TESTING SERVICES

 

Input Power

Test to evaluate the conformity of the input power: Consists in measuring the circuit´s voltag

Dimensional tension

Test to evaluate the dimensional conformity: it consists of making the measurements dimensions.

Minimum average duration

Test to evaluate compliance of minimum average duration.

Leaks and deformations

He useful service and capacity of the cell is determined.

QUALITY POLITICS

Test to evaluate the conformity of the nominal voltage: Consists of measuring the voltage in open circuit of a determined number of batteries, with an specific equipment to carry out this activity, guaranteeing precision and accuracy in the measurements generated by the equipment.

DIMENSIONAL TENSION

Test to evaluate the dimensional compliance: Consists of making the measurements dimensions that can be obtained from a given number according to designation, of the batteries.

• For the designation batteries R03, R6, R14, R20, LR1, LR03, LR6, LR14 and LR20 and 4LR44 are the total height and the external diameter of the battery.

• For the 4R25X and 4LR25X designation batteries, the total height and width of the battery.

• For the 6F22 and 6LR61 batteries, the total height, width and length of the battery.

We guarantee the precision and accuracy of the equipment used through the metrological assurance and the capacity of the personnel for the application of the test.
We take into account the following precautions:

• We ensure that the type, measuring range, graduation and other specifications of the equipment are appropriate for the use to be given.

• When taking measurements, we eliminate dust and scratches from the piece. The sliding surfaces and the contact faces are completely cleaned. Lint-free paper or cloth is used.

• In precision measurements, we pay special attention to the reference temperature (if the piece is warmer than the equipment, it must wait until it reaches the reference temperature, ie the temperature of the equipment to be used).

• An excessive force of measurement is not used when determining the measurements of the batteries under test.

MINIMUM AVERAGE DURATION

Test to evaluate compliance of minimum average duration:

Consists in the simulation of the discharge of an electronic device, taking into account a discharge frequency and a resistance value.

• The discharge tests performed by the Laboratory are:

LEAKS AND DEFORMATIONS

The test begins exactly when the minimum average duration test ends, ie when the battery voltage first passes below the cut-off voltage and the useful service capacity of the battery is determined. The discharge must continue in the same way until the voltage falls below 40% of its rated voltage, where the batteries are dismantled, then a visual inspection is carried out, thus determining if there is any leakage (Unanticipated escape electrolyte, gas or other substances in a battery).

Then the dimensional measurements are made, as it was done in the first test, to determine if there is any type of deformation in the cell.
