VMAX V28-800S Battery Cross-Reference
The V28-800S features an efficient internal design that increases capacity to 28Ah while maintaining the same case size as many lower-capacity SLA batteries. Unlike most standard general-purpose SLA batteries in this size, the V28-800S is a true deep cycle battery, providing improved performance and a longer battery lifespan. If you need extended run time or the addition of deep-cycle durability without the space for a larger battery, this is an ideal solution.
