INTRODUCTION
Your new Model B-300 battery analyzer employs the latest electronic technology called Conductance testing to determine if a battery is really bad or simply needs recharging.

THE CONDUCTANCE TESTING ADVANTAGE

  • No potentially damaging and dangerous heavy loading
  • No time consuming need to recharge and retest
  • No need to input the battery’s Cold Cranking Amps (CAA) to test its’ condition.
  • No need to convert the battery’s rating system
  • No adjustments necessary for hot or cold temperatures

MEASURING BATTERY CAPACITY

Unlike other battery testers that require inputting the Cold Cranking Amps (CCA), the B-300 passes this by measuring the capacity of the battery and expressing it as a percent of full capacity.

UNIQUE BARGRAPH CONDITION INDICATOR

The B-300 features a unique color-coded BARGRAPH to give the technician an instantaneous indication of the battery condition. Just connect the tester to the battery, press TEST and the BARGRAPH immediately displays the battery condition. Batteries displaying in the green section of the BARGRAPH are good whereas batteries in the red section require replacement. Marginal batteries are displayed in the yellow-orange section of the BARGRAPH.

HOW DOES A LEAD ACID BATTERY GENERATE ELECTRICITY?

A lead acid battery stores chemical energy. The chemical energy is created by the chemical action between the materials which form the positive and negative plates of the battery and the electrolyte (sulfuric acid). When the battery is connected to an external load such as a vehicle starter, the acid reacts with the battery's plates and the chemical energy is then converted into electrical energy.  
 

THE CHARGING/DISCHARGING CYCLE 

Just as in a flashlight type dry cell, the lead acid battery chemicals are consumed when electrical power is extracted. When a lead acid battery is discharged, some of the sulfate from the acid adheres to the plates and is lost or consumed. This causes the sulfuric acid to gradually lose strength. But unlike the dry cell battery, the chemical changes in a lead acid battery can be reversed by charging.

WHY DOES A LEAD ACID BATTERY GO BAD?

Age: Although charging causes the sulfate deposited on the plates to return to the acid, the process is not perfect. A small amount of sulfate insulating residue (sulfation) remains on the plates of the battery. With each charge/discharge cycle of the battery this residue accumulates. This process eventually results in diminished electrical conductivity of the plates as well as permanently diluted sulfuric acid and eventually the battery will no longer maintain a charge.  

Premature Failure: One common cause of premature battery failure is loss of electrolyte due to under hood heat or overcharging. Other causes, though less common are deep discharges (leaving your lights on), using an undersized battery, undercharging, loose alternator belt, or excessive vibration due to loose hold-down clamp. Sometimes it is not just the sulfation, but the occurring mechanical damage that causes premature failure. Shorted cells, open inter-cell connectors, plate erosion and plate expansion are examples of mechanical damage causing premature failure.  

WHAT IS A BATTERY'S STATE OF CHARGE?

A battery's state of charge is the open circuit or unloaded voltage across the positive and negative terminals. Under unloaded conditions, with no surface charge, a battery displaying 12.7V or above is considered to be fully charged whereas a battery displaying 11.8V or below is considered to be fully discharged.  

HOW DOES A CARBON PILE TESTER WORK?

Until recently, the most effective way to determine the condition of a battery was to measure the voltage drop while draw-ing hundreds of amperes (almost a short) from a near fully charged battery. To achieve this load, large resistors (carbon piles) are applied across the battery's terminals for a short period of time (approx. 15 seconds) and the resulting voltage is read. Typically, the voltage on a good battery will not drop below 9. 7 Volts at 80°F (9. 1 V at 30°F). Although widely used, this method can permanently damage a battery, cause potentially dangerous sparks and requires an adjustment to the reading to compensate for low ambient temperatures. 
 

OPERATING INSTRUCTIONS

Always use caution when working with batteries!

Checking Battery Condition

1. Connect the red clip to the positive battery post and black clip to the negative post. The display will show the battery voltage.

2. Press the Test Button.

3. The digital display will show the % capacity of the battery and the BARGRAPH will display the battery condition as Good, Marginal or Bad. See below:

In- Vehicle Testing

Note: Before Testing the battery, turn off vehicle and all accessory loads. Remove surface charge (battery Voltage greater than 12.8 volts) by turning on the headlights for 15 seconds.

Checking Charging System (Alternator)

  1. Check first for a loose, worn or broken alternator belt. If okay, proceed to #2.
  2. Connect the red clip to the positive battery terminal and the black clip to the negative terminal and start engine.
  3. With engine running, and lights on, voltage reading on the display should read between 13.0 and 15.0 volts.

Checking Starter System

  1. Connect the red clip to the positive battery terminal and the black clip to the negative terminal.
  2. Disengage the ignition. (Check manufacturer’s instructions).
  3. Read the voltage displayed while cranking the starter
    If the voltage is equal to or greater than 9.6 volts, starting system is OK. If the voltage is less than 9.6 volts, starting system has a problem. Check wires, connections and starter.

Selecting Battery Size for Test

  • To Test all standard auto and truck batteries: No battery size selection is necessary. The B-300 will automatically default to this position when powered on.
  • To Test all smaller, non-automotive 12- volt batteries such as motorcycle, water-ski and lawnmower batteries: Press the sensitivity select key once. The led indicator will shift to show the new position. Note: Pressing the selector button a 2nd time will return to the standard size position.

  

Low Battery Indicator

The low voltage battery Indicator led (see figure above) will turn on if the battery voltage is below 12.3 volts. If the battery tests Bad or Marginal fully charge the battery, recharge and retest. Note: Recharging and retesting will result in more accurate results for bad or marginal batteries.

Defective Cell Indication

Capacity displayed below 20% indicates that the battery has a defective cell. Defective battery cells are usually open or shorted and the battery must be replaced.

DISPLAYING BATTERY CAPACITY

The B-300 displays the battery’s available capacity as a percent of full capacity. This eliminates the need for time consuming CCA input or conversions to other rating systems. By tracking actual SAE battery rating specifications, a battery showing 80% available capacity and above is considered Good whereas a battery showing less than 70% is considered Bad. Batteries showing between 70% and 80% available capacity are Marginal and other factors such as the environment conditions and vehicle type may be considered before replacing. Note: Although not necessary with the B-300, the battery’s available CCA’s (or any other rating system) can be determined simply by multiplying the percent available times the battery’s rating.

HELPFUL HINTS

SELECTING PROPER BATTERY SIZE

Use the battery manufacturer's guide for the recommended CA and Group # for a particular vehicle model. There are two other battery ratings that should be considered depending on the climate where it will be used: CCA (Cold Crank-ing Amps) and RC (Reserve Capacity) . In colder climates higher CCA ratings are more important.  

CCA - Discharge load measured in amps that a fully charged battery at 0 ° F can deliver for 30 seconds while maintaining its voltage above 7.2V  

RC - Number of minutes a fully charged battery at 80.F can be discharged at 25 amps until the voltage drops below 10.5 volts.  
 

REMOVING AND INSTALLING BATTERIES

  • When replacing a battery always remove the NEGA-TIVE cable first. 
  • Be careful not to reverse the polarity when installing a battery. This can severely damage or destroy a cars electrical system or cause the battery to explode. 
  • Attach the POSITIVE cable first and then the NEGA-TIVE last when installing a replacement battery. 
  • NEVER disconnect a battery cable from a car with the engine running. 

RECHARGING BATTERIES

  • Before charging, do not add water if the electrolyte is covering the top of the plates. Recheck electrolyte level after charging.
  • Reinstall vent caps BEFORE recharging. Recharge only in well ventilated areas, and wear protective eye ware.
  • No smoking, sparks or open flames while the battery is recharging because they give off explosive gases.
  • Do not recharge a sealed battery with current above 25 amps.
  • Turn off charger before connecting or disconnecting cables to a battery.
