Transition batteries supply power to emergency lights, fire control, internal communication, etc. before the emergency gen comes on load just after the blackout and is supposed to give power for at least 30 mints . Battery capacity test how to do? With the approved load tester. The load tester will have FLC marked on it. And we are aware of capacity so we

7 SOURCES OF ENERGY

One method of checking the capacity is to fully discharge and recharge the batteries using normal operation current over a period of 10 hours. Assessment of the charge condition can be made at any time, but it should be done without significant discharge of the battery when the ship is at sea.

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.

6 FAQs about [How to check the battery capacity of emergency power supply]

What is a battery capacity test?

The annual capacity test measures the battery capacity in amperes. The battery must be replaced if the capacity is less than 80% of the nominal capacity. It is necessary to check the state of battery charge daily by measuring the specific gravity and electrolyte level. GMDSS batteries: tests and checks.

How to measure battery capacity?

Measurement can be with flow meter or with smaller measuring buckets/container. With capacity test, we measure the capacity of battery by same method. We charge the battery to full and then measure it by discharging. To discharge the battery, we apply a known load to measure its capacity. Capacity of the battery is measured in Ampere hour (Ah).

How long should a battery last after a capacity test?

After the capacity test, the measurement of the time a battery charges up to 100% should be done. Under SOLAS requirements this time should be less than 10 hours. The onboard batteries require no great maintenance. Just 2 parameters should be checked: the electrolyte level and the specific gravity of the electrolyte.

Is a deep discharge allowed during a battery capacity test?

SOLAS requires that a deep discharge of the battery is not allowed during the capacity test. During the test, you need to measure the voltage of each cell. The voltage should not be lower than 1 V in any cell or 20 V for the battery.

What should be avoided during a battery capacity test?

SOLAS requires that while performing the capacity test, deep discharge of the battery shall be avoided. We have already discussed what deep discharge is. During the test we need to measure the voltage of each cell. The voltage should not go below 1V in any cell or 20V for the battery pack.

What type of emergency power supply do I Need?

For reasons of reliability, a diesel engine prime mover coupled to a 3-phase generator and mounted together as one unit (generator set) is the most common type of emergency power supply in use. A large part of maintenance and operational testing revolves around the diesel-driven generator set ( Photo 1 ).
