Re: [FWDLK] Positive ground -= battery charging

[David Homstad <dhomstad@xxxxxxxxxxx>]

Good advice for battery chargers. But when jump starting with another
battery, hook up both red positive cable clamps first. When hooking up the
last black ground jumper cable clamp, it is best to use a ground location
away from the battery. The last connection often makes a spark and this
could explode any hydrogen gas inside the battery. It happened to a friend
of mine once. Luckily, his glasses kept the acid out of his eyes.

Bear in mind that charging a battery can create hydrogen gas, which is
highly explosive.  You're supposed to hook the charge cables up with the
charger unplugged, then plug it in, and do the reverse when taking it off.
And it should be charged in a well-ventilated area.

The safest and best way to charge the car's battery is to
remove it from the vehicle, take it somewhere warm and dry,
clean the battery terminals, and connect an appropriate charger
to the battery. The connection will always be the positive
battery terminal to the positive lead from the battery charger,
and the negative to the negative. The charger will run the
current through the battery "backwards" and this will be converted
to chemical energy stored in the battery until you need it.

Most of the time, we charge the battery without removing it from
the vehicle.

The vehicle controls the charging rate when the vehicle is in
operation by coils of fine wire, or by arrays of diodes. If you
connect a charger and run a large current, or voltage, through
your vehicle's system, damage could result. So, you should
always disconnect at least one of the battery cables from the
battery when you wish to charge the system. This will stop flow
of current to the car's system. re-connect after you are done
with the charging session. I usually unhook at least the ground
terminal when charging.

Use a charger with a six volt setting for vehicle's six volt batteries,
and twelve for twelve. Mix them up and you will overload the battery
or the charger. Lots of heat is usually the first result.

Keep in mind, batteries are dangerous, and can shock, burn, or explode.
It is no fun to explode a container that holds a strong acid.
Wear safety glasses and be careful.

The  +  /// Positive //// red  must always be connected together.  Never
connect positive to negative!   On your positive ground car, the
positive goes to the engine block.  Negative ground cars have the
negative of the battery going to ground on the block.  You never charge
a battery backwards!
