Quick-Start Instructions for BatteryMINDer 

Use ONLY after reading full Safety Instructions located inside.

1. Plug battery clip assembly (supplied) into 

mating plug at end of 

BM output cord OR 

attach Ring Terminal Assembly (supplied) 

to your battery’s terminals (Red +  Blue -)

2. Attach battery clips to posts or terminal 

clamps of battery (Red + Black -) (Green 

indicator will light when proper connection 

is made)

3. Plug 

BM into AC electrical outlet.

(Red indicator lites up) 

4. Allow 72 hours MAXIMUM (1 - 4 batteries) 

for Green indicator to blink (If Green 

indicator does not blink within 72 hours 

Press de-sulphation button) 

(blinking = full charge with battery in 

maintenance + desulphation mode) 

(blinking will continue indefinitely, until 

disconnected from battery)

Note: RED indicator will remain lit when plugged into

live ac electrical outlet. It 

should never go out, unless

outlet is switched off or 

BM has failed

HOW TO QUALIFY  YOUR BATTERY

You have purchased the number #1 rated “Computer Chip” charg-

er  / maintainer / conditioner with both Auto-Float Control™ and the

newest technological innovation Pulse Mode™ Circuitry. Although

designed primarily for use with flooded electrolyte -maintenance

type lead acid batteries, including marine deep cycle, it can be

used effectively with ALL maintenance-free types as well. Please

carefully follow these special instructions and the standard safety

and operating instructions for both maximum safety and complete

performance satisfaction.

Note: If your battery does not have a “resting”* voltage of 

5.25

volts MINIMUM

it cannot be charged or de-sulphated. (*Resting

voltage = Voltage in a battery that has not been charged or 

discharged within 8 hours MINIMUM).

It is extremely important that you determine the state of your bat-

tery’s “Health” before attempting to re-charge and re-condition your

battery. If any of your cells are shorted ( no reading on the hydrom-

eter tester) or the difference in charge level is greater than 0.50 SG

between any 2 cells (=  2 ball difference using the hydrometer

tester supplied ), your battery cannot be properly re-charged / re-

conditioned. Discard the battery in an appropriate, lawful manner.

Do not attempt to connect or charge ANY battery with the

BatteryMINDer

Charger / Maintainer / Conditioner before testing

your battery in accordance with the following: Your battery must not

be charged or dis-charged for a minimum of 10 hrs. Testing a bat-

tery which has not been at “rest” for 10 hrs. min. will result in inac-

curate readings.

Maintenance / Maintenance Free lead acid batteries 

(with filler caps or  manifold type covers) 

CAREFULLY

remove all 3 caps or both manifold type covers from

your battery. Carefully check water / electrolyte level. If level is now

or has ever been below top of plates, severe lead plate

“Sulphation” has taken place. Significant re-charge / re-condition-

ing time (weeks to months) will be needed to re- store those plates

to a condition were they can be expected to function normally.

Refill each cell with Distilled Water Only to a level of 1/4” minimum

over the top of the cell’s plates. Recharge the battery using

BatteryMINDer

to ensure it is slowly and completely charged

before determining its condition. If 

Battery-MINDer

fails to “blink”

within 72 hours, your battery may be to far gone to be re-condi-

tioned. However, to be sure press the de-sulphation button to set

the unit in the PulseMode. Allow battery to remain in this mode for

a 

minimum of 72 hrs

. before testing for “dead cells”, using the

special Hot / Cold calibrated Hydrometer Tester supplied. Here is

what to do:

NOTE: Read Tester Instructions carefully for best most accurate

readings.

Fill the Tester to a level sufficient to “float” all of the “balls”. Note the

number of balls which float in each of the 3 cells. If no balls float in

a cell, you can consider the cell to be “shorted”. Your battery is

beyond the point of being properly re-charged or re-conditioned.

Dispose of battery. If each cell “floats” 2 or more balls your battery

can be re-conditioned. Simply leave 

BatteryMINDer 

connected to

your battery at all times it is not in actual use, year-round. Your

unit’s special high frequency-current pulses will continue to bom-

bard the crystallized sulfuric acid, which has become deposited on

your battery’s cell plates.

NOTE: You cannot over de-sulphate your battery

.

IMPORTANT !

Read these special instructions before attempting to desulphate your battery.
