A lead-acid deep cycle battery is a battery designed to provide sustained power and operate reliably for a long period of time until the discharge reaches 80% or more, at which point it needs to be recharged. This type of battery is usually used in applications where deep discharge of the battery is required. 12 volt lead-acid deep cycle battery design floating life can reach 5~8 years. However, in actual use, due to a variety of factors, such as the use of inferior chargers, frequent overcharging, frequent undercharging, street fast charging, high-power discharge, quick stop, etc., the life of the battery may be greatly reduced. Many batteries are completely scrapped in 1 to 2 years in actual use. Therefore, the actual service life of a 12-volt lead-acid deep cycle battery will vary depending on factors such as its use conditions, environment, and user habits.

There is a direct proportional relationship between the depth of discharge (DOD) of lead-acid deep cycle batteries and the number of charging and discharging battery cycles that can be performed. The cycle life of the Battery is usually ten times that of the lead-acid battery. Its capacity is usually limited by the electrolyte capacity rather than the electrode mass, which helps to increase the average life expectancy. In general, lead-acid deep cycle batteries have an average life of six years, but they may last longer if kept at low discharge levels. The lead-acid deep cycle battery is a high-quality battery that is widely used in scenarios that require a long-term, stable power supply, such as Marine vehicles. For more information on lead-acid deep cycle batteries, it is recommended to consult the battery manufacturer or consult the professional literature in the relevant field.
