As a car owner, I have always been mindful of the maintenance and safety of my vehicle. One important aspect that I have learned over the years is the need for a 12 volt battery disconnect switch. This small yet crucial device has proven to be a lifesaver on numerous occasions.

Firstly, a 12 volt battery disconnect switch allows me to easily disconnect the battery from all electrical connections in my car.

A 12-volt battery disconnect switch is an electrical device that allows you to cut off the power supply from your car’s battery. It is usually installed between the battery and the rest of the electrical system, and it can be manually turned on or off. This switch is commonly used in vehicles with multiple batteries or in situations where the vehicle will be parked for an extended period.

Why Do You Need a 12 Volt Battery Disconnect Switch?

There are several reasons why you may need a 12-volt battery disconnect switch:

1. Safety: A battery disconnect switch can prevent accidental electrocution when performing maintenance tasks on your vehicle’s electrical system.

2. Prevent battery drain: If you’re not going to use your vehicle for an extended period, a battery disconnect switch can help prevent the battery from draining and prolong its lifespan.

3. Anti-theft: Installing a battery disconnect switch makes it difficult for thieves to start your car since they won’t have access to power from the battery.

4. Easier troubleshooting: A 12-volt battery disconnect switch allows you to isolate different parts of your car’s electrical system, making it easier to troubleshoot any issues that may arise.

Types of 12 Volt Battery Disconnect Switches

There are two main types of 12-volt battery disconnect switches – manual and remote-controlled switches.

1. Manual switches require physical contact with the switch itself to turn it on or off.

2. Remote-controlled switches allow you to turn off the power supply from a distance using a key fob or other remote control device.

4. Quality: Invest in a high-quality switch from reputable brands as it will last longer and provide better performance.

5. Installation: Some switches may require wiring while others can be installed without any special tools or skills. Choose one that you are comfortable installing yourself or get professional help if needed.

Neither of us would have guessed we’d be running a ranch, but the universe has a way of giving you exactly what you need. Ranch life is demanding, but it’s our creative playground.

As yogis and meditators, we strive to emit balanced and loving energy. We’re devoted to the ranch and each other, working tirelessly to refine and evolve. Our heart and soul go into cultivating space for ease and joy.

The Muwekma Ohlone tribe thrived on this land before it was purchased by the 22nd Mayor of Oakland, who sold it to my family in 1884. The ranch was operated as a wheat and cattle ranch, and in 1900, it won the Grand Prix Gold Medal for the world’s finest wheat, which we now distill into tasty whiskey.

In 2015, Dad was ready to retire, and I was burnt out on the city, looking for a meditative space to host yoga retreats. So, I took the leap and met Albe two months later. How serendipitous! Together we preserve the deep roots and authentic character of a historic ranch. Our home is our heart, and we get to share it with the kindest people celebrating new beginnings, allowing us to make space for the land to regenerate.
