Testing and Checking of GMDSS Batteries Required by SOLAS

There are three types of tests: 1. Daily on load/off load test, which ensures that all connections are intact and the voltage on loaded batteries do not drop too quickly. 2. Annual capacity test that measures the capacity of the battery in Ampere hours. The battery should be replaced if its capacity is less than 80% of the rated capacity. 3.

Measuring Batteries Capacity and Battery Health Test

A battery''s capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery''s capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell would be considered discharge testing

GMDSS equipment power

3) The test has performed for sufficient time to show that battery has 100% of its rated capacity. Say it has been 8 hours since the test started. And for 8 hours the current measure was 25A. So the battery has already delivered 200Ah (25A x 8 Hours). This shows that battery''s capacity is still 100%. In this case, this would conclude the test.
