FAQs

Is there a difference between deep cycle and marine battery?

Yes, there is a difference between deep cycle and marine batteries. Deep cycle batteries can be entirely drained and recharged many times over, where as cranking batteries can't. Deep cycle marine batteries are much less likely to overheat since their thicker plate construction can withstand high temperatures better.

How many years does a deep cycle marine battery last?

The average lifespan of a deep cycle battery is about 3-6 years. However, the lifespan of a deep cycle battery will vary based on several factors such as the type of battery, how it is used and maintained, and the climate in which it is kept. Some deep cycle batteries may last up to 10 years with proper care and maintenance.

Can you use a marine battery as a deep cycle battery?

While marine batteries are dual-purpose and can work as both a starting battery and deep cycle battery, they're not ideal for large RVs or boats. Deep cycle batteries are designed to be discharged and recharged repeatedly, while marine batteries are designed for occasional discharge. If you're using a marine battery as a deep cycle battery, it won't last as long as a true deep cycle battery.

What does MS stand for on a marine battery?

A marine starting battery is a battery that is designed to start the engine of a boat. It is important to note that a marine starting battery is not the same as a marine deep cycle battery. A marine starting battery typically has a higher cranking amps rating than a deep cycle battery, and is designed to be discharged and recharged on a regular basis.

How good are DieHard marine batteries?

The DieHard marine battery is an excellent choice for anyone who needs a reliable and powerful battery. Its 780 CA rating means that it can provide plenty of power for your boat, and its MCA rating is very close to that, making it a great choice for cold weather boating.
