How long do marine batteries last.

The service life of marine batteries is usually 2 to 10 years, depending on the type and maintenance of the battery. Marine batteries are mainly divided into two types: lead-acid batteries and lithium-ion batteries. Lead acid batteries are a widely used type of marine battery, with a service life typically of 2 to 5 years. However, improper use and maintenance may shorten the lifespan of batteries, and common influencing factors include overcharging and discharging, high temperatures, and long charging times. In contrast, lithium-ion batteries have a longer lifespan, typically up to 8 to 10 years. Lithium ion batteries have the characteristics of high energy density, lightweight and portability, but their prices are relatively high.

In addition, pure electric ships have just started, and the theoretical service life of marine power batteries is 8-10 years. However, this theoretical service life has not been verified yet, and its energy attenuation also needs to be verified through actual operation. Therefore, the actual service life of marine batteries may vary due to factors such as battery type, usage conditions, and maintenance. ‌
