If you've ever noticed your vehicle's lights are dim or not working at all, the problem could be many things. But one possibility is your battery cables aren't doing their job. A power outage in your vehicle is similar to one in your house and needs to be repaired to get things back to normal. Battery cables connect your vehicle's battery to the vehicle itself. There is a positive cable when provides the power and a negative cable that connects to the vehicle chassis and provides a ground for electrical components. A failing battery cable may cause your vehicle not to start. Your starter may turn over very slowly. Or you may just hear a series of clicks. One other clue is on your dash—the battery warning light. There are many things that can cause power issues in a vehicle, but it's important to keep battery cables clean and maintained. Salt and corrosion are enemies to any power system. A technician can keep things in t ... read more

OK, so you probably take your vehicle's battery for granted. Turn the key or push a button and it starts right up. During times of warmer weather, you probably think your battery can take it easy. But it may surprise you to learn that hot weather can be much harder on a vehicle's battery than cold. So it's wise to know what condition your battery is in BEFORE you find out the hard way—being stranded by a dead battery. Your vehicle's battery won't last forever; an average battery will last 3-5 years. When's the last time yours was replaced? You probably have no idea. Your vehicle will usually give you some hints that it's in need of attention. See if any of these are familiar: your engine doesn't turn over as quickly as it used to your headlights are a little dimmer your Check Engine or Battery dashboard light is on you hear a click when you try to start your vehicle some electrical equipment in your vehicle isn't behaving the way it used ... read more

When it comes to your vehicle, it all starts with the battery. Proper battery maintenance is important for two reasons:First, your vehicle won't start or run without it. Second, it is the key to the long life of your auto electrical system. If your battery isn't working efficiently, your alternator has to work overtime to make up for it, and other electrical components can suffer as well.A number of years ago sealed batteries were introduced to the local San Diego, CA, market. They were hailed as being 'maintenance-free batteries.' While it is true that you can't get in and adjust the electrolyte levels of a sealed battery, it is by no means maintenance free.Batteries are very sensitive to changes in the weather around CA. Temperature really affects auto battery performance. A battery inspection is an important part of your spring and fall checkups. Next time you're under your hood, take a look at your battery. Is it clean and free of residue? A dirty battery will drain. Is there cor ... read more

It's important for San Diego drivers to know battery basics. First, let's talk about which is harder on a battery – hot or cold CA weather. Most San Diego area drivers think it's cold weather because that's when we call on our batteries to have enough power to start a cold vehicle engine. However, heat does more damage to a battery than cold. Truth is, our batteries start to die a little from day one. Keeping a full charge slows the process, which is hard with short San Diego trips because the alternator doesn't have time to fully recharge the battery from starting the engine. San Diego drivers can top off the charge with a computer controlled battery charger – say, once a month in the summer and every three months during the winter.As far as how long a battery will last, statistics show that 70% have given up the ghost within four years. By that time, they aren't capable of taking a full charge like they used to ... read more

Hello, welcome to John's Automotive Care. Today's focus is batteries. It seems like everything in San Diego runs on batteries. Of course, the batteries we're most concerned with here at John's Automotive Care are those in our customer's vehicles. Just like the batteries in our smoke detectors or TV remote, they wear out and need to be replaced . This can be thought of as the power output used to start a cold vehicle engine. The number of cold cranking amps you need depends on your vehicle and where you live in CA, specifically how cold it is. (Many San Diego drivers have first-hand experience trying to start their car on a cold winter morning.) The two factors are that the colder your vehicle's engine is, the more power it takes to turn the engine over to get it started. It has all that cold, sluggish oil to contend with.The other factor is that the chemical reaction in the battery that creates electrical energy is less efficient when the temperature dips ... read more

Hello San Diego drivers! Need a new battery? There is a good chance that you do – 70% of batteries need to be replaced within four years. As your battery discharges and then recharges as you drive around San Diego, bits of the surface of the battery plates disintegrate. As this process continues over a few years, the alternator has to work harder to supplement the battery charge. Over time, enough of the battery is damaged that it can no longer hold a charge and it needs to be replaced. This also speeds up wear on the alternator.Your John's Automotive Care service advisor can help you determine the right vehicle replacement battery for the way you drive around San Diego, as well as the CA climate and durability needs.Contact John's Automotive Care for information on battery replacement.Give us a call.

Hello San Diego 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 San Diego, 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 CA also determines the number of cold cranking amps you need. The colder the vehicl ... read more
