Deep Cycle Batteries buying guides

Deep cycle batteries are built to give steady power for a long time and be drained far down, unlike a car starter battery that gives a short burst. That makes them the usual choice for trolling motors, RVs, boats and off-grid setups. Look at capacity, which tells you how long it runs, and the chemistry, such as flooded, AGM or lithium. Each has its own upkeep and weight.
