COWS Batteries

Q. I had a question about charging computer on wheel (COWS) at a hospital. The battery is a sealed lead-acid type. What type of restrictions are there on this style versus a lithium battery? J.L.

A. The basis for developing sealed lead acid batteries is to keep the acid from reaching it's gas generating stage during charging. Linked below is the Battery University page that describes these types of batteries. In addition basic HVAC design would be to provide a ventilation system that produces at least 1CFM per square foot of exhaust - thus any system should meet the requirements for exhaust. Don Rust
