Battery life:

We divide life into years and discharge cycles. GEL and AGM batteries have a service life of 8 to 15 years. This is suitable for buffer work (UPS installation) with an ACID of about 5 to 8 years. These parameters are important for UPS systems and are important for marine engines for renewable energy sources such as photovoltaic panels, wind turbines, and circulation. The cycle life parameter is more important and it significantly reduces battery life. A good GEL, the AGM battery has a cycle life of 900 cycles at 50% discharge, and the same battery at 70% discharge has only about 350 cycles. Please note that the previous work cycle has only 60% battery capacity. There are also enhanced models to choose from, with more cycles and shorter battery life, so it's worth checking out the quotes and parameters. For ACID batteries, this life is typically 500 cycles, but there are also enhanced versions with a large number of cycles. It is worth remembering that the battery capacity of the first cycle will never correspond to the last cycle. If we use the battery twice a week for 6 months, we will consume about 60% per year. In theory, 80% of the battery discharge time is less than 6 years, but! After 4 years, the capacity will be much smaller and the capacity will be shortened at the end of 2 years. With this option, we increase the capacity by 50% more than planned, and we will offload up to 50%, so we will extend the cycle life and will still have capacity in the sixth.
