How Long Does a 36V Lithium Marine Battery Last?

Boat owners and outdoor enthusiasts often use 36V lithium marine batteries because they're lightweight, powerful, and long-lasting. However, many people still wonder how long these batteries last. Here, we'll explore all the factors that affect the life span of a 36V lithium marine battery, from the type of battery to its usage and maintenance. Keep reading to find out how long a 36V lithium marine battery can last.

What Is a 36V Marine Battery Used For?

A 36V lithium marine battery is a rechargeable battery that powers electric boats, trolling motors, and other outdoor equipment. These batteries have a life span of 5–7 years, depending on how well they are maintained. However, several factors can affect their longevity, such as the type of battery, its capacity, usage, and maintenance.

Types of Lithium Marine Batteries

The type of battery is crucial because it determines the technology used to make the battery. A lithium iron phosphate (LiFePO4) battery is the most durable and long-lasting type of lithium marine battery. It can last up to seven years with reasonable care and maintenance. On the other hand, lithium polymer (LiPo) batteries are less durable and last up to five years.

Understanding Capacity

The capacity of the battery also affects its life span. The higher the capacity, the longer the battery will last. For instance, if you have a 36V lithium marine battery with a 100Ah capacity, it can last up to 20 hours. However, discharging it more than 80 percent will reduce its life span, resulting in a charge that lasts only a few hours. Therefore, it's crucial to use the battery wisely and avoid over-discharging it.

Proper Use

The frequency and duration of usage determine how long the battery lasts. If you use your 36V lithium trolling motor battery for short periods and charge it immediately after use, it will have a longer lifespan. However, if you discharge it completely and leave it for an extended period, its life span will reduce significantly. Therefore, the frequency and duration of usage affect the battery's overall life.

Maintenance and Care

Finally, maintaining the 36V lithium marine battery ensures its longevity. Regular maintenance practices such as cleaning the battery, checking its charge level, and avoiding overcharging will prolong its life span. Also, charging the battery with the correct charger and temperature range will prevent damage caused by overcharging or overheating.

Get the Most Out of Your Cell

How long a 36V lithium marine battery lasts depends on several factors. It's essential to choose the right type of battery, use it wisely, and maintain it regularly to ensure its longevity. By following these simple tips, you can enjoy your 36V lithium marine battery for many years to come.
