BatteryMINDer® Model 28252-AA-Series REQUIRED SAFETY INSTRUCTIONS WARNING TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TOPERSON, OBSERVE THE FOLLOWING: • This unit is designed for protected use and should never be exposed to rain. • Do not attempt to use the unit if it has been dropped or damaged. • Never attempt to charge a damaged battery, frozen battery or nonrechargeable battery. • Do not use the unit in a closed area or poorly-ventilated area.
BatteryMINDer® Model 28252-AA-Series Always follow battery manufacturer’s strict instructions for proper care, charging and testing of battery. Always use their FAA Approved “Instructions for Continued Airworthiness” (ICA). Questions relating to the subject should be referred directly to the battery manufacturer to be certain of current requirements that may have been added to or changed since publication of their instructions. NEVER CHARGE A FROZEN BATTERY OR ONE AT A TEMPERATURE ABOVE 123° F.
BatteryMINDer® Model 28252-AA-Series UNIT LOCATION A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY: a. Connect (RED) charger clip to (POS+) post of battery. b. Position yourself and free end of cable as far away from battery as possible, then connect NEGATIVE (BLACK) charger clip to free end of cable. c. Do not face battery when making final connections. d.
BatteryMINDer® Model 28252-AA-Series 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 Tech Support Dept. at: techsupport@vdcelectronics.
BatteryMINDer® Model 28252-AA-Series be thoroughly familiar with the safety and operating instructions. 4. Recharge the battery with the BatteryMINDer to ensure that it is slowly and completely charged before you determine its condition. Allow battery to “rest”* overnight or momentarily apply a small load to remove the “surface” charge which creates false voltage readings. * “RESTED” = a battery that has been as fully charged as possible and left disconnected from charger or any type load overnight.
BatteryMINDer® Model 28252-AA-Series TESTING A SEALED, AGM LEAD ACID BATTERY These batteries have no filler caps or manifold-type covers. Because you cannot gain access to the interior of your battery you cannot test it with a hydrometer. USE A DIGITAL VOLTMETER ONLY: 1. Recharge the battery with the BatteryMINDer to ensure it is as completely charged as possible, before you determine its condition. Allow battery to “rest” (see pg. 9) overnight before testing with a digital voltmeter only.
BatteryMINDer® Model 28252-AA-Series Simplified Operating Instructions The BatteryMINDer has no electrical output unless it is connected to a battery with a minimum of 6-Volts or when in Power Supply Mode. • Attach Temperature/Voltage Sensor to TempSensor Receptacle A and Ring Terminal to positive Battery Terminal. • Attach Battery Connector Attachments (BCA) to DC-CORD Output of unit. • Plug AC Power Cord into 95 - 240 Vac electrical outlet. Turn AC POWER Switch On.

Rev.
BatteryMINDer® Model 28252-AA-Series When using the Temperature Sensor at any location (other then on a battery) the ring terminal must be insulated, heat shrink tubing is recommended. If using the A2GPU-1 or A2GPU2 and are unable to place the Temperature Sensor on a battery terminal, it may be inserted into the unused cavity of the A2GPU plug and secured with cable clamp. A2GPU-1 Plug Instructions 1. Connect A2GPU 2. Turn on 28252 3. Hold down “Power Supply/Charge” for 5 seconds and release 4.
BatteryMINDer® Model 28252-AA-Series OPERATING INSTRUCTIONS 1. Pre-Charge Check (a) Check the Battery Electrolyte level (Non-sealed Batteries). If necessary, remove the vent caps and add distilled water so levels are halfway between the upper and lower fill lines. (b) Location – Ensure the Battery is in a well ventilated area. Keep the Unit as far away from Battery as the cables permit.
BatteryMINDer® Model 28252-AA-Series 3. Aviation charge mode connection (1). Connect to 24V Aviation battery. (2). You MUST connect Temperature/Voltage Sensor ABS-2825 (no substitute) to the Positive (+) battery terminal. (3). Connect the output DC cable RED clips to the battery Positive polarity (+), the BLACK clips to the battery Negative polarity (-). 4. Connect the unit to AC input power Turn on the AC power switch.
BatteryMINDer® Model 28252-AA-Series 5. The Charging Process The Charging LED’s will indicate the Charging Stages. LCD will display the values and functional setting. The charging stages are as follows: • Soft Start: Charges the battery using half the maximum current until the battery voltage is over 22V (indicated by YELLOW Bulk LED FLASHING).
BatteryMINDer® Model 28252-AA-Series To Change the Mode on the BatteryMINDer 28252-AA-Series: • After the unit is powered on, if you do not press a Mode Button within 30 seconds, you will need to press the Mode Button TWICE • If the unit has not had a Mode changed within 30 seconds, you will need to press the Mode Button TWICE In each instance, you only need to press the Mode Button ONCE if done within 30 seconds after the previous operation This is a safety feature to help prevent inadvertent operations,
