... depends on the accessories
that are on and how low the battery is the more dead you batter is the
more amps it'll use. Slow charging (off of the car) is still much
better than letting your alternator do it.

From Edmunds.com

Here are a few tips to quickly restore a battery using this method.

1. Drive at a constant speed (highway driving) versus stop-and go
(city driving). This will give the alternator an opportunity to charge
more evenly.
2. Turn off all accessories (radio, air conditioner, etc.).
3. If possible, drive during the day. Even headlights use power.
Having them off increases the amount of electricity going to the
battery.

Remember, this does not replace charging the battery. A car's
alternator is not designed to fully restore a depleted battery, but
rather to maintain a healthy one. As soon as possible, put your
battery on a battery charger such as the Battery Tender, and a give it
a full charge for a day or two.

"even" headlights? they're power hogs, close to 10A - more if you have
four headlights on high beam

With a healthy charging system and battery, you should almost \
NEVER have to resort to the use of an external battery charger.

The alternator will bring a good battery up to the charge level
it can take.

I dont really care what Edmunds said.

If you have a car/truck, a good battery charger is handy to have in case
you ever need to use it.No legitimate reason is needed.
