 A Brief Intro Of The Trojan t105 And Why You Should Get The Right Charger

Since the company’s inception over 90 years ago, the Trojan batteries have been known to be one of the best in terms of deep-cycle batteries. One of its selling points has been the portability, as well as its unique amperage that has made it stand out amongst its several competitors. The Trojan t105 batteries are fully charged upon purchase, which is something you don’t really get from other brands. 

Anyone with a large budget would agree with me when I say that the Trojan t105 is worth every penny, and it’s only right that you get the right and proper charger for your Trojan t105. Here are some other reasons and benefits that should make you get only the best charger for your Trojan t105, or other deep-cycle batteries.

Pro Tips Of Getting The Right Battery Charger

Increases The Battery Life Of Your Deep-Cycle Batteries

This is probably one of the best reasons you should consider getting only the right charger for your Trojan t105 and other deep-cycle batteries – using the right charger for your battering will only prolong the lifespan of your deep-cycle batteries, thereby improving the output and performance of your Trojan t105. Everyone wants good value for money spent, and getting the right charger is definitely the way to go. (Read Also: 4 Best Car Battery Charger For Electrolysis In 2022)

Saves Time To Charge

Getting the right charger for your Trojan t105 deep-cycle battery is synonymous with getting your battery charged in good time. Knowing how valuable time is to us, you wouldn’t want to waste time waiting on your battery to sufficiently charge due to a poor charger – a slow charger is usually more expensive than the right charger being that it consumes more time.

Prevents The Battery From Sulfating

Sulphating is a phenomenon that occurs when a battery sits too long without appropriately charging it. This can reduce the battery’s overall performance, or even damage the battery entirely, and a bad battery charger can be rightly blamed due to the battery not charging to its full potential thereby causing it to go flat frequently.   

Why You Should Replace Your Old Charger With The Newer Models

Going with the advent of technology, you would be greatly mistaken if you feel your old chargers will suffice for the new and improved Trojan t105 in the market today. These new batteries come with some enhancements your old chargers won’t be able to handle adequately. Here are three reasons getting a new charger for a new Trojan t105 would be a smart move on your part:

Power Supply Duties

Owing to the improvements in new and modern batteries a minimum voltage should be maintained all the while you charge the battery, and the only way this can be possible is if you use the modern-day charger.

This feature is lacking in the old chargers as you happen to find old chargers charging beyond the intended capacity of the battery – research shows that chargers made at least 7 years back are guilty of this defect. (Read Also: 4 Best Battery Charger For Jeep Wrangler In 2022)

Temperature Controls

Using your smartphone as an example, you will notice that it charges sower at higher surrounding temperature, and faster at lower temperatures – this feature is to ensure that your battery doesn’t overheat – the same is needed for your Trojan t105 battery, and older chargers do not have the feature of regulating the charging input of your battery which could lead to overcharging. Modern-day chargers are equipped to regulate the charge input based on the immediate temperature.

Newer Chargers Handle Float Conditions

Have you ever wondered what happens to your battery cells once it charges to maximum? Well, nothing much, but it could harm the overall lifespan of your battery if you make it a habit. But this wouldn’t be a problem if you used the newer chargers which are designed to float the current in such a way that it doesn’t affect your battery life span in any way. The older chargers on the other hand do not have such uniqueness to their build.   

So don’t get a new battery charger because the older charger isn’t charging your battery as it should, get it because it would do a better job in the long run. (Read Also:Does Bluetooth Keyboard Drain Battery?)

Factors To Consider Before Buying A Battery Charger For Your Trojan t105 Charger – Buyers Guide

Here are some factors you should consider before buying a charger for your Trojan t105 battery:

End Of Charge Control

As I pointed out earlier, the “end of charge control” is one major difference between old-fashioned chargers and the new ones we have in the market today.

Avoid any charger that doesn’t have the end of charge control, because excess charging current will ruin a battery in no time. A charger should stop charging your battery as soon as the battery gets fully charged. Ensure you notice this feature before making your purchase.

Low Charging Capabilities

A common feature of bad chargers is their low charging capabilities. As I earlier pointed out, chargers with low charging capabilities are more likely to ruin your batteries than prolong their lifespan, so ensure you look out for chargers with at least moderate capabilities in terms of speed and current output.

Environmental Considerations

What area are you likely to use your battery charger? Will it be exposed to harsh weather conditions such as damp or dusty environments? Or hot weather conditions? Having an idea of where you intend to use your charger should guide you on the sort of battery charger to purchase. Buying chargers that are built with hermetic seals will be an advantage in such situations.

Vibration Requirements

If you work in areas where vibrations are bound to happen from time to time, such as ships or industrial areas, then you might want to consider getting battery chargers that are encapsulated. The covering of an encapsulated charger prevents the external part of your battery charger from moving of their own accord thereby preventing any sort of failure.

Fan Characteristics

Obviously, you would need a battery charger built with fan cooling properties especially if you intend to use it in a hot environment. However, there are certain things associated with purchasing a fan-designed battery charger, and some of them are as follows;


Getting a charger built with a fan will mean that the charger won’t be bulky, thereby saving space where required.(Read Also:6 Best 9V Battery For Bass Guitar In 2022)

Overheating can never be a problem for these sorts of chargers.

It has a greater power output of up to three times when compared to conventional cooling chargers.

The fan helps to reduce component temperatures which helps to reduce the mean time between failures (MBTF), and also increases the reliability in the process. (Read Also: Can You Use A Car Battery For Electrolysis?)


Fan-built chargers can be a nuisance in areas that require tranquillity or quiet due to the noise they produce.

Dust and some other contaminants are likely to be drawn into the charger. 

Of all the parts of the unit in the charger, the fan is the least reliable. Don’t depend on it to go the extra mile like your battery charger.

You need to regularly clear the air filters of a fan-built charger, which can be quite a burden if you are pressed for time.

Electrical Considerations

What is the battery size of your battery? For instance, if your battery size is a 24V battery system that comprises 12V batteries connected in series, then you can use a single 24V unit charger which should suffice. But ensure you don’t charge the batteries individually as it will overload the battery.

Having known all these, I carried out some research based on persons who owned a Trojan t105 battery, and the charger that was suitable for their batteries, and I was able to come up with three interesting choices based on their opinions in sites discussions. These chargers have their own pros and cons, but based on popular opinion and reviews, you can be certain that they will serve their purpose – whether you are using a Trojan t105 battery or any similar deep cycle battery.
