Warning

If a battery has leakage or is damaged, it must be replaced, stored in a container resistant to
sulfuric acid and disposed of in accordance with local regulations.

The waste lead-acid battery is a kind of hazardous waste and is one of the major contaminants
controlled by government.
Therefore, its storage, transportation, use and disposal must comply with the national or local
regulations and laws about the disposal of hazardous waste and waste batteries or other
standards.
According to the national laws, the waste lead-acid battery should be recycled and reused, and
it is prohibited to dispose of the batteries in other ways except recycling. Throwing away the
waste lead-acid batteries at will or other improper disposal methods will cause severe
environment pollution, and the person who does this will bear the corresponding legal
responsibilities.

5.3.1 Installation of internal battery

For 15kVA to 20kVA standard UPS, internal battery and the cables within the battery string are
not provided as standard; if required, please contact your local agency.
For 15-20kVA UPS, 40 pieces of 7AH/9AH batteries can be installed.,
There are 40 batteries of to be installed, which are divided into 4 layers.Fig.5-1 shows the
installation of battery of the 15-20kVA standard UPS.
