A deep-cycle battery is built to deliver steady power over a long period and handle repeated discharge/charge cycles, which makes it a go-to choice for marine setups, RV accessories, and other applications where you’re powering loads for hours instead of just starting an engine.
Not sure which deep cycle you need? Call 905-549-4454 or email ordersGNB@gocbs.com with your application and current battery code.
You charge a deep-cycle battery best with a quality multi-stage (“smart”) charger matched to the battery type (flooded vs AGM), then you recharge as soon as possible after use and avoid chronic undercharging, since proper staged charging is the safest way to reach full charge and support longer service life.
AGM is a battery design (Absorbent Glass Mat) and deep cycle is a battery job, so some AGM batteries are true deep-cycle units while others are built mainly for starting or dual-purpose use—if you need deep-cycle performance, choose a battery specifically labeled for deep-cycle service.
Deep-cycle battery life depends heavily on how deeply you discharge it, how well it’s charged, and heat exposure, because deeper discharges and poor charging habits reduce overall cycle life—if you tell GNB what you’re running (boat, RV, etc.) and how often, they can help you choose the right size so you’re not shortening lifespan by under-sizing.
