Frequently asked questions
What makes your battery charger better?
Save A Battery is better because its a small, powerful and
stronger than most small transportable charging units. Secondly,
it maintains and rejuvenates a battery, the longer it's connected,
the better the battey gets, its that simple. It has a Load
Tester built-in that can be used to test the battery and cycle
a weak battery back to health. Thirdly, it has a built-in
diagnostic voltmeter so that tests on all 12 volt electrical
components can be performed.
Why are your cables different?
Since there are so many different ways a battery charger can
be used, we designed versatility into our units. Our Modular
Cables System allows for cables with multiple functions to
be used through the same port. The gold contacts improve reliability
and work better in harsh environments. We offer seven different
types of battery connections. Alligator Clip-on, Cigarette
Lighter, Battery 5 amp LUG, Extension DC and AC and Voltproble.
The bright yellow cable color is to aid in seeing the cable
on the ground to avoid accidental unplugs. Our unique cable
end mounting loops make it easy to tie down the cables perfectly
in place, with no dangling.
How do you mount your chargers?
They can be mounted on the wall, placed on the ground or mounted
in the vehicle and cables. The unique mounting bracket is
easy to install and allows the charger to be removed and used
How does the Maintainer work?
Our microprocessor controlled circuitry is smart, it knows
what to do and adjusts the charger to do the right thing.
When the charger is plugged in it immediately goes out and
looks at the battery. If it finds a problem the charger will
let you know. It wont turn on, it wont short circuit, it wont
hurt the battery. It will simply light up the fault light
on the front of the charger. When it sees a potentially good
battery it will then go into charge mode and as the battery
is charged, it switches modes until it finally goes into maintenance
mode. Here it will stay, checking, monitoring, rejuvenating
and waiting until it is disconnected. The longer the charger
is on, the longer the battery will live. Its that simple.
Can I really save my battery?
If the battery has not been left in a discharged state for
long periods of time, the answer is yes. This is what makes
us different from the competetion... after the battery is
connected to a charger the sulfinated plates can actually
confuse a regular charger into believing the battery is charged
when it really is not. When you try and use the battery it
simply doesn't have the strength to work properly. Our approach
to bringing a battery back to life is by using our unique
Load Test circuit and actually cycling the battery between
the fully charged state and a completely safe but discharged
state. The process is simple, charge the battery, then turn
on the load test and low voltage alarm switches. The load
tester will slowly drain the voltage down until the alarm
sounds and you simply flip the load switch off and it will
charge the battery back up to full. Repeating this process
is called "Deep Cycling" and it will get your battery
back to health. Most good batteries of average size will last
days before the alarm sounds, but a weak battery will sound
in minutes or hours. The cycling between the two states of
charged and safe discharged with the pulse circuitry built
into our charger
will rejuvenate most batteries after 5 or 6 cycles.
Can I use the charger without plugging it into the wall?
An impressive and unique feature of the All-In-One and Tester
models is the ability to monitor any battery for low voltage
without actually having to plug it in to the AC outlet. By
simply connecting the unit to a battery, the low voltage alarm
that is built-in will sound an alarm when the battery needs
to be recharged. Connecting these units will never result
in damage to the battery because the alarm will notify you
of the low voltage condition well in advance of possible disaster
How is a battery constructed and what makes it work?
Lead Acid Batteries have been around for a long time, the
technology is old but still very effective and affordable.
Batteries will store energy and make it available to you when
needed. This energy however, has to be replenished and maintained
or it will dissipate and your car will not start as well as
shortening your batteries life by a considerable amount. New
cars increase the toll on batteries, with the stereos, alarms,
electronic gadgets, etc. Understanding what's inside will
make things a little clearer as to how to help them live a
What is inside of a battery and what types of batteries
If you were to open up a Lead Acid battery you would find
a large amount of lead plates (and other materials). These
plates are divided in cells, for a 12 volt battery you will
find 6 cells. Each cell produces approximately 2 volts and
are connected together in series, so 2 x 6 = 12. These plates
and cells are surrounded by a bath of sulfuric acid and water.
This solution is called the electrolyte and on some batteries
you can actually remove the cover and see the liquid. Newer
maintenance free batteries do not allow inspection of the
liquid. This electrolyte causes a chemical reaction which
produces electrons and that is what makes the battery work.
(Ok... this is a very simplified answer but actual details
would be a book all to itself). There are a variety of Lead
Acid designs that differ a little, they include Wet Cell,
Gel Cell, and Absorbed Glass Mat (AGM). All of these technologies
are similar but offer additional features and benefits. The
most common is the generic Lead Acid which is offered in two
forms. The first is known as a Cranking Battery and the second
is a Deep Cycle Battery. Basically the Cranking Battery is
used in most vehicles and is designed to provide a large amount
of energy for starting and are usually designed with more
plates. Deep Cycle batteries do not provide this high energy
level but rather they are designed for long term energy needs
and can live with being deeply discharged and recharged many
times. This type of battery is found in RV's, Boats, Golf
Carts, etc. where a smaller extended load is being used.
A fully charged battery that is checked with our tester should
read 12.6 to 12.9 volts. It should also be noted that there
is very little difference in voltage between a fully charged
battery and a dead battery which is about 11 volts. It is
also important to note that a battery that goes below 12.4
volts is already starting the sulfation process and its performance
and longevity will begin to deteriorate. That's why its so
important to keep a charger connected when not in use... to
keep this from happening.
What are the battery ratings and energy scales?
Batteries are rated by the amount of energy they can hold
and their ability to produce current at a determined rate.
The four ratings are AH, RC, CA, and CCA.
- AH... stands for Amp Hour and represents how many
amps can be removed from the battery in how many hours.
In other words a 20 AH battery on a motorcycle will provide
1 amp of power for 20 hours. The larger the AH the larger
and higher the capacity of the battery.
- RC... stands for Reserve Capacity and isn't as
commonly used as AH. It is the amount of minutes a battery
will last with a 25 amp load and not go below 10.5 volts
- CA... stands for Cranking Amps, this is rated measured
at 32º F. It is the number of amps that can be delivered
for 30 seconds while the battery stays above 7 volts. It's
an indication of what a battery can put out quickly when
trying to start a vehicle.
- CCA... stands for Cold Cranking Amps, and is similar
to CA but at a lower temperature. The rating is done a 0º
F, for 30 seconds and again until the battery gets to 7
What factors negatively effect battery life?
These are listed below. Preventing these from happening will
ensure additional longevity to your battery.

- Don't leave a battery uncharged for extended periods
- Never add tap water to a battery use distilled water
- Try and keep stored batteries below 110º F.
- Don't overcharge or undercharge a battery.
- Never short the battery lead together... very dangerous,
- Keep the battery terminals clean and tight so that current
- When working with batteries remove jewelry, have good
ventilation, remember that sulfuric acid is very dangerous,
keep off skin and away from eyes.
