The UPS can operate in 104 degrees. The batteries will die at that temp.

The batteries are also a large issue as they require a constant temperature of around 20 to 24deg C if you expect to obtain the maximum life, as the biggest enemy of a battery is heat and the second enemy is to cold.
The other major problem is a mixture of dust and moisture which cause the system to over heat, the high power section to short and the electronic firing unites that creates the wave form to over heat.

In other works don’t stick it in a hot area dusty area that get effected by temperature change and moisture. This is the second most causes of UPS failure next to insufficient maintenance.
