Interstate

Interstate batteries are made in the US to an excellent standard. They are good quality standard "wet" batteries. The smaller SRM range are dual purpose (deep cycle and starting) and are a great choice for marine or RV. Interstate batteries also can handle the heat under the bonnet of turbo diesel vehicles and work well for dual batteries installations.
The Workaholic range from Interstate are designed for deep cycle applications in golf carts or solar installations. They can be used as drop-in replacement for Trojans and will typically outperform the equivalent Trojans by a sizeable margin.
