BatteryMINDer® Model 36271 Underwriters Laboratories (UL) REQUIRED SAFETY INSTRUCTIONS WARNING TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSON, OBSERVE THE FOLLOWING: 1. Do not expose charger to rain or snow. It is designed to operate ONLY INDOORS. 2. USE of any attachment not specifically recommended by the battery charger manufacturer for use with this exact model of charger may result in risk of fire & electric shock or injury to person. 3.
BatteryMINDer® Model 36271 instructions and those published by the battery manufacturer and the manufacturer of any equipment you plan to use in the vicinity of the batteries. Review cautionary markings on the products and the engine. 8. PERSONAL PRECAUTIONS when working with or near a lead acid battery. a. Someone should be able to hear your voice or close enough to aid you when working near a lead acid battery. b. Have fresh water and soap nearby case battery acid contact skin, clothing, or eyes.
BatteryMINDer® Model 36271 NEVER CHARGE A FROZEN BATTERY OR ONE AT A TEMPERATURE ABOVE 123° F. PREPARING TO CHARGE a. If necessary to remove batteries from equipment to charge. Always remove ground terminal first. Turn off all accessories in the vehicle, so as not to cause an arc. b. Be sure area around batteries is well ventilated while batteries are being charged. Force gas vapors away by using a piece of non-metallic material as a fan. c. Clean battery terminals.
BatteryMINDer® Model 36271 DC CONNECTION PRECAUTIONS a. Connect and disconnect DC output clips from batteries only after removing charger 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. FOLLOW THESE INSTRUCTIONS WHEN BATTERIES ARE INSTALLED IN EQUIPMENT (VEHICLE, PWC, BOAT, TRACTOR, ETC.) A SPARK NEAR BATTERIES MAY CAUSE BATTERIES TO EXPLODE.
BatteryMINDer® Model 36271 DO NOT CONNECT CLIP TO CARBURETOR, FUEL LINES, OR SHEET METAL BODY PARTS. Connect to heavy gauge metal part of frame or engine. h. When disconnecting charger, disconnect charger from AC outlet, then remove clips from vehicle chassis, and battery posts. Operating instructions for charge information. FOLLOW THESE STEPS WHEN BATTERIES ARE OUTSIDE OF VEHICLE OR EQUIPMENT. A SPARK NEAR THE BATTERIES MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERIES: a.
BatteryMINDer® Model 36271 QUALIFYING YOUR BATTERIES: Preliminary Requirements NOTE: The BatteryMINDer has no electrical output unless it is connected to healthy batteries. Testing the BatteryMINDer with a volt or an Amp meter without the unit being connected across good batteries 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® Model 36271 indicator found in each cell. Before proceeding further you must be thoroughly familiar with the safety and operating instructions. 4. Recharge the batteries with the BatteryMINDer to ensure that they are slowly and completely charged before you determine their condition. Allow each battery to “rest”* overnight for a minimum of 12 hours before testing with a temperature compensated hydrometer and/or digital type voltmeter only.
BatteryMINDer® Model 36271 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. Failure to do so will give you false readings indicating a battery that may not be in as good a condition as you may have thought. 2.
BatteryMINDer® Model 36271 Failure to test “rested” (see pg. 9) batteries will cause false readings. Be certain to read and understand all safety related instructions (pages 3 to 7) before proceeding further. 2. Measure battery voltage, without any load attached. If the voltage is less than 37.2 volts (Typically 50% of charge) the battery may be too heavily sulfated to be fully recoverable. If voltage is 37.

BatteryMINDer® Model 36271 Detailed Operation Instructions Model 36271 After carefully reading and understanding the Safety Instructions contained in this manual (pages 3 to 7) and having evaluated your batteries as described in Qualifying Your Batteries (pages 8 to 10) you are properly prepared to begin using your charger. 1. Attach output cord of charger to either the Battery Clip(s) Assembly (BCA) (supplied) or the Ring Terminal Assembly (RTA) (supplied) depending on your preference.
BatteryMINDer® Model 36271 golf cars, modern cars, trucks, boats, RVs, etc.) as far away from battery as possible for maximum safety. Never connect to any type of fuel line. Note: Older vehicles or other devices may be Positive ground installations requiring different connection recommendations. If unfamiliar or unsure which battery type of grounding system you have, check with our Tech Support personnel before proceeding further. Note: Temperature compensation Sensor Assembly (Part# ABS-248).
BatteryMINDer® Model 36271 LED Indicator will light GREEN. The charger will now begin charging by first checking the battery to determine its voltage and ability to accept a charge. Should the batteries not have a normal fully discharged voltage (31.5-V minimum) the unit will begin charging in the “Soft-Start” mode to determine if batteries can be safely charged. If it cannot, the Battery Connected – Error LED will flash RED and charging will be stopped.
BatteryMINDer® Model 36271 Note: If the battery system does not have a minimum no load OCV (Open Circuit Voltage) of 33 volts, the ERROR LED will light RED and charger will reject batteries. No further effort should be made to charge this battery with this charger or any charger. Discard this battery, unless it has just been subjected to a long period of continuous discharge under a load such as can occur with leaving lights on or cranking an engine excessively.
BatteryMINDer® Model 36271 If batteries are not defective they should be able to be fully charged after being restarted. After sufficient time has lapsed the GREEN charge LED Indicator will blink confirming when / if batteries are now fully charged. After carefully reading these instructions and Troubleshooting (pgs. 27 - 28) sections, should you still have questions, please e-mail our technical support department at: techsupport@vdcelectronics.com.
BatteryMINDer® Model 36271 INSTRUCTIONS: TEMPERATURE SENSOR Type: ABS-248 (At-the-Battery Sensor) If batteries are being charged or maintained in temperatures as low as 32°F to a high of 125°F this sensor must be used. Congratulations on purchasing the most advanced chargermaintainer-desulfator conditioner on the market today. Read you manual carefully to understand all of its features. Your temperature sensing system is made up of two components.
BatteryMINDer® Model 36271 Finally, if placing the sensor on the battery in not practical, place it where the ambient temperature the batteries are exposed to (surrounded by) can be sensed. When properly installed on the battery, your charger is set to provide your batteries with what they need to out-live and out-perform any similar battery used in the same application-conditions, by a factor of two (2). Temperature has a direct effect on the life of a battery.
BatteryMINDer® Model 36271 The chart below shows the need to regulate the output voltage of the charger to ensure against over or under charging your battery over a wide range of temperatures. Using your At-the-Battery Sensor will accomplish this better than any other known method.
