Plus, the low self-discharge means I can store it for weeks without losing much capacity, which is a big plus for backup power or off-grid projects.

On the downside, the price is a bit steep compared to some other lead-acid options, especially since it’s a two-pack. Also, while maintenance-free, I’d still recommend periodic checks—just to keep everything running smoothly.

Overall, it’s a dependable choice for anyone needing extended power in demanding environments.

Imagine opening the battery compartment of your RV and realizing the Trojan T-105 is surprisingly lighter than you expected for a 62-pound beast. I was prepared for a hefty weight, but this one feels more balanced, making handling a bit easier during installation.

The first thing that caught my eye was how compact these six batteries look lined up side by side. With dimensions just over 10 inches in length and about 7 inches wide, they fit snugly in most battery trays.

The 18-month warranty offers peace of mind, especially considering the price for six units. For anyone needing a reliable, versatile energy source, these Trojan T-105s are a solid choice.

Of course, they are heavy, so plan your install accordingly. And being flooded/wet lead-acid, maintenance involves checking water levels periodically.

Still, their performance and durability make the extra care worthwhile.

The price is fair considering the capacity and durability you get—this isn’t some throwaway battery.

However, keep in mind that it doesn’t come with a wire harness or mounting hardware, so you’ll need to plan for that. Also, while it’s versatile, it’s primarily lead-acid, so it’s not as lightweight or long-lasting as lithium options.

Still, for those who want a dependable, maintenance-free deep cycle battery, this one checks many boxes.
