A Battery supplies the necessary electrical current to power the starter motor, which cranks the engine and initiates the combustion process. It ensures a constant and stable voltage supply to these electrical parts, enabling their proper and reliable operation. While the engine is running, the vehicle's alternator charges the 12-volt battery, replenishing the energy that was used during engine starting and powering the electrical unit.Attributes:• Provided with a 155 reserve capacity, this battery can provide the necessary burst of electrical current to crank the engine• Manufactured to precise specifications and are built for durability and reliability Applications:A Battery provides the high current necessary to start the engine. When the ignition is turned on, the battery supplies a large amount of electrical current to the starter motor, which then cranks the engine and initiates the combustion process.
