TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSON, OBSERVE THE FOLLOWING: SAVE THESE INSTRUCTIONS This manual contains important safety and operating instructions for BatteryMINDer Models 36271 and 48021. Do not expose charger to rain or snow.
BatteryMINDer® Models 36271 & 48021 or otherwise damaged in any way; call VDC Electronics Tech Support Dept. 800.379.5579 x6 (ET) for advice. 9. Do not disassemble charger; call VDC Electronics Tech Support Dept. 800.379.5579 x6 (ET) for advice when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire. 10. To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning.
BatteryMINDer® Models 36271 & 48021 h. Use charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. 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. i. NEVER charge a frozen battery or a battery at a temperature above 123° F. 13. PREPARING TO CHARGE a.
BatteryMINDer® Models 36271 & 48021 16. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY: a. Position ac and DC cords to reduce risk of damage by hood, door, or moving engine part. b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons. c. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,–) post. d.
BatteryMINDer® Models 36271 & 48021 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 technical support at: techsupport@vdcelectronics.

BatteryMINDer® Models 36271 & 48021 Testing with a Hot/Cold Calibrated Hydrometer Tester Read the tester instructions carefully for most accurate readings. 1. When using the tester the first time or after a long period of non-use, fill the tester with the battery fluid and let it sit for 1/2 hour or longer. This will soak the balls in order to give you more accurate readings.
BatteryMINDer® Models 36271 & 48021 3. Connect the BatteryMINDer to the battery. 4. Charge battery to its maximum level. Allow battery to remain for a minimum of 72 hours before retesting. If improvement is seen, continue until battery voltage reaches full capacity level or no further increase is seen.
