Projecta BTL300 Operating Instructions Manual

6/12/24 VOLT CARBON PILE

1000 AMP

LOAD TESTER

P/No. BLT300

CAUTION – BATTERIES PRODUCE EXPLOSIVE GASES, TO REDUCE THE RISK
OF EXPLOSION OR INJURY ALWAYS ENSURE:

• No sparks or flames are present

• Eye protection is worn

• All vehicle or battery manufacturer’s instructions are followed

• The load is “OFF” before connection or disconnection

• Correct polarity, do not reverse connect

• Beware of moving engine parts

NOTE

Carbon pile load testers produce a great amount of heat while the load is ‘ON’, do not apply the load for
more than 20 seconds at a time and allow time to cool between tests.

When operating the unit for the first time it is normal for a small amount of smoke to develop as the
lubricants used in the manufacturing process burn off.

OPERATING INSTRUCTIONS

Battery Load Test

1. Connect the RED clamp to the Positive (+) battery terminal or post

2. Connect the BLACK clamp to the Negative (-) battery terminal or post.
Note: If testing a battery in the vehicle, ensure the engine and all loads are‘OFF’.

3. Check the battery’s open circuit voltage (OCV) on the DC Volt meter.
– If the needle is in the green section of the ‘State of Charge’ scale (above 6.5V, 12.5V, 24.5V) the battery

has sufficient charge to test.

– If the needle is in the red section (below 6.5V, 12.5V, 24.5V) the battery needs to be fully charged

before testing.

4. Determine the battery’s rated capacity in Cold Cranking Amps (CCA) or Amp hours (Ah) and calculate the
correct load current:
Cranking batteries with: Load current = 1/2 the CCA rating
Deep Cycle Batteries with: Load current = 3 x Ah rating

5. Turn the ‘Load Control Knob’ clockwise until the correct load current is reached on the DC Amps meter.

6. After 15 seconds the buzzer will sound to indicate the correct test time, immediately read the DC Volt
meter.
– If the needle is in the green area of the ‘Battery Test’ scale the battery has passed the test.
– If the needle is in the red area the battery has failed the test, quickly reduce the load current until the

needle moves back into the green area, and then read the approximate battery capacity in Ah or CCA
from the DC Amps meter.

ONCE THE METER HAS BEEN READ THE LOAD MUST BE TURNED OFF
IMMEDIATELY TO PREVENT OVERHEATING – TURN THE LOAD CONTROL
KNOB FULLY ANTI-CLOCKWISE.

Note: Battery ouput varies due to temperature change, the ‘Battery Test’ scale has four temperature
calibrations (21

o

, 10o, -1oand -18oCelcius). Use the closest scale to the approximate ambient temperature.

For a more accurate result at different temperatures, use the following graph to determine the minimum
voltage the battery can reach while under test.
