10 Best Deep Cycle Battery For Dump Trailer 2025 in the United States

The Trojan T875 is an 8-volt, 170 Ah deep-cycle battery designed primarily for applications like golf carts, RVs, and renewable energy systems. One of its main strengths is its robust capacity of 170 Ah, which allows for extended use before needing a recharge. This makes it particularly suitable for those who rely on consistent power supply over longer periods, such as in off-grid solar setups or for recreational vehicles on long trips. Its durability is also notable; Trojan batteries are known for their cycle life, meaning they can be discharged and recharged many times without significant degradation in performance, making them a solid investment for anyone needing reliable energy storage.

On the downside, being a flooded/wet lead-acid battery means it requires regular maintenance to ensure optimal performance and longevity. Users must keep an eye on the fluid levels and ensure proper charging practices to avoid damage. Additionally, at 63 pounds, the T875 is relatively heavy, which could be a consideration for those who need to transport it frequently or fit it into tight spaces. Its dimensions (10.27” x 7.10” x 11.14”) adhere to the common GC2 size, making it compatible with many existing setups, but this bulk could be a drawback for smaller applications.

Temperature tolerance is another factor; while lead-acid batteries typically perform well in moderate conditions, extreme temperatures can impact their efficiency. Users in particularly hot or cold climates may need to consider this carefully.

The Renogy Deep Cycle AGM Battery offers a solid 12V 200Ah capacity, making it well-suited for powering dump trailers and similar equipment that require steady, reliable energy over long periods. Its AGM (Absorbent Glass Mat) design means it’s maintenance-free—no watering or acid handling—which is convenient for hassle-free use. The battery features a low self-discharge rate of about 3% per month, so it holds charge well even if not used frequently. It supports high discharge currents, useful for jump-starting or demanding power draws, and handles a wide range of temperatures, performing reliably even in cold weather (below freezing).

In terms of size and weight, it’s quite hefty at nearly 128 pounds and about 20 inches long, so consider space and mounting options on your trailer. The battery should last for many charge-discharge cycles if used properly due to its design and materials. One limitation is that it should be installed upright to avoid damage, which might restrict placement flexibility.

This Renogy battery provides a dependable, low-maintenance power solution for dump trailer owners, especially those needing a robust battery capable of withstanding varying climates.

The Interstate Batteries 12V 100Ah 31M-AGM Marine/RV Battery is designed as a dual-purpose battery, meaning it can both start engines and provide steady, long-lasting power for accessories. This makes it a good choice for those needing reliable deep-cycle performance for dump trailers, boats, or RVs. It uses pure lead AGM technology, which offers a longer life—about two to three times that of typical AGM or flooded batteries—and faster recharging.

The battery capacity of 100Ah is solid for extended use, and its design with thick plates supports frequent deep discharges without quickly wearing out. At 72 pounds and roughly 13 x 7 x 9.5 inches, it’s a bit heavy and bulky, so handling and fitting should be considered. Maintenance is low since AGM batteries are sealed and don’t require water refilling.

If you're looking for a tough, long-lasting battery that can handle both cranking and deep-cycle needs on your dump trailer or similar equipment, this Interstate model is a trustworthy pick, especially if you prioritize lifespan and maintenance ease over weight.
