If corrosion is present on the battery, you should remove the battery for cleaning by loosening the cable clamp bolts and disconnecting the hold-down clamp.

Disconnect the negative cable first, then the positive cable. Remove the battery thermo-wrap, hold-down clamp, and lift out the battery. Replace it with a battery of identical specifications. When removing the battery tray, disconnect the hose from the vacuum reservoir, remove the mounting bolt and nuts, and lift up the tray while disconnecting the electrical connector from the battery temperature sensor. Wash the tray and reinstall it following the reverse of the removal process.

Disconnect the negative battery cable and visually inspect the battery's state of charge using the indicator eye (if equipped). Charge the battery or add distilled water if needed. Use a hydrometer to check the specific gravity of the electrolyte in each cell. Perform an open circuit voltage test using a digital voltmeter, ensuring the battery voltage is above 12.5 volts. Use a battery load tester to evaluate the battery's ability to handle heavy amperage draw during startup and accessories operation. Cold temperatures may slightly affect the minimum voltage requirements. To test for battery drain, disconnect all accessories and check the current drain using a digital ammeter. Normal drain is around 100 milliamps or less, while excessive drain can cause battery discharge.

You should clean the cable clamps, terminals, and battery case with a solution of warm water and baking soda, taking care not to let the solution enter the battery.

Take this opportunity to inspect the carrier for any corrosion.

You should avoid creating sparks or lighting matches near the battery because it produces flammable and explosive hydrogen gas.
