The most common type of battery used in home energy storage systems is lithium-ion batteries. They are favored for their high energy density, long lifespan (up to 20 years), and fast charge/discharge times2. Lithium-ion batteries account for about 90% of the global grid battery storage market2. Other types of batteries used include lead-acid and flow batteries, which have their own benefits and drawbacks3.For example, lead-acid batteries are less expensive but have a shorter lifespan compared to lithium-ion3.

Rated power capacity is the maximum power that the battery can provide in ideal conditions. It is provided by the battery manufacturer and typically measured in kW. A higher rated power capacity means that the battery can provide more power and can be used for a wider range of. .
Energy capacity is the maximum amount of energy that the battery can store. It is typically measured in milliamps × hours (mAH). For example,. .
The storage duration is the amount of time that the battery can store energy without being recharged. It is typically measured in hours and is a good indicator of how long the battery can. .
Self-discharge is the rate at which a battery loses its charge when it has not been used for some time. A lower self-discharge rate means that the battery can be stored for longer. .
Cycle life/lifetime is the number of times that the battery can be charged and discharged before it needs to be replaced. It is typically measured in cycles and the number of years that. In summary, the key characteristics of BESS are rated power capacity, energy capacity, storage duration, cycle life/lifetime, self-discharge, state of charge, and round-trip efficiency. [pdf]
