The US Battery US1800XC2 set of 6, each with a capacity of 208 Ah, is a solid choice for various applications like RVs, golf carts, and solar systems. These batteries belong to the BCI Group GC2 and are built as flooded lead-acid types, which are known for their reliability and long cycle life.

With a weight of 58 pounds each, they are quite heavy, which might be a consideration if weight is a concern for your setup. However, their deep cycle capabilities mean they can handle multiple charging and discharging cycles effectively, making them suitable for long-term use in demanding environments.

They offer impressive capacity minutes—392 minutes at 25 amps and 107 minutes at 75 amps—ensuring that they can sustain significant loads for extended periods. The batteries are designed for vehicle-specific fitment and have molded-in UTL terminals for secure connections. They are produced in the USA, and one potential downside is their size (10.25).

The US Battery US2200 XC2 comes as a pack of four 6-volt batteries, each offering a substantial 232 amp hours of power. This makes them a strong option for RV owners needing reliable, long-lasting power. The batteries are a good replacement for the popular Trojan T-105 batteries, ensuring compatibility with existing setups.

With dimensions of 10.25 x 7.125 x 11.25 inches, they fit the standard GC2 group size, which is common in many RVs. The molded-in UTL terminals and polypropylene heat-sealed cases contribute to their durability and reliability. Weighing in at 62 pounds each, they are on the heavier side, which might be a consideration for some users in terms of handling and installation. However, their solid construction promises longevity.

The pack includes a 2-year warranty, providing peace of mind regarding their performance. If you're looking for a high-capacity, robust option for your RV power needs and are willing to overlook the relatively higher weight, the US Battery US2200 XC2 could be a great choice.

The Trojan T-605 is a 6-volt deep cycle battery offering a robust 210Ah capacity, which makes it suitable for RVs and other demanding applications like golf carts and renewable energy systems. Its deep-cycle nature means it can be discharged and recharged many times, an essential feature for RV use where consistent energy supply is needed over time.

One of its main strengths is its size and capacity balance; being part of the GC2 category, it fits well in spaces designed for standard golf cart-style batteries. Despite its relatively compact dimensions (10.3 x 7.11 x 11.07 inches), it delivers significant power storage, which is a positive for RV owners needing reliable energy for extended trips.

However, this battery is on the heavier side, weighing 58 pounds, which could pose a challenge during installation or if frequent repositioning is necessary. Its lead-acid composition means it requires regular maintenance, such as checking water levels and ensuring it’s adequately charged, which might be cumbersome for some users. Additionally, flooded lead-acid batteries are not as tolerant of extreme temperatures as some other types, so it might not be the best choice for those who travel in very hot or cold environments.

The charging time isn't specified, but typically, lead-acid batteries take longer to charge than lithium alternatives, which could be a drawback if quick turnaround is needed between charges. Despite this, users report high satisfaction with the battery's performance, as evidenced by its strong customer ratings, indicating reliability and longevity if maintained properly. The Trojan T-605 is a solid choice for those who need a powerful and standard-size battery for an RV, provided they are prepared for the upkeep and weight considerations.
