Take a hydrometer reading of all the cells in the battery. This is as simple as squeezing the bulb and releasing it so that it sucks up some electrolyte, and then reading the specific gravity measurement. Refer to the spec sheet for the minimum acceptable reading and difference of specific gravity between cells.
Instructions
1. Accomplish a visual inspection of the battery. Provided there is any damage to the battery process or terminals, the battery should be replaced. Trial the electrolyte common and compose persuaded that the battery plates are covered.
2. Charge the battery fully before testing. Remove any surface charge to the battery by putting it to avail in its handle for a infrequent minutes.
3. Have a copy of the manufacturer's specifications for the battery nearby, as you will need to consult them as you test the battery.
4.Fathomless cycle batteries are beefy suited for marine, RV, solar force and analogous applications. They are discrepant from your criterion motorcar battery, and they must be maintained and checked regularly to receive the cool performance from the battery and the method to which they are connected. Division of this maintenence is the testing of deep-seated cycle batteries to clock provided they are in obligation of replacement.
5. Take a voltage reading with the voltmeter and compare it to the manufacturer specs for a fully charged battery.
6. Follow the instructions for the digital load tester, and test the battery while it is being placed under a load. This type of tester will not necessarily measure the battery capacity, but it will indicate whether or not the battery has an interior defect. A battery that fails any of the tests with these methods will need to be replaced.
