Lithium-ion Battery Technology

Lithium-ion technology is revolutionizing UPS batteries. Compared to traditional valve-regulated lead-acid (VRLA) batteries, Prostar Lithium-Ion batteries offer significantly higher power density, up to three times longer lifespan, faster recharge times, and can withstand up to ten times more discharge cycles. They come with a standard 5-year warranty, providing more than double the useful life and significantly extended runtime.

Lithium-ion Battery VS VRLA

Feature	VRLA Battery	LiFePO4 Battery	Lithium-ion Battery Benefit
Standby battery life	3-5 years	More than 10 years	Up to 3 times longer life.
Typical cycle life	260-300	Over 3000	Up to 10x more discharge/recharge cycles available.
Battery recharge time	3-8 hours	< 2 hours	Fast recovery time, multiple outages can be handled over a short period.
Battery weight	Heavy	Light	Almost 40% weight reduction, suitable for smaller space and wall mount racks.
Warranty	1-2 year	5-year	Install and go - ideal for remote or unmanned locations.
