Charge It in St. Johns for Extended Battery Life

October 1, 2022

Here's an interesting statistic for our in St. Johns , Florida, drivers: Only 30 percent of car batteries make it to 48 months. And the life expectancy varies by where you live. It ranges from 51 months in extremely cold areas to just 30 months in extremely hot climates.

Why is that? It turns out that it's our modern cars with all their electric accessories that are to blame. Things like, GPS, DVDs and entertainment computers are keeping vehicle batteries from maintaining a full charge. The longer a battery goes with a low charge, the sooner it'll die.

It's clear that you St. Johns drivers need to recharge your batteries. This is the job of the alternator. The problem comes when the car's demand for electricity is high and we are driving in stop and go conditions or short trips around St. Johns . The alternator just can't keep up.

The result is shortened battery life. So what can we do to improve our battery's health?

We need to keep the battery as close to a full charge as possible. That can be hard because sitting for just 24 hours in hot weather between charges can be too long. When the weather's cold in St. Johns , sitting for several days will cause discharge.

So some highway driving around Florida will help keep a full charge if the battery has not been deeply depleted. Car batteries are not designed to be run down really low, or deep cycled, as it's called. So using your headlights or other power accessories when the car is off can deeply deplete your battery. Using the alternator to recharge from a deeply depleted state is also very dangerous to your battery because it charges too fast. In fact, on average, your battery would only last for ten recharges like that.

If you do find yourself with a dead battery or very low battery, use a good quality battery charger to slowly bring the battery up to full charge. Follow the instructions on the charger or talk to your friendly and knowledgeable service advisor at Tuffy St. Johns .
