Features Of Trojan T31-AGM Battery


To provide optimum performance this T31 deep-cycle absorbed glass mat battery is packed with such design elements. This technology also makes this battery maintenance-free. As there is no hassle of changing acid water for AGM batteries

To absorb the electrolyte a hindrance of glass fiber is used to isolate the positive and negative plates when it functions as a bottler. To assure contact with plate surfaces the separator is maintained under compression between plates. 

Just a thing to keep in mind that trojan also makes the trojan T-31 overdrive model which is better in terms of performance compared to this. 


To provide high power density a computer-generated grid design is provided in this Trojan battery. The life cycles of the battery are extended through the robust plates of the system. Gas emission is reduced by the low calcium grid alloy along with flame arresting. Thus, the buildup of excessive pressure is prevented.  


Trojan T-31 is low-temperature tolerant and can easily handle shock and vibration. The main thing is it has a low internal resistance to make this all happen along with higher charging efficiency.

Advanced Technology

As the brand value itself secures the performance, durability, and reliability of this battery. A mere reflection would be that, they own almost all the batteries that are used on the golf carts over America. Therefore, their research in deep cycle batteries paves ways for innovation.

Features like Maxguard T2 Advanced Design separator, Trojan grid technology, T2 technology formulation, and Alpha plus paste are the most highlighted features of this battery. They help in providing a long-running time for this battery along with zero maintenance. This is the best part about these batteries in this entire Trojan AGM battery review. 

Though compared to the Trojan SCS150 this trojan battery is a bit on the heavier side with 69 pounds. Regarding low current, this 100 Ah battery is a great performer than others.

FAQs on Trojan AGM Batteries

In this portion of our Trojan AGM battery review, we’ll discuss some frequently asked questions on them.

How to maximize Trojan deep cycle battery life?

Always try to store your battery in a dry and cool place. Because if the temperature rises above room temperature then the battery life will decrease by about 50%. 

You should fully charge your batteries after use, even if you use them for a few minutes as well. If you store your battery with a low amount of charge then it might permanently damage the capacity and lifespan of your battery. If you are going to store your battery for long periods, make sure to charge them every 3 months. 

At a monthly rate of 5% to 15% lead-acid batteries tend to discharge, which hugely depends on the temperature of the storage. You should monitor the voltage of your battery considering its electrolyte to verify the full charging of the cells. Just as a reminder keep in mind that the total amps from your PV panel should be within 10 to 20% of the amp-hours of the whole battery pack. 

What to consider before buying deep cycle AGM batteries?

The cycle life of a battery is the most important thing to consider while buying a deep-cycle battery for renewable energy applications. This is the count of discharge a battery provides in its lifespan. Before reaching a certain point where the battery is unable to operate this is the point. 

Batteries of identical weight, design, process, materials, and quality might seem equal but the main difference between them is quality control. Due to difference in quality control, the lifespan of batteries differ hugely, thus the battery discharging cycle is affected. If you compare two batteries of the same Ah and if one of them have 1000 cycles discharge and another has 500, then the prior one is half the lifetime cost of the later one. 


Trojan has been a pioneer in manufacturing innovative batteries for more than 90 years. These AGM batteries are all maintenance-free batteries. You can simply maintain them with limited care and they will provide excellent performance in years to come. Hope our Trojan AGM battery review was helpful enough for you to choose the best one for you.
