Make Sure Your Car Battery Is Ready for “Summer” in San Francisco

Car Battery

If you live in the Bay Area, you’ve no doubt already memorized Mark Twain’s famous assessment of the weather: “The coldest winter I ever spent was a summer in San Francisco.”

What never gets mentioned when passing that old saw around — one that Twain probably never actually said, by the way — is that it isn’t always cold in San Francisco. Far from it! “Summer” here is just around the corner, and the warm temperatures coming in September and October make up for all of the flaws of June.

While you may be looking forward to the heat, the rising mercury can be hard on your car. In addition to making sure that you have the right motor oil to stand up to warmer temperatures, you should also be aware that the summer heat can do a real number on your car battery, leaving you stranded if it can’t take the temps and gives up on you — even in balmy October.

How the Heat Can Shorten Battery Life

When the temperature rises, it disrupts the careful balance of chemicals inside your car battery. Fluid is key to your battery’s function, but when temperatures soar, all that heat causes some of the water in the battery to evaporate. This leaves your car battery off balance. What’s left of your battery fluid has less water but relatively higher concentrations of the chemicals that help it charge — and all that extra charging power makes your battery wear out much more quickly.

You might not notice it right away, but a simple battery check can keep you in tune with this important part of your car’s overall health so you can be proactive — instead of stuck waiting for a tow truck on your way to a big meeting.

Getting Your Car Battery Checked

As the hottest months of the year roll into the Bay Area, be sure to get your car battery checked. It’s fast and easy, and can save you a world of frustration down the road. A thorough battery check includes a visual once-over to look for and remove any dirt or corrosion.

Dirt will conduct extra energy and drain power from your battery, while corrosion will block the flow of energy, and both are bad! Some batteries can be topped off to keep the water evaporation from becoming an issue. We’ll also check to see that the electrical system in your car is charging at the correct rate. Remember that heat usually makes it charge too much, and this can reduce your battery’s life.

If your battery is being damaged by the heat, making adjustments or getting a new battery before it gives out completely will keep you on the road and out of the garage. We can help make that happen with our fast, dependable service, so stop by for a battery check while you’re out enjoying the amazing September weather!
