We have already told you on occasions that the car battery is the element of the vehicle to start the car with tweezers, but when it starts to give problems, in most cases, you have to end up changing the battery.
The less effort you have to make the battery, especially when it approaches the end of its useful life, the better. Avoid starting the car with the lights on, the radio running, or air conditioning connected.
Nothing started with the engine stopped
Some modern cars already warn you if you turn the radio on with the engine stopped, warning that the battery can discharge. Also, avoid leaving car lights including interiors. In one night you can take a dislike.
Monitor extreme temperatures
It is common for the battery to drain without warning with extreme cold, but very high temperatures do not feel good either. Whenever possible, do not leave the car outdoors for several hours at temperatures below 5º C or above 35º C.
Eye with external electrical equipment
If you want to install audio equipment or external lights different from the standard ones, be sure to do it well or hire a reputed professional. If the connections are not well insulated, with the engine stopped, small discharges will occur that will drain the battery early. Depending on what you install, it may be advisable to install a higher power battery, inform yourself.
In cars that have already turned a few years, a white crust may form on the terminals. To remove it, use a metal brush, water, and baking soda. You will avoid changing the battery early.
A car stopped too long
Those who use the car from time to time, especially when the battery already has time, will have verified that it can completely discharge. Ideally, start the car at least once a month and travel 30 or 40 kilometers by road or highway.
