Ultimately, the best way to determine how long your 12-volt marine battery will last is to consult your owner’s manual or contact the manufacturer directly. There are a few things to consider when deciding if a deep-cycle marine battery is a right choice for your solar needs.
How Long Can a Deep Cycle Battery Last Without Charging?
A deep cycle battery is designed to last for a long time without charging. However, how long it will actually last depends on a number of factors, including the type of battery, the quality of the battery, how it is used, and how well it is maintained. The most important factor in determining the lifespan of a deep-cycle battery is the type of battery.
There are two main types of batteries used in deep cycle applications: lead-acid and lithium-ion.
| Lead-acid Batteries | Lithium-ion Batteries |
| Lead-acid batteries are typically cheaper and have a longer lifespan than lithium-ion batteries. However, they are also heavier and require more maintenance. | Lithium-ion batteries are lighter and require less maintenance, but they are more expensive and have a shorter lifespan. The quality of the battery also plays a role in how long it will last without charging. A higher quality battery will typically last longer than a lower quality battery. |
| This is because deeper discharges put more stress on the Battery cells and reduce their overall life expectancy. It’s important to note that even if you only discharge your Battery to 80%, you should still aim to recharge it before it drops below 50% to help prolong its life span. Another way to help prolong your Battery’s life span is by equalizing charges. | This is because higher-quality batteries use better materials and construction techniques that allow them to withstand more wear and tear. How the battery is used also affects its lifespan. If the battery is regularly discharged below 50%, it will likely not last as long as one that is only discharged to 80%. |
| All things considered, a good rule of thumb for most people would be anywhere between 3-5 years for lead acid Batteries | All things considered, a good rule of thumb for most people would be anywhere between 2-3 years for lithium-ion Batteries. |
How Long Does a Marine Battery Last on a Trolling Motor?
If you’re a fisherman, you know that having a reliable trolling motor is crucial to a successful day out on the water. But how long does a marine battery last on a trolling motor? Let’s take a look.
A typical marine battery will last anywhere from 8 to 12 hours on a single charge when used with a trolling motor. However, there are many factors that can affect this number, such as the speed at which you’re running the trolling motor and the type of battery you’re using. For example, if you’re using a lead-acid battery, you’ll likely get less run time than if you’re using a lithium-ion battery.
And if you’re constantly running your trolling motor at high speeds, your battery will drain more quickly than if you were just cruising along slowly. In general, though, most fishermen can expect to get around 10 hours of use out of their trolling motors on a single charge. So if you’re planning an all-day fishing trip, be sure to bring along an extra marine battery or two just in case!
