Hello St. Johns drivers, let's talk about batteries. Car batteries are just like any rechargeable battery. They will eventually wear out and die. If you are shopping for a new battery in St. Johns , here's some auto advice to help you.
There are two measurements to consider when purchasing a new battery: cold cranking amps and reserve capacity. The power required to start a cold engine is measured in cold cranking amps. The number you need is determined by what kind of vehicle you drive and where you live. In general, higher-cylinder engines require more cold cranking amps than lower-cylinder engines. In other words, an eight-cylinder engine needs more cold cranking amps than a six-cylinder one. Also, diesel engines require more cold cranking amps than gasoline engines.
The weather where you live in Florida also determines the number of cold cranking amps you need. The colder the vehicle engine, the more power it takes to get it started. Also, cold Florida weather reduces the electrical efficiency of the battery, which reduces the amount of energy available in the battery to start the engine. Thus, in freezing temperatures, you need more power to start an engine, but you have less power available to get it started.
Your friendly and knowledgeable service advisor at Tuffy St. Johns in St. Johns can help you choose an appropriate battery for your vehicle and your lifestyle. If you need extra power owing to cold weather or a need for more reserve capacity, you may want to choose a heavy-duty battery. Just make sure it fits into your vehicle. An oversized battery may give you the power you need, but it's a serious safety hazard if the terminals come into contact with other parts of the vehicle.
Keep in mind that preventive maintenance performed at Tuffy St. Johns and good vehicle care can extend the life of your battery. Judicious use of electric gadgets and good driving habits are wise and can help you get the most out of your battery.
