Batteries in Radio Shelter Room - Offshore Application: 1

[NickParker]

Can Lead-acid wet batteries be placed in Radio shelter room. This room has equipment's of telecom like Tetra, GSM etc.?. These batteries are for Telecom equipment with 48V DC

This application is going to be Saudi Arabia. The temperature inside the radio shelter would be around 23 degree Celsius.

What are the Pros and cons on this? Should we go for VRLA batteries?

We have a dedicated battery room for other applications which is around 200 meters apart, but there is huge voltage drop involved and also we do not enough space in the battery room to accommodate this?

Lead acid wet batteries generate acidic vapours, which may corrode metallic parts of electronic equipment. VRLA batteries are better for this application.

Usually, Lead-acid batteries when used inside a common room are housed inside cabinets separate from the DC load/equipment!

NFPA 1; Section 52.3.3.1 Battery systems shall be permitted in the same room as the equipment that they support.

Please refer to NFPA 1.
