REQUIRED SAFETY INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
TOPERSON, OBSERVE THE FOLLOWING:
This unit is designed for protected use and should never be exposed
to rain.
Do not attempt to use the unit if it has been dropped or damaged.
Never attempt to charge a damaged battery, frozen battery or non-
rechargeable battery.
Do not use the unit in a closed area or poorly-ventilated area.
Never smoke, use an open flame, or create sparks near a battery
or unit during charging operation as this may cause an explosion /
explosive gas.
Do not operate the unit if the cord or plug is damaged.
Do not disassemble. VDC Electronics MUST be contacted for repair,
replacement or analysis. Keep away from infants, children and pets.
Switch off or remove AC power before connecting or disconnecting
to battery.
Refer to the battery Manufacturer’s specific recommended values
to determine if standard unit settings are correct. Contact VDC
Electronics Tech Support before making any changes
Check Battery Manufacturer’s specific precautions - such as removing
or not removing battery from aircraft before charging.
Always remove battery from aircraft before equalizing or desulfating.
Someone should be within range of your voice or close enough to
come to your aid if working near a lead-acid battery.
Wear protective goggles and turn your face away when connecting or
disconnecting a battery.
If battery acid contacts your skin or clothing, wash immediately with
soap and water. If acid enters your eye, immediately flush the eye
with running cold water for at least 10 minutes and seek medical
attention immediately.
To reduce risk of damaging the Battery, avoid dropping any metal
tools onto the battery.
Never rest the Battery being charged on top of your Battery
Charger.
The Battery Charger / power supply should be kept as far away from
the Battery as the output cables permit.
When using the Temperature Sensor at any location other then on a
battery the ring terminal must be insulated.

BatteryMINDer® Model 28252-AA-Series
Always follow battery manufacturer’s strict
instructions for proper care, charging and testing of
battery. Always use their FAA Approved “Instructions
for Continued Airworthiness” (ICA). Questions
relating to the subject should be referred directly
to the battery manufacturer to be certain of current
requirements that may have been added to or changed
since publication of their instructions.
NEVER CHARGE A FROZEN BATTERY OR ONE AT A
TEMPERATURE ABOVE 123° F.
PREPARING TO CHARGE
Always remove ground wire first.
Be sure area around battery is well ventilated while battery is
being charged. Force gas vapors away by using a fan.
Clean battery terminals. Be careful to keep corrosion from
contacting eyes.
Study all battery manufacturer’s specific instructions such as
recommended charge rates.
Determine condition of battery, by referring to instructions
herein, before ever attempting to charge or desulfate any /
all batteries.
Make sure unit is as far away from battery as output cables
permit.
Never place unit directly above battery being charged; gases
from battery will corrode and damage unit.
Do not operate unit in a closed-in area or restrict ventilation
in any way.
Do not set battery on top of unit.
DC CONNECTION PRECAUTIONS
Note: Steps to be done in a well-ventilated area.
a. Connect and disconnect DC output clips from battery only
after removing unit power cord from outlet.
b. Attach clips to battery posts and twist or rock back and forth
several times to make good contact. This tends to keep clips
from slipping off terminals and reduces risk of sparking.

UNIT LOCATION
A SPARK NEAR THE BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK OF A SPARK NEAR
BATTERY:
a. Connect (RED) charger clip to (POS+) post of battery.
b. Position yourself and free end of cable as far away from
battery as possible, then connect NEGATIVE (BLACK) charger
clip to free end of cable.
c. Do not face battery when making final connections.
d. When disconnecting unit, always do so in reverse sequence
of connecting procedure and break first connection while as far
away from battery as practical. Do not attempt to permanently
install unit not specifically designed-approved for permanent
installation, especially in a wet high moisture environment.

QUALIFYING YOUR BATTERY:
Preliminary Requirements
NOTE: The BatteryMINDer has no electrical output unless it is
connected to a healthy battery. Testing the BatteryMINDer with
a volt or an Amp meter without the unit being connected across a
good battery will result in a false reading. If you experience any
problems, or are not sure of how to properly use or connect your
BatteryMINDer, please e-mail our Tech Support Dept. at:
support line 800-379-5579 x206 (Eastern Time) (USA & Canada
ONLY). Be certain to leave your phone number with the area
code, time zone and the best time to call.
To gain the best result from your unit and to maximize the life and
performance of your batteries we strongly recommend you qualify
(test) your batteries before attempting to either charge-maintain
or desulfate them. Remember, even if you just purchased a
“new” battery it may have been subjected to conditions that
have caused “sulfation” such as an extended period at high
temperature (>=80°F).
NOTE: If your battery is new and you are certain it was
not subject to conditions that could have caused sulfation*,
even before you purchased it, then you can disregard our
recommendations for qualifying / testing your battery, before
using the BatteryMINDer.
* Such as high temperature storage (=/> 80°F) and/or allowed to
self-discharge to 24.8 Volts or lower.
Testing a Filler Cap Lead Acid Battery
1. Carefully remove all filler caps from your battery.
2. Check the water-liquid electrolyte level. If the level is low or
has ever been below top of plates, severe lead plate sulfation
has taken place. Significant recharge/reconditioning time is
needed to restore these plates to a condition where the battery
can be expected to function normally.
3. Refill each cell with distilled water only to the liquid level
indicator found in each cell. Before proceeding further you must

be thoroughly familiar with the safety and operating instructions.
4. Recharge the battery with the BatteryMINDer to ensure that
it is slowly and completely charged before you determine its
condition. Allow battery to “rest”* overnight or momentarily apply
a small load to remove the “surface” charge which creates false
voltage readings.
* “RESTED” = a battery that has been as fully charged as possible and left
disconnected from charger or any type load overnight. Apply a small load to
remove surface charge effect.
