什么是深循环电池？

Deep cycle batteries are a type of rechargeable battery designed for long-term, continuous use. Unlike regular car batteries which provide a short burst of high energy, deep cycle batteries are built to provide sustained power over extended periods of time.
深循环电池是一种专为长期、持续使用而设计的可充电电池。与提供短时间高能量输出的普通汽车电池不同，深循环电池旨在长时间提供持续的电力。Deep cycle batteries are an essential component for powering recreational vehicles, boats, golf carts, and other off-grid applications. With a wide range of brands and types available in the market, it can be overwhelming to choose the right deep cycle battery for your specific needs.
深循环电池是为房车、船只、高尔夫球车及其他离网应用供电的关键部件。市场上品牌和类型繁多，为您的具体需求选择合适的深循环电池可能会让人感到无从下手。
 

‌深循环电池是一种能反复深度放电（通常 80% 以上）并充电的电池，主打耐用和稳定供电 。‌‌‌‌

1. ‌放电方式‌：启动电池是瞬间爆发大电流，深循环电池则是细水长流，能长时间持续供电 。
2. ‌内部构造‌：深循环电池极板更厚，活性物质密度高，更耐折腾，寿命更长 

常见于房车、船舶、太阳能储能系统，还有电动工具和叉车等需要持续电力的设备 。‌‌百科‌

1. ‌铅酸电池‌：包含胶体、AGM 等，技术成熟，价格较低，但重量大 。
2. ‌锂电池‌：如磷酸铁锂，更轻、循环次数更多，铅酸通常几百次循环，锂电可达几千次 。‌‌‌
