The ordinary automobile battery works for approximately 3 to 5 years. But, according to some automotive websites, the normal automobile battery will survive only 3 years. Prolong your battery's life, and reduce your chance of sitting marooned in a parking lot due to a dead battery, by following these 4 simple maintenance tips.
>>>> 1). Battery water level...Most standard 12-volt auto batteries has 6 power cells [each cell develops 2 volts each, for a total of 12-volts]. Each one of these cells contains an ionized bath known as an electrolyte. For automobile battery's, the bath is a mixture of water and sulfuric acid [the water thins out the acid].
The electrolyte generates the electric current in the battery while you turn the ignition key. Check the water level in the cells every 2 to 4 months. You want the level to be just to the bottom of the refill hole. If it's low, use distilled water. Avoid using ordinary tap water for the process...It will corrode the terminals. Also using a Battery Tender can keep your battery active and ready when you need it.
This process sees to it that there's nothing between the connectors [the wires or cables in the car] and battery terminals to weaken the power connection. Remove the connectors by gentle twisting them back and forth while you gently lift upwards. [you'll need to loosen the connecting bolts first]. After you have cleaned the terminals, put the connectors back on by pushing each one firmly down and retighten the bolts. A coating the terminal-connector joints with high-temperature grease to cut down corrosion and rust is also a good idea.
>>>> 3). Not using your car for extended period of time...Disconnect your battery if you won't be driving the vehicle for more than 2 to 4 weeks. This prevents a slow loss of charge. Remove the connector for the negative [-] [BLACK] terminal. Place along side of the battery for easy access when you want to use the car again.
>>>> 4). Using the car for short runs...The alternator charges your battery while the car runs. Even so, the car must be running for at least 20 minutes to fully recharge the battery. Try to restrict the number of short trips you take. A good way to avoid this is to plan your shorter trips at the same tome. Many people use a device called a Battery Tender to keep their battery fully charged. Too [many starting cycles], coupled with shorter run times will leave your battery below the ideal charged specification. This cycle can shorten life for your battery.
