Why I Converted My Top Battery Post to Side Post: A First Person Experience

As a car owner, I have always been concerned about the maintenance and performance of my vehicle. One issue that I encountered with my car was the frequent corrosion and damage to the top battery posts. This not only affected the functionality of my battery but also posed a safety hazard. After consulting with my mechanic, I decided to convert my top battery posts to side posts and it turned out to be one of the best decisions I made for my car.

One of the main reasons why I converted my top battery post to side post was because it eliminated the issue of corrosion. With side posts, there is a lower chance of acid leaking onto the terminals and causing corrosion. This not only extends the life of my battery but also saves me from having to replace it frequently.

Another advantage of side post conversion is that it makes it easier to connect and disconnect the battery. With top posts, I had to struggle with tight spaces and sometimes even remove other components just to access them. However, with side posts, all I need is a simple wrench and I can easily connect or disconnect the battery without any hassle.

Moreover, converting to side posts also improved the overall appearance under the hood

My Buying Guide on ‘Top Post To Side Battery Post Conversion’

As a car enthusiast and mechanic, I have come across many different types of battery posts and conversions. One that has stood out to me is the top post to side post conversion. This type of conversion allows for easier access to the battery terminals and can also prevent corrosion buildup. In this buying guide, I will share my personal experience and provide some tips for purchasing the best top post to side post conversion.

What is a Top Post to Side Post Conversion?

A top post to side post battery conversion involves changing the type of battery terminal connections on your car’s battery. Top post terminals are the traditional type where you have a positive and negative terminal that stick up from the top of the battery. Side post terminals, on the other hand, are located on the side of the battery. The conversion involves replacing your top post terminals with side post terminals.

Benefits of a Top Post to Side Post Conversion

One of the main benefits of this type of conversion is ease of access. With top post terminals, it can be difficult to reach them in tight spaces or if your car has a lot of engine components blocking access. Side post terminals are easier to reach and can save you time and frustration when trying to jumpstart or replace your battery.

Another benefit is preventing corrosion buildup on your battery terminals. Top post terminals are more prone to corrosion due to their exposed position on top of the battery. By converting to side post terminals, you eliminate this issue as they are protected by the sides of the battery case.

Things to Consider Before Purchasing

Before making any purchase, it’s important to consider a few things:

– Compatibility: Not all cars are compatible with this type of conversion. Make sure to check if your car’s make and model is suitable for a top post to side post conversion.
– Quality: As with any product, it’s important to invest in good quality materials for safety and durability reasons.
– Installation: While this conversion can be done at home with basic tools, it may require some knowledge about car batteries and electrical systems. If you’re not comfortable doing it yourself, it’s best to seek professional help.

Tips for Choosing the Best Top Post To Side Battery Post Conversion

Here are some tips that I have learned from my experience when choosing a top post to side post battery conversion:

– Look for reputable brands: Stick with well-known brands that have good reviews from other customers.
– Check material quality: Look for high-quality materials such as copper or brass as these will ensure good conductivity.
– Consider additional features: Some conversions come with additional features such as protective covers or built-in fuses which can be beneficial for added safety.
– Compare prices: Don’t just settle for one option, compare prices from different brands and choose one that fits your budget without compromising quality.

Conclusion

In conclusion, investing in a top post to side post battery conversion can make car maintenance easier and prevent potential issues such as corrosion buildup. Before making a purchase, make sure it’s compatible with your car model, invest in good quality materials, and consider seeking professional help if needed.
