Why should the battery cabinet limit the voltage difference
Nominal voltage defines the battery"s general operating range, charged voltage determines its full power capacity, and cut-off voltage ensures safe discharge limits.

Battery Room Ventilation Code Requirements
In order to reach a full charge, voltage above the battery''s capacity must move through the cells. Above about an 80 percent charge, then, forklift batteries tend to create a lot of hydrogen and oxygen, which

Battery Room Ventilation and Safety
To prevent the failure and the battery dry out, the safety valves open and the battery vents hydrogen until temperature and/or voltage are reduced. This condition can be triggered by charger over-voltage.

Why should the battery cabinet limit the voltage difference
Why do batteries need to be ventilated? The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
