The UPS is equipped with long-life, sealed, valve-regulated lead-acid batteries (VRLA), also known as
"maintenance-free" batteries. The battery life depends upon the operating ambient temperature of the
UPS system. To prolong battery life:
• Keep the ambient temperature between 68°F and 77°F (20°C and 25°C)
• Prevent long low current discharges
• Charge the battery for at least 8 hours if the battery hasn't been charged for three months
when it has been stored at the specified ambient temperature, or two months when it has been
stored at high ambient temperature
The waste lead-acid battery is dangerous waste material. Its storage, transportation, usage, and disposal
must follow national and local laws and other criteria about dangerous waste material and waste battery
pollution prevention.
Per the related regulations, recycle the waste lead-acid battery. Other disposal methods are prohibited.
Disposing of the waste lead-acid battery in a landfill or other waste dump can result in serious
environment pollution and violates national and local laws.
Vertiv has a service network and recycle system to assist in complying with laws governing waste battery
disposal. Visit http://www.VertivCo.com/en-us/support/ for information about recycling the waste battery.
