6 FAQs about [High temperature test methods for lead-acid batteries]

How to test a lead-acid battery?

The charging method is another key procedure in any test specification. Most documents follow the approach that it shall be ensured that the lead–acid battery is completely charged after each single test. The goal is that the testing results are not influenced by an insufficient state-of-charge of the battery.

What is a battery test?

During the test it is measured how much capacity (current x time expressed in Ah) the battery can deliver before the terminal voltage drops to the end of discharge voltage x number of cells. The current shall be maintained at a constant value.

What are the standards for battery testing?

There are a number of standards and company practices for battery testing. Usually they comprise inspections (observations, actions and measurements done under normal float condition) and capacity tests. Most well-known are the IEEE standards:

How does a battery test work?

When used regularly it can be used for tracking the battery’s health and actual capacity and estimate remaining life of the battery. During the test it is measured how much capacity (current x time expressed in Ah) the battery can deliver before the terminal voltage drops to the end of discharge voltage x number of cells.

What does the lead–acid battery standardization Technology Committee do?

The lead–acid battery standardization technology committee is mainly responsible for the National standards of lead–acid batteries in different applications (GB series). It also includes all of lead–acid battery standardization, accessory standards, related equipment standards, Safety standards and environmental standards. 19.1.14.

What is a battery insulation test?

The insulation resistance is measured across one of the terminals of the battery to some ground, presumably the battery rack or tray. It is a very easy test to perform and provides for a lot of confidence in the overall state of electrical insulation. This test applies a DC voltage, say 500 Vdc, between the buss, off-line and the rack.
