REQUIRED IMPORTANT SAFETY INSTRUCTIONS WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSON, OBSERVE THE FOLLOWING:

1. SAVE THESE INSTRUCTIONS

1. This manual contains important safety and operating instructions for BatteryMINDer1215C.
2. Do not expose charger to rain or snow.
3. Use of an attachment not recommended or sold by VDC Electronics may result in a risk of fire, electric shock, or injury to persons.
4. To reduce risk of damage to electric plug and cord, pull by plug rather than cord when disconnecting charger.
5. An extension cord should not be used unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
   a. That pins on plug of extension cord are the same number, size, and shape as those of plug on charger;
   b. That extension cord is properly wired and in good electrical condition; and
   c. That wire size is large enough for ac ampere rating of charger as specified in Table 1 below.

TABLE 1
Recommended minimum AWG size for extension cords for battery chargers
AC input rating, amperesa		AWG size of cord
Equal to or greater than	But less than	Length of cord, feet (m)
		25(7.6)	50(15.2)	100(30.5)	150(45.6)
0	2	18	18	18	16
aIf the input rating of a charger is given in watts rather than in amperes, the corresponding ampere rating is to be determined by dividing the wattage rating by the voltage rating - for example: 1250 watts/125 volts = 10 amperes

1. Do not operate charger with damaged cord or plug – replace the cord or plug immediately.
2. Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; call VDC Electronics Tech Support Dept. 800.379.5579 x6 (ET) for advice.

4. To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning.

5. WARNING – RISK OF EXPLOSIVE GASES

6. WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.

7. To reduce risk of battery explosion, follow these instructions and those published by manufacturer of any equipment you intend to use in vicinity of battery. Review cautionary marking on these products and on engine.

8. PERSONAL PRECAUTIONS

9. Consider having someone close enough by to come to your aid when you work near a lead-acid battery.

10. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

11. Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.

12. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.

13. NEVER smoke or allow a spark or flame in vicinity of battery or engine.

14. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or other electrical part that may cause explosion.

15. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.

16. Use charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low voltage electrical system. Do not use battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.

17. NEVER charge a frozen battery or a battery at a temperature above 12 3^ F.

23. PREPARING TO CHARGE

1. If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.

2. Be sure area around battery is well ventilated while battery is being charged.

3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.

4. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve regulated lead acid batteries, carefully follow manufacturer's recharging instructions.

5. Study all battery manufacturer's specific precautions while charging and recommended rates of charge.

6. Determine voltage of battery by referring to car owner's manual and make sure it matches output rating of battery charger.

30. CHARGER LOCATION

1. Locate charger as far away from battery as D.C. cables permit.

2. Never place charger directly above battery being charged; gases

from battery will corrode and damage charger.
33. Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
34. Do not operate charger in a closed-in area or restrict ventilation in any way.
35. Do not set a battery on top of charger.
36. DC CONNECTION PRECAUTIONS
37. Connect and disconnect D.C. output clips only after removing A.C. cord from electric outlet. Never allow clips to touch each other.
38. Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through 16(d).
39. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION.
40. TO REDUCE RISK OF A SPARK NEAR BATTERY:
41. Position ac and D.C. cords to reduce risk of damage by hood, door, or moving engine part.
42. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
43. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,−) post.
44. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles), see (#45.). If positive post is grounded to the chassis, see (f).
45. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine block.
46. For positive-grounded vehicle, connect NEGATIVE (BLACK) from battery charger to NEGATIVE (NEG, N, -) ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine

block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine block.

1. When disconnecting charger, turn switches to off, disconnect AC cord, remove clip from vehicle chassis, and then remove clip from battery terminal.
2. See operating instructions for length of charge information.
3. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION.
4. TO REDUCE RISK OF A SPARK NEAR BATTERY:
5. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N, −) post.
6. Attach at least a 24-inch-long 18-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, –) battery post.
7. Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
8. Position yourself and free end of cable as far away from battery as possible – then connect NEGATIVE (BLACKger clip to free end of cable.
9. Do not face battery when making final connection.
10. When disconnecting charger, always do so in reverse sequence of connecting procedure and break first connection while as far away from battery as practical.
11. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.

START-UP OPERATING INSTRUCTIONS

1. Place the negative (BLACK) connection on the negative battery terminal.
2. Place the positive (RED) connection on the positive battery terminal.
3. Plug in the BatteryMINDer.
4. Charging will be GREEN (flashing) (see item #5 in Table 2.) Reverse leads if you do not see this.

CHARGING STAGES

• Soft-Start Mode: when battery voltage is below 10.5 volts due to deep discharge UNIT WILL ATTEMPT TO RECOVER IT. If successful unit will automatically switch to full power Constant Current mode. If if cannot, due to faulty shorted cell(s) it will shut down and indicate such. Battery MUST be REPLACED for both SAFETY as well as performance reasons.
• Constant Current: This stage recharges battery to 85% of its present capacity before automatically switching to Absorption stage.
• Absorption: completes the full charge before unit switches to Maintenance (aka Float) mode
• Maintenance (aka Float): keeps battery at full charge while continually desulfating it, ensuring full capacity for the longest possible life.

ADDITIONAL FEATURES

• Desulfation is the removal of sulfate build-up from your battery's plates. It occurs at all times the unit is connected.
• Short Circuit, Spark and Reverse Polarity Protection prevent the unit from having any output unless it is properly connected to your battery.
• Ambient Temperature Sensor (ATS-1), comes already installed on the Temperature Sensor input connector. Do not detach.
• Temperature Protection shuts down the unit if operating temperature is exceeded.

TROUBLESHOOTING

VDC Electronics Technical Support: [phone] x6

• Unit does not have an output unless connected to a battery. In order to test the output using a meter, connect the meter to your battery. When you connect the unit, you will see the voltage rise.
• If the unit is not in maintenance after 72 hours (solid GREEN), check to make sure your battery meets the minimum voltage of 3.0 volts. Unit will not operate if battery is below the minimum voltage of 3.0 volts. If there is a load on your battery, disconnect it and charge again. If the problem persists, your battery may be shorted or too badly sulfated.

Visit our learning center at BatteryMINDers.com for additional battery information.

MAINTAINING MULTIPLE BATTERIES

Batteries should be charged individually. To properly maintain multiple batteries they should all be the same type (gel, flooded or AGM) and condition. It is OK to mix deep cycle and starter. Charge each battery individually before connecting together. Never connect batteries at different states of charge. The charged battery will rapidly transfer energy to the discharged battery possibly causing catastrophic failure. Once the batteries are charged, use 18 gauge or greater wire to connect the batteries or for greatest safety protection and ease of use, consider investing in the BatteryMINDer Y-Connector Model 210AY with SmarTECHnology*.

See diagram on the Page 14 for the most common multiple battery configuration.

You must connect multiple batteries of the same voltage, wire them in parallel (BatteryMINDer positive to positive A to positive B, BatteryMINDer negative to negative A to negative B).

If connecting 2 batteries of half your unit's voltage (example: 6V batteries on a 12V unit), wire them in series (BatteryMINDer positive to positive A, negative A to positive B, negative B to BatteryMINDer negative). When wired in series they act as one large system at the combined voltage (example: 6V+ 6V = 12V). You can connect these systems in a series parallel configuration in order to charge or maintain 4 or batteries in groups of 2.

*BatteryMINDer® has developed a simple, safe and inexpensive method of connecting multiple batteries they call SmarTECHnology®-Y. Using their single SmarTECHnology-Y connector, two batteries can be maintained simultaneously using just a single output charger designed to maintain batteries. Adding additional Y-connectors allows from four (4) to eight (8) batteries to be connected depending on the maintenance charger capability.
