How does a battery separator work?

From powering our mobile devices to moving our vehicles, batteries enable us to do our daily routines. We all could not be doing this as safely and easily, without the battery separator.

Understanding the battery separator

A battery separator, although often overlooked, is an important part of any battery system with a starter- and an accessory battery (2nd battery). Its main purpose is to provide separation, whereby if the starter battery is not charged, the accessory battery is not connected. This seemingly simple role serves several crucial purposes:

  • Optimal charging: The battery separator ensures that the accessory battery is optimally charged.
  • Extending battery life: Battery separators maximize efficient battery usage, resulting in longer battery life (starter-and accessory battery).
  • Improving safety: Thanks to the battery separators, the starter battery will always be sufficiently charged so that the vehicle can be started safely.

Insulation Guard vs Ground Pin: The Advantages of Choosing an Insulation Guard


When it comes to ensuring the safety and reliability of electrical equipment, two crucial components often come into play: insulation guards and ground pins.

Both serve essential roles in electrical systems, but understanding their differences and advantages can help you make informed decisions for your specific applications. In this blog post, we will explore the benefits of choosing an insulation guard, focusing on the Samlex IG-25C, available at Samlex.

Insulation guard

What is an Insulation Guard? 

Before we delve into the advantages of an insulation guard, let’s clarify what it does. An insulation guard is an electrical accessory designed to provide an additional layer of protection against electrical shocks. It acts as a barrier between the electrical components and the user, preventing accidental contact with live parts. See our example: 

Insulation guard

The Advantages:

Enhanced Safety

The primary purpose of an insulation guard is to enhance safety. It prevents direct contact with live electrical components, reducing the risk of electric shock and other electrical accidents. 


Insulation guards are versatile and can be used in various electrical applications (such as the truck industry). They can be custom-fitted to different equipment and configurations, making them suitable for a wide range of industries and scenarios.

Compliance with Safety Standards

Many safety standards and regulations require the use of insulation guards to protect against electrical hazards. Using an insulation guard like the Samlex IG-25C ensures compliance with these standards, reducing the risk of legal liabilities.

Easy Installation

Installing an insulation guard is typically straightforward, and it can be retrofitted onto existing equipment with relative ease. This ease of installation minimizes downtime during implementation. Besides there is no need to install a time-consuming ground pin to secure safety.

Why Choose the Samlex IG-25C?

The Samlex IG-25C stands out as a reliable choice for enhancing electrical safety. It comes with the assurance of Samlex’s reputation for quality and innovation in the power electronics industry. Here are some additional reasons to consider the Samlex IG-25C:

Insulation Guard vs Ground Pin

In summary, while both insulation guards and ground pins play important roles in electrical safety, they have distinct purposes and functions. Insulation guards focus on preventing contact with live electrical components through electrical insulation, while ground pins ensure safe grounding by redirecting electrical faults to the ground. The choice between the two depends on the specific safety requirements and electrical system configurations in a given application.

Do you use a lot of power tools on site? Then an Insulation Guard is the better solution for your application.
