Q: Can I charge more than one battery at a time with the
A: You can charge up to four batteries
of similar type and condition with the 12 volt
BatteryMINDers (model #12117). You can charge up to six
batteries of different type and condition with the 12 volt
BatteryMINDers (model #12248), the 24 volt BatteryMINDers
(model #24021), the 36 volt BatteryMINDers (model #36131) or
with the 48 volt BatteryMINDers (model #48041).
Q: How can I prevent
Thermal Fuse Burn-out?
Q: When does
BatteryMINDers start and stop charging my battery?
A: BatteryMINDers always remains on.
Its output will increase or decrease in response to your
battery's needs. It never shuts off. All batteries need to
be kept on continual maintenance charge to prevent discharge
and "Lead Plate Sulphation".
Q: What happens if I connect BatteryMINDers to my
A: Nothing! The green light will not
turn on. Simply reverse the battery clips and the green
light will come on and remain on until disconnected!
Q: Will BatteryMINDers first recharge bring my battery
to full capacity and then maintain it forever?
A: Yes BatteryMINDers fully recharges
your battery and keeps it at full charge indefinitely
(weeks, months, even years)!
Q: Does BatteryMINDers extend the life of my battery?
A: Yes, by preventing and eliminating
"Lead Plate Sulphation", which occurs when a battery is not
used or kept charged.
Q: Do I need to add water to my battery when connected
and maintained by BatteryMINDers?
A: BatteryMINDers prevents "boil-off"
due to overcharging, the main cause of water loss.
Q: How do I know if my battery is sulphated?
A: By carefully removing the battery
cell caps and looking into each cell you will see evidence
of a white crystal, frost-like coating. This is the
sulphation, which is permanently destroying your battery's
ability to store a charge.
Q: If my battery already has started to sulfate can
BatteryMINDers save it?
Q: I've seen other maintenance-type battery chargers for
less money. Why should I buy BatteryMINDers?
A: These other chargers shut off, then
wait for the battery to self discharge before turning back
on. This is when Sulphation occurs! Also, none of them can
reverse the sulphate build-up in your battery. Only the
BatteryMINDers can accomplish this safely and inexpensively.
Q: Anytime I leave my battery for even short periods of
time I find it either dead or dying. What can I do to
maintain my battery at full charge without overcharging it,
during these periods?
A: The BatteryMINDers prevents
batteries from discharging without the risk of overcharge no
matter how long they are left connected. Note: Please read
description of each unit very carefully before making your
Q: Is there a way to bring back a dying battery, even
one that is several years old?
A: Yes, with the BatteryMINDers you can
reverse the sulphation buildup that is killing your battery.
Q: How can I know if my battery is healthy and charging
system is working correctly before I have a problem starting
Battery and Alternator Conditioner Tester (Model 12104)
protects and displays the condition of your battery +
alternator / charging system at a touch of a button.
Q: What do the red and green lights mean in the
A: The red light comes on when the
BatteryMINDers is plugged in an electrical outlet. The green
LED lights when the unit is properly attached to the battery
posts. The blinking green light means that the
BatteryMINDers is in the desulphation-maintenance mode.
Q: When should I press the Desulphation button on my
A: This button should only be pressed
if the green light does not automatically blink within 72
hours. Note that you only need to press the button lightly
without using force. Pressing this button in less time will
prevent the battery from being fully charged or desulphated
in the shortest possible time. Note that the failure to
press the Desulphation button if the green light does not
blink within 72 hours may lead to unit burn-out or battery
Q: How do I tell if my BatteryMINDers is working
A: Test it on your car battery. Green
light should start blinking after a short period of time.
Test the battery with a voltmeter. It should read around 13
Q: How do I test my battery with a hydrometer?
A: 1. When using the tester for the
first time or after a long period of non-use, fill the
tester with battery fluid and let sit for 1/2 hour or
longer. This will soak the balls in order to give you more
accurate readings. Failure to do so will give you false
readings, indicating a battery that may not be in as good
condition as you may have thought.
2. After inserting the tester in a cell, gently tap the
tester several times against the inside the wall of each
cell to dislodge air bubbles that will cause more balls to
float than should. Failure to do so will yield false
readings indicating a battery that is not fully desulphated
or does not qualify for desulphation.
3. ALWAYS rinse the tester with fresh water after every use.
Failure to do so will cause false readings. Store the tester
in a holder to prevent breakage.
Q: Can I use model 12112 (12 volt BatteryMINDers) to
charge and maintain my Optima batteries?
A: Yes, you can use it on Optima
batteries for short periods (2-3 months) at a time. If you
need to maintain your Optima batteries for longer periods,
you should get the BatteryMINDers adjusted for Optima
batteries. If you need to maintain your Optima batteries
for longer periods, you should get the BatteryMINDer models
12248-ODY adjusted for Optima batteries.
