Warning

Please read this manual carefully and operate this product according to instructions.

8. Supplementary instruction

The manufacturer of this product will offer a one-year warranty. But manufacturer may not take any responsibility for any failure caused by operation not in accordance with the instructions, in violation of the relevant knowledge or violate the laws and regulations. Manufacturer reserves the right to modify the product without notifications for the difference generated by the modification made in this manual.

1. Notes

1 ) The operation site must be ventilated with good environment. It’s

better to do the test under room temperature.

2 ) Do not use it outdoors when weather is bad such as rainy, snow, etc. and keep it away from rom open flame, water, and inflammable, explosive objects as far as possible when using.

3 ) Before using the instrument, you must correctly distinguish the positive pole (+) and negative pole (-) of battery, then connect the red casing clip of instrument to the positive pole (+) of battery, and connect the black casing clip to the negative pole (-) of battery. And connection must be firm.

seconds or start the motor again. In fact, the power is consumed the most when starting the engine, the battery voltage can be dropped to 10.5V and below from normal 12.5V at the moment of large ampere output.

The greater of the cold cranking ampere has larger help for such

unsmooth starting.

◆ CA - Cranking Ampere

Its meaning is similar to CCA, unit is also Ampere, its only difference from

CCA is the temperature. CCA is the result under the temperature of -17.8℃, while CA is the result under 0℃. If the battery marked with CCA and CA, the CA value will be lower than CCA, because the lower of the temperature, the worse performance of battery it will be.

◆ AH - Ampere Hour

It is the standard defined by Japanese industrial standard (JIS). Simply put, the battery is discharged at a fixed ampere can maintain for 20 hours, voltage can be 10.5V and above, 21 this fixed amperes multiply by hours is Ampere Hour. For example, 20hours and discharged at fixed 20 Ampere, the ampere hour of battery is 100.

◆ DIN - Germany standard

The ampere of battery can reach 9.0V for 30s under the cold temperature of 0°F(-18℃), and maintain the minimum voltage, while at 8.0V, mai nt ai n fo r 150s.

◆ IEC - The international association of electronic science and

technology

Under the average current intensity, each battery soaked in 0°F (18℃) for cooling, the lowest voltage is 8.4V and maintained for 60s.

◆ BSR - British national inspection standard

Under the average current intensity, each battery soaked in 0°F(-18℃) for cooling, the lowest voltage is 6.0V and maintained for 180s.

◆ BCI - The international association of battery

Under the average current intensity, each battery soaked in 0°F (-18℃) ~

-20°F(-29℃)for cooling, the lowest voltage is 7.2V and maintained for 30s.

The excellent materials, reliable process and design, advanced circuit control, and good details and quality control system guarantee the high quality, accuracy and reliability of the instrument.

Battery acid is mixed by distilled water + pure sulfur acid at the proportion of

1.260 / 20 ℃, for a brand new battery, if the battery acid is under the normal range, the acidity is fixed, if the battery acid is less than the normal level, add distilled water in addition to maintain water level, PH value should also be maintained.

If the battery is working properly, then in addition to PH value is fixed, the

proportion value will be in a certain range.

12.4 7 0 ~ 8 0 %

12.1 50% 1.16

12 25% 1.13

After the batter is fully charged, the proportion of battery acid can't reach

1.26 ~ 1.28, measured voltage cannot reach to 12.7V and above, which indicates the storage capacity of the battery has been decreased, at this time if the proportion of battery acid is deliberately adjusted to 1.26 (adding sulfuric acid water proportion), will not bring the dying back to life, but may let the battery dead faster, because acidity of battery acid will also increase, but not increase the voltage.

7. How much do you know about

vehicle battery

7-1 Internal resistance of different types of

battery is different

The same type of battery, internal inconsistences are diff er en t du e to

different chemical characteristics. Battery internal resistance is small, we usually use the milliohm unit to define it. Resistance is an important technical indicator to measure the battery performance. Under normal condition, the battery discharge capacity of small internal resistance is strong, while the battery discharge capacity of large internal resistance is weak.

7-2 The amount of storage capacity of the

battery cannot be measured by intuition

You can use the hydromet er t o me as ur e th e wo rk in g st at e of t he b at te ry.

Details:

Test results:

“Current voltage:12.38 V”: voltage is the battery not connected to the load provided by instrument, the voltage will be changed when testing output voltage of battery.

“Load voltage: 11.85V”: the voltage is battery connected to the load provided by instrument and basically stabilized, this value is the retention value of the result of discharging test.

“Rated capacity: 60 Ah ”: rated nomanil AH capacity of battery set by user. "Internal resistance of battery: 4.78 mΩ" : the internal resistance

parameter of battery, determined in test process. In order to facilitate a better understanding of the battery status, you can use no-load voltage of measured battery of the instrument for determination (DO NOT need to hold

the load switch). The deterimination conditions are shown in the table below.

◆ (12V battery)

Test result

Battery status

“ Sufficient” ( LED green)

The battery is in good status. Power is sufficient.

“ Low ” ( LED yellow)

If the brightness of LED is stable, battery is OK, but power is insufficient.

“ Replace ” ( LED red)

At this time, the re will be alarm, indicating th e battery is failed. Under this situation, we should loosen t he load s wi tc h, and ch ec k the no-load voltage value displayed on LE D digital display. I f the value returns to 12V and above rapidly, indicating battery is failed. If voltage value is slowly r ec ov er ed , the battery may not fail, but yo u need to do further testing.

Internal resistance 4. 75 m Ω

The higher of CCA value of battery, the internal resistance is lower

generally.

Note: the sta ndard of the in ternal resi stance will be di ffere nt due to the different
