Ventilating a Gel cell Battery Room
Ventilating a Gel cell Battery Room
(OP)
Need recommendations for ventilating an open area Gel cell type battery area. Surrounding conditions: air temp is @78 degrees F. NFPA 70E states to provide ventilation to maintain (battery) design temperature to prevent thermal runaway.

Use 10 ACH for exhaust air.
Cheers!

See 2006 International Fire Code, section 608.6.1.
Temperature control is also required for thermal runaway when dealing with valve regulated lead acid batteries (e.g., gel cells). However, some of the manufacturers have developed safety devices that de-energize the battery or battery string if it appraches a temperature to initiate thermal runaway. These devices are permitted to be used by IFC section 608.3.

Definitely don't use 10 ACH!
