FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR
BATTERY:
a.
Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger
diameter than NEGATIVE (NEG, N, -) post.
b.
Connect POSITIVE (RED) charger clamp to POSITIVE (POS, P, +) post of battery.
c.
Position yourself and free end of cable as far away from battery as possible - then connect
NEGATIVE (BLACK) charger clamp to free end of cable.
d.
Do not face battery when making final connection.
e.
When disconnecting charger, always do so in reverse sequence of connecting procedure
and break the first connection while as far away from battery as practical.
f.
A marine (boat) battery must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use.
AC POWER CORD CONNECTION INSTRUCTIONS
The plug must be plugged into an outlet that is properly installed in accordance with all local
codes and ordinances.
DANGER.
Never alter AC cord or plug provided - if it will not fit outlet, have proper outlet
installed by a qualified electrician. Improper connection can result in a risk of an electric
shock.
LENGTH OF CHARGE
The following instruction will allow you to determine how long it will take to bring a specific
battery to full charge.
a.
Test the battery for state of charger with a hydrometer or electronic percent-of-charge
tester.
b.
Determine the size of the battery in Amp-Hour or Reserve Capacity. If the ratings are not
printed on the battery, contact your local battery dealer for this information. These are the
only ratings that can be used to determine length to charging time.
c.
Use the battery rating, the charge level of the battery, and amp setting to be used on the
charger in the formula provided below.
Amp Hour Rating of Battery × Percent of Charged Needed
× 1.25 = Hours to Charge
Amp Setting Selected On Charger
NOTE: The length of charge times are approximate and varies from the battery to
battery. Always follow the battery manufacturer’s specific charging instructions.
CHARGING
NOTE: Before using the charger, please review all safety and connection directions.
Failure to do so can damage battery and cause serious injury or death.
Automatic Micro Process Control Unit Charge:
4 5
MZ1250 is fully automatic chargers come with a Micro-Processor Control Unit and
indicator LED. The Rate is 12V 1.25A.
STATUS INDICATING LIGHT: If the light is not lit, then the battery is not properly
connected and /or the charger is not plugged into AC power. The following describes
light operation:
Stage 1 —Diagnosis: Analysis the battery can accept charge or not, prevent charging from
proceeding on the a defective battery;
Stage 2—Bulk Mode (Constant Current): Fast speed charging, battery is 0% to 85% charged;
Stage 3—Absorption Mode (Constant Voltage) Absorption to voltage 14.6V, battery is 85% to
100% charged;
Stage 4—Storage/Float maintenance mode: Automatic On-off Monitoring. The charger dc
output will shut off and monitor a fully charged battery. If the battery falls below 12.8VDC, the
charger will restart and enter into stage one.
- The solid red light indicates that the battery charger has AC power
available and the microprocessor is functioning properly, then either the
battery voltage is too low(Less than 1.5Volts) or the output alligator clips
or ring terminals are not connected correctly;
- Whenever the green light is flashing, a battery is connected properly and
the charger is charging the battery. The flashing green light will remain on
until the charger completes the charging stage.
- When the green light is solid, the charger is complete and the battery
can be returned to service if necessary. It can also stay connected to
maintain the battery for an indefinite period of time.
•Connect the charger to battery per instructions.
•Connect the charger to AC outlet.
•If the charger does not detect a properly connected battery, the solid red light will be on until
such a battery is detected. Charging will not begin while the solid red light is on. When the
charging begins, the flashing green light will be lit steady.
•When charging is complete, unplug the charger from the AC outlet.
