Let's start with my scooter. I buy new batteries for scooters like
buying cough drops for a sore throat. Why? Because
conventional charging results in an eventual meltdown of
all of those beautifully constructed plates.
I have come back to see if my battery is charged only to
find the outside cases melted together on a hot day and
an over chagre.
Now does that tick me off? You bet.
No ALUM won't make your battery last up to 6 times
longer using a DC charger, nope.
The only thing that makes a battery last 6 times longer
is to COLD BOIL your batteries EVERY SINGLE TIME.
Cold boiling refers to a boiling action inside a charging
battery that is generally associated with heat and is
bubbling away stone cold.
This bubbling action becomes more distinctive at the end
of the charging cycle and signals a full condition. The full
condition of a cold boiled battery is as much as 20 percent
more than a DC charge.
The heating action of DC is the first thing that kills your battery.
The second thing that lowers your battery life is caused when DC
chargers can never fully charge a hot plate, then sulfates spiderweb
your plates.
ALUM makes batteries HIGH DENSITY batteries taking almost twice
as many joules to charge them because these ALUM batteries
give back more.
Thinking that ALUM conversion will extend battery life
without the use of an ENERGIZER is a false assumption.
You can extend the life of an ACID battery 6 times with an
ENERGIZER. The Alum batteries have qualities that far exceed
LEAD ACID.
The ALUM batteries I have tested using an inverter will start
at 12.5 volts and when they reach 11.5v with hang there
nearly forever then go all of the way down to 10 volts
under full current.
My lead acid cells start at 12.5v and when they go down
to 11.5 volts you can look for a full crash landing in a very
short time at 10.7 volts.
ALUM is a battery improvement but can never be exchanged
for an ENERGIZER.
My Energizers have 3 modes of operation. SG mode which is
seldom used directly connected to the battery. Instead the
SG mode charges caps that are dumped to the battery.
When I do not use a capacitor discharging unit, I use what is
called GENERATOR MODE or JOULE THIEF MODE. This means
that the batteries share a common ground unlike SG mode.
I use GENERATOR MODE to cold boil my batteries because
the pulses relieve the heating condition that DC chargers
impose.
Also remember that an ENERGIZER can be used to force
charge a battery that can cause heating. This is why
following manufacturer specifications is important.Such
as the C20 format.
A 20 AH battery C20 rate = 20 divided by 20 = 1 amp
Also remember a 20ah battery is only good for about 2/3rd
of 20ah = 13ah because we don't want to take all of the
power from the battery.
So a 20ah battery needs 20 hours to charge and 20 hours
of discharge time to get the full 13ah of power from it.
If you run the battery harder than this heating occurs and
shortens the life of the battery as well.
