What is the SDG&E Technical Test – Red Battery?

The Technical Test—Red Battery is offered by SDG&E to job applicants competing for engineering apprenticeships, craft apprenticeships, or technical training. It consists of four tests, measuring candidates' knowledge and intuition of mechanics, reading comprehension, Computation skills and symbolic and logical reasoning.

What Is the Passing Score for The Technical Test?

Your success on the Technical Test—Red Battery is evaluated by so-called percentile score. This score measures your performance relative to other test takers. Thus, if you receive 90% for your Technical test, this does not mean that you have answered 90% of questions correctly.

Reading Comprehension Sample Question

The Government has recognised the housing problem and is now preparing legislation that will herald the start of a new house-building drive. It intends to support the building of a total of three million new homes by 2020, which would eventually mean creating an annual house-building target of 240,000 new homes a year.

The number 3,000,000 refers to houses that:

A. Are in the country.
B. Would be built in total.
C. Would be built annually.
D. Would be torn down.
Correct Answer
Incorrect Answer

The correct answer is (B).

The passage notes that the new legislation "intends to support the building of a total of three million new homes by 2020." Answers (A) and (D) are not mentioned in the passage, and answer (C) is incorrect as it states that 240,000 houses would be built annually, not three million.

Computation Sample Question

If 12 feet of barbed wire cost $4.80, how much will 5 feet cost?

A. 0.25$.
B. 0.40$.
C. 1.40$.
D. 2.00$.
E. 2.60$.
F. None of these.
Correct Answer
Incorrect Answer

The correct answer is D

In order to simplify the transition from 12 feet to 5 feet we can calculate the price of 1 foot (the division would be easier)
So, if 12 feet cost $4.80
1 foot costs $4.80/12= $0.4
Therefore, 5 feet cost $0.4*5=$2.00

About the Computation Test

This test measures your ability to solve problems narrated in short scenarios by using arithmetic operations. Usually, you will be told about people who either spend money on a certain amount of goods or receive money for certain services. Your task will be to calculate how much money the people would either pay or gain in specified circumstances. You will have only 10 minutes to solve 25 problems.

Mechanical Sample Question

Which fan requires a stronger engine to make the blades rotate? If both fans require the same engine then please select answer option 3.

Please select one correct answer option.


A. 1.
B. 2.
C. 3.
Correct Answer
Incorrect Answer

The correct answer is B.

The more blades a fan has the stronger engine it needs to make the blades rotate since the air resistance increases. Therefore the fan in fig.2 which has 6 blades requires a stronger engine than the fan in fig.1 which has only 4 blades.
The correct answer is - 2.
