What type of battery is used in a typical 2kVA UPS?

Most 2kVA/2kW UPS use a valve regulated lead acid (VRLA) maintenance free battery with a 5year design life. Some 2kVA UPS are available with lithium-ion batteries with a 10year design life. Lead acid batteries are the most commonly used as a lead acid battery is the most suitable for standby operation, as required by uninterruptible power supplies. Lithium-ion batteries provide greater energy storage density, faster cycling and are less susceptible to heat and can therefore be used in warmer operating environments. For some server rooms and data centres, the use of lithium-ion UPS batteries allows savings to be made in air conditioning and cooling systems.
