    Capacity and power ratings 

    • A battery’s capacity is the total amount of energy it can store, measured in kilowatt-hours (kWh). The power rating is the amount of electricity that a battery can deliver at one time, measured in kilowatts (kW). A battery with high capacity and low power rating will deliver a low amount of electricity for a long time. A battery with a low capacity and high-power rating can run an entire home or larger operation, but only for a few hours. 


    Depth of Discharge 

    • Most solar batteries need to retail some charge at all time due to their chemical composition and to prolong their lifespan. The DoD refers to the maximum of a battery’s capacity that should be used. For example, sealed lead-acid solar batteries are usually operated at  £ 50% DOD to achieve a reasonable cycle life, while lithium-ion batteries can operate at 80% DOD, 8kWh from a 10kWh battery, and still provide 5 years or more cycle life. 


    Round-trip efficiency 

    • Round-trip efficiency represents the amount of energy that can be used as a percentage of the amount of energy required to fully charge a battery. For example, if a 5kWh capacity battery, which delivers 4 kWh electricity, would typically require 110% to 120% times the 4kWh to be fully recharged. The battery has 80% to 90% in round-trip efficiency. One should, however, remember that the battery is part of the total system, and the system also has inefficiencies and energy losses. 


    Battery life and warranty 

    A battery’s ability to hold a charge gradually decreases the more it is used. For example, a battery might be warrantied for 5000 cycles or 10 years at 70% of its original capacity. This means that at the end of the warranty, the battery will have lost no more than 30% of its original ability to store energy. 

    Solar batteries come with warranties that guarantee a certain number of cycles and/or years of useful life. 

    This product has a 5-year warranty with a 10-year warranty option (refer to Rentech Lithium Warranty form)
